Municipal Agricultural Bureau, the Municipal Office of the sugar industry to strengthen guidance and support for the comprehensive development of the use of sugar cane leaves, the full implementation of mechanized harvesting of sugarcane, sugar cane fields and comprehensive utilization of straw has broken.

2, urban dust comprehensive management of special operations. The urban dust control content into the focus of supervision and improve the system of dust control mechanisms, the establishment of the construction site with information technology platform construction, water conservancy projects, the implementation of dynamic site inventory management. Supervise the implementation of the site around the site enclosure, stockpiling cover, wet earth excavation work, the main road hardening, cleaning out the vehicle, sediment transport vehicles sealed "six percent", temporarily unable to start construction land should be covered. The construction site dust pollution prevention and control into the "civilized construction" category management, dust control costs are included in the project cost; according to the law will not be in place of harmful dust management information into the construction market credit management system, in serious cases, be included in the construction market players " blacklist". Rinse vigorously promote road sweeping mechanized operations, improve road mechanized cleaning of urban built-up area. Sediment transport, coal, ore, gravel and other transportation vehicle is not confined to do, strictly punished according to law.

3, industrial enterprises air pollution comprehensive management of special operations. According to Beihai City "scattered pollution" inventory accounting, to further improve that standard and rectification requirements, classification of promoting the "messy dirty" business regulation, focusing on remediation of the city and the surrounding "messy dirty" business. Strengthen the coal-fired boilers (including biomass boilers) and brick, ceramics and other industries industrial furnaces supervision, strengthen law enforcement. Encryption of iron and steel, building materials, nonferrous metals, thermal power, cement, brick, calcium carbonate and other business materials (waste) storage, handling, crushing, transportation and other aspects of the inspection frequency of inspections, strict implementation of consecutive daily penalties, limited production shutdown and other means strictly according to law penalties for environmental violations. Focus sessions focused their attention on the process of pollution, thermal power, steel, cement, bricks, ceramics, wood processing, sugar high emission enterprises, especially in built-up urban area of ​​business, and strictly control the total amount of air pollutant emissions.

Gas-fired steam pass steam packaged firetube boiler blowdown processing techniques which use any boiler blowdown must be, otherwise it will affect the normal operation, slowing the life of the boiler: the definition of sewage: In order to meet the standards of boiler water, impurities in the water must be controlled within a certain range, this requires removal of salt from the boiler, the boiler water higher alkali content and depositing in the bottom of the water, sludge-like precipitate and loose, this process is known as blowdown. Sewage Purpose: Excluding these sediment discharge, will affect the quality of steam, but also the inner wall of the boiler scale build-up, resulting in poor water circulation normal operation, the impact of the boiler. Thus, the formation of impurities to be discharged into the boiler, to ensure that the salt content in the range of the allowable water boiler, which is the object of the sewage. Sewage mode: continuous blowdown also called surface discharge. This sewage uninterrupted manner i.e. the maximum concentration of the boiler water from the boiler water a boiler discharge surface layer, which role is to make the salt content of the water and alkalinity reduction furnace, otherwise, excessive concentration of boiler water steam quality will be affected . Also referred to as sewage regularly or intermittently bottom blowdown discharge is intended to enable the accumulation of slag in the lower portion of the boiler and the precipitate is excluded. Although the duration of each periodic discharge is not long, but it has a strong ability to discharge pot precipitate. 1, the sewage water level in the boiler to be at low load is slightly high vapor pressure and good low load, the boiler water circulating slowly, resulting in easy accumulation of dirt in the drum, the bottom of the collection tank, and the high vapor pressure: Note sewage high blowdown flow, to facilitate the discharge of dirt. Thus, when the boiler blowdown water level should be maintained in order to operate the sewage at around 60%, it must be set when the sewage someone to operate closely monitor changes in the water level to prevent water shortages. 2, the drain valve should open each short intermittently discharge opening quick-closing speed, disturbances caused by dirt slag, thus repeated several times, the precipitate was suction rely possible to quickly meet at outfall, then concentrated discharge. To control the right time, not too long, usually once a sewage must be in the 30s of the time. If the discharge time is too long, the water content of soil furnace will be gradually reduced, so the effect of variation not only sewage, emissions have increased, not only a waste of energy, but also affect the boiler water circulation, and even burst pipe failure may occur. 3, the observation of a given row Expander sewage after the steam outlet, must touch the outfall temperature, and view given row Expander air outlet, in order to determine whether or not to confirm the drain valve is fully closed. Ruoyin debris stuck in the spool of the leak can be re-opened after a rapid close, if the issues shutting the valve wear and difficult, should strengthen surveillance, arrange repair or replacement as soon as possible, at the same time, should be prepared to shift on the record corresponding record, for subsequent inspection.

How hot water pass steam packaged firetube boiler equipment selection softening boiler water softening object is to remove calcium and magnesium ions, reduce water hardness and avoid prolonged substandard boiler feed water boiler causes scaling, corrosion, burst pipes and so on. Then the hot water boiler softening equipment selection should be how to do? (1) To have a clear understanding of the customer's actual water consumption, water consumption, including water volume and per unit time. In order to facilitate a reasonable selection for customers. (2) understand the customer's frequency of water, the water supply is continuous or intermittent water supply, we must be clear in order to identify the customer water consumption. (3) Customer boiler to the environment. To the customer the boiler water to water quality testing, acceptance be put into use. Hot water boiler softening equipment, boiler operation process is an indispensable auxiliary configuration, for Therefore, when the boiler running smoothly, reduce the cost of manual maintenance, security, performance boiler has a relatively high contribution to the efforts in the selection, must be carefully considered, we must not be careless.

For different working pressures pass steam packaged firetube boilers, to have a separate steam pipes and water pipes, respectively. If when a combination of the main steam pipe, the steam pipe to be fitted with high pressure apparatus and the automatic depressurization safety device that prevents the low-pressure side of the overpressure. When the water pressure does not exceed 20% of the maximum pressure, the system can feed water to the boiler feed water from the total.
