Gas And Oil Fired Steam Boiler

It is understood that in order to successfully promote the transformation and development of traditional coal chemical industry, January 1, 2019, letter to the Office of Henan Province workers released a special action program (hereinafter referred to as the "Program"), to promote pollution prevention campaign of Henan Province, three-year action implementation of the scheme, to speed up the traditional coal chemical industry (ammonia, methanol) industry green transformation, to achieve high-quality development. "Program" details are as follows.

First, the key tasks

1, and strictly control new capacity. Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity.

2, increase the relocation and reconstruction efforts. Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of ​​coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), in situ transformation of the company to implement the upgrading of the standard industry benchmark, off-site relocation of enterprises to According to large-scale, modern principles move into the province for involving chemical industry gathering area.

3, Green transformation. Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. In accordance with national requirements, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place.

Second, the organization and implementation

1, roles and responsibilities. Relevant provincial jurisdiction over municipal government on the development of local coal chemical industry restructuring and overall responsibility, strengthen organizational leadership, with local conditions, the development of coal chemical industry restructuring and development program implementation, implementation tasks initiatives. Coal chemical industry is the main responsibility for the implementation of the restructuring and development, to strictly implement the main responsibility for production safety and environmental protection, the implementation of the relocation of the green transformation. Provincial Industry and Information Technology Department, Development and Reform Commission, the ecological environment, the Office of Emergency Management and other provincial departments according to the division of responsibilities, strengthen guidance and improve relevant policies and measures.

2, strictly implement the policy. Comprehensive use of market mechanisms, economic instruments, legal and necessary administrative means to approach, to promote enterprise restructuring and development. Strict implementation of China's industrial policy, strictly enforce the standards of environmental protection, quality, energy consumption, safety and technology. Relocation and reconstruction of urban population centers dangerous chemicals production enterprises and urban built-up area of ​​relocation and reconstruction project focused on heavy polluting industrial enterprises, shall be given support in terms of fiscal policy, tax incentives, financial support, land policies.

3, strengthen supervision and accountability. Strengthen supervision of new capacity alone, without approval of the establishment of Chemical Industry Park, unauthorized implementation does not meet the industrial layout planning requirements of coal chemical projects, in violation of the registration and management of hazardous chemicals and construction projects "three simultaneous" (also designed, constructed, and concurrent use of illegal activities) system, etc., must be severely accountable accountability.

About the advantages of gas-steam oven gas is mainly reflected in what way in recent years, with the continuous development of the boiler industry, a variety of devices including gas, including gas-steam oven has been further developed and applied. We know that the production of each device can be widely used. It has its own advantages, the main advantage of what gas furnace gas and steam are we talking about today? According to reports, the gas can understand that gas-steam oven does not require the accumulation of ash, thus eliminating area. When the gas for a fuel delivery gas steam oven, other auxiliary machines less, low-power, continuous operation time is short, and therefore at a high level, saving electricity. Production of heat transfer oil boiler. Others because the gas furnace gas and steam will now run out of dust and pollution, natural gas is used as a clean energy source. In the Gas Gas steam oven operation, no pollution, and it is easy to achieve. Nightly environmental needs. Daily use of gas gas steam oven needs maintenance. When not in use the boiler, should carry out maintenance and maintenance. This will not only extend life, but also can reduce the use of various problems arising in the process. First of all, when not in use boiler, heat transfer oil to be discharged of all internal, because if there is oil, the quality will change. If a leak occurs, it will affect the surrounding environment, and needs to be cleaned after release. Clean the inside of the boiler to maintain and keep other impurities. Secondly, regularly check the various components of the gas oil furnace to see if there are loose. After maintenance, the boiler can be stored, can be used directly in the next use, not other problems. Xiao Bian remind you, after using a gas furnace gas and steam for some time, the loss will occur. If the loss is too large, it will affect their use, particularly in certain connections and transmission loss larger. Add lubricant to reduce the loss of these components and more stable performance of the boiler.

Steam and hot water boiler water level gauge fault safe hydraulic machine operating company of Henan fast boiler with small series to introduce a common and oil fired steam boiler water gauge Problem safe operation of steam and hot water boiler water gauge failure of hydraulic machine, the causes and solutions approach a hot water boiler steam water gauge reason and common problems: 1, the water level is too low mounting table; 2, water table, even the water pipe is too small; table 3 have low level or a water level indicator, when active, only one only water table; 4, the ground water table, drain cocks no drainage; 5, a drum water level on the table is valid, another water table damage; 6, the tap water gauge screw fixed; 7, the tap water gauge leak, leaking; 8, the performance of the water table level false; 9, the drum water level in the water table irregularities two inconsistent; water gauge glass often broken; 11, water level gauge glass without guard; 12, water gauge low water level glass plate not shown in the red line instructions; 13, glass plate dirty water table, the water level observation is unclear. The main reason is because of 1-4 above design, installation or alteration of dislocation caused. When the steam boiler with a low water table position when the drum is only a case of the water table, water table because the internal balancer lowland leakage short-circuit (at that time can not be detected), resulting in the emergence of lowland water table high water level ( the so-called full of water), and the water table on the drum performance but low water level (or even probably not see the water level), then the fireman because they can not determine the true level of the boiler will go immediately and check the water level in the drum on the table, it will be very serious water shortage in container delays when the boiler accident occurred. Glass-sided water table in front of a glass sheet metal frame box lined with asbestos pad contact surface made of cardboard and then screw the cover frame and the cover pressure closely. Some even show the water level too low trust status of the water table, and take a little sewage, mistakenly steam boiler water when filled with water incident handling, accelerate the production of the accident, there is precedent for such incidents to be investigated. Then, the above-mentioned reasons hinder 5-9 problem occurs mainly boilers lasting not run when washed in water table, not routine maintenance, resulting in water gauge cocks rust, gas, water and even the block, or insufficient packing or aging deterioration. False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water table caused by misalignment connection; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the boiler priming and thrown false water level. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water table is at the window glass is a cold draft, and the glass pipe quality was poor. Safe operation of hydraulic machine 1, hydraulic machine operator must be trained to master the equipment performance and operating techniques to work independently. 2, before the operation, you should clean up various debris on the mold, wipe any dirt hydraulic rod. 3, the mold must be installed hydraulic machine in case of power failure, and prohibit the collision start button, the lever foot on the footswitch. 4, installed on the upper and lower dies, the die gap adjust, unilateral allowed off-center, a good confirmation of the fixed mold pressure again. 5, before the hydraulic machine is first started working apparatus idling 5 minutes while checking whether enough oil tank, pump noise is normal, the hydraulic unit and pipes, fittings, if the piston leakage phenomenon.
