Basics gas and steam oven basic principle as the principle gas steam boiler and knowledge: steam as a heat carrier gas, forced circulation pump circulating the liquid phase, and then reheated to return, once-special industrial furnace. Widely used, such as petrochemicals, textiles, printing, plastics, rubber, food processing, wood processing, thermal asphalt, carton production, vegetable dehydration, drying, and other drying foundry sand. Gas steam boiler is an energy, security, heating equipment, is an ideal alternative to steam boiler products. The working principle is conveyed back to the respective thermal heating apparatus petroleum oil heater (endothermic) (organic heat), heat conduction through the (thermal energy release), and then returned to the furnace, formation of a closed circle in the process of compulsory to achieve the purpose of heating. Performance and features: 1, low temperature. As the temperature rises conductive oil, the viscosity of the system will continue to reduce resistance to decline, it will also reduce stress, more conducive to the safe operation and safe operation. Steam boiler is high pressure high temperature plume. 2, gas and steam heating system uses hot water inlet and outlet temperatures and equipment is 20-30 degrees, the closed forced circulation, heat recovery can be repeated, there is no waste, high thermal efficiency, energy-saving effect. 3, a low pressure gas and steam heating system, requires pressure equipment and the system will be reduced, and therefore, a simple production process of steam boilers, low investment costs. 4, the thermal efficiency can be maintained at optimal levels in various loads a level of 320 degrees and can adapt to the production requirements of the following types of thermal load, and temperature control can be precisely adjusted. 5, heating furnace to increase two to three times the temperature cycle can provide a wide range of processes, a variety of equipment to meet the different temperatures greatly reduces the need for investment in equipment.
Gas-fired steam boilers are a very wide range of special equipments, widely used in food, chemical, paper, textile, construction and other industries. In the process of loading and installing a gas steam boiler, some problems must be paid attention, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
5. The fire resistance grade and fire protection requirements of the boiler house building shall comply with the requirements of the Code for Fire Protection of Building Design and the Code for Fire Protection Design of High-rise Civil Buildings. The ground of the gas steam boiler room should be flat, non-flammable, no water accumulation, and the foundation load should meet the requirements. The power supply voltage of the gas steam boiler room should be stable to avoid causing the electrical components to burn out. If the voltage is unstable, it is recommended to install a voltage regulator. Ventilation equipment should be installed in the boiler room, and the boiler should be kept at room temperature below 50 °.
In recent years, Siyang County town chrysanthemum industry as part of the ecological projects to enrich the people in the choice of chrysanthemum drying equipment, the county Environmental Protection Agency proposed to replace coal-fired boilers to electric boilers idea. Part chrysanthemum growers is objected that the idea costly and cumbersome, but after analysis and explanation of the Environmental Protection Agency and the power company personnel, electrical boilers have a deeper understanding of the use of electric boiler can not only improve drying chrysanthemum chrysanthemum quality and product phase, it did clean, safe, and there are various government subsidies, while coal boiler if the government out of the use, post-investment costs will be higher. At present, the boiler "electricity for coal" action has been noticed.
In recent years, Siyang County uphold the "gold and silver mines that lies to" development concept, vigorously implement alternative energy projects, alternative energy gradually extended to grain drying, drying fruits and vegetables, herbal drying and bathroom, hotels, restaurants, businesses and other industries. Siyang county party secretary said: "Winning 'Battle of Blue Sky', shouting slogans alone are not shouting to the sky, or from the 'coal to electricity,' 'oil to electricity' these specific things to start, through the implementation of alternative energy engineering, elimination of high energy consumption, low-energy-efficient equipment, the progressive realization of ecological priority, green development goals. "
Since 2016, the county completed a total alternative energy companies, service unit 686, phase out coal boiler 1336 units, to complete alternative energy electricity 256.69 million kwh. Energy saving alternative to business spending, reduce production costs and improve their efficiency and realize a production of "zero emissions" to protect the party clear water and blue sky. In mid-November, Siyang County was selected as "the second batch of national ecological demonstration counties civilization."
Small steam boiler works with its basic principle is the use of small steam boiler: by an automatic control device, to ensure control liquid during operation or high, medium and low probe feedback control electrode opening of the pump, is closed, water supply length, furnace heating time; it is set by the pressure relay with the maximum vapor pressure steam output, the water level falling furnace, when in the low water level (mechanical), water level (electronic), automatic replenishment pump, to the high level, the pump stops replenishment; At the same time, the electric tube furnace heating was continued, a steady stream to produce steam, the upper portion of the top panel or instantly display the steam pressure gauge pointer value, the whole process can be automatic by means of LEDs display.
