gas hot water vacuum water tube boiler

Recently, Dezhou City, Shandong Province, has released the main points of pollution prevention and control in 2019, set specific targets and implement measures to control emissions of persistent pollutants SO2, NO2, to reduce the number of aspects such as severe pollution days.

1, continued to promote the total coal consumption control. Strictly implement the coal consumption reduction, equivalent alternative policy requirements. Continue to implement the monitoring and early warning mechanism to control the total amount of coal, coal consumption for the counties (cities, districts) were scheduled monthly, quarterly analysis, forecasting and early warning and timely release. Refined coal decomposition control mission objectives to ensure the completion of the annual total coal consumption control tasks.

2, strengthen renewable energy development and utilization. Actively promote wind, solar, biomass, geothermal and other renewable energy sources, promotion of power generation, industrial and residential heating and other heating applications. Achieve renewable energy consumption accounted for the proportion of primary energy consumption of more than 15%.

3, continue to promote the management of coal-fired boilers. The existing 35 tons of steam coal-fired boilers, according to ranking policy before the end of 2019 included in the phase-out plan. The inclusion of out of range, to ensure that out of the task before the end of 2020.

4, the implementation of low NOx combustion gas boiler reconstruction. To 2020 basically completed the transformation of low-NOx combustion as the goal, listing the existing inventory ledger gas boiler, to determine the transformation of an object, complete renovation in 2019 total about 50%. After transformation of NOx emission in principle higher than 50mg / m3. Achieve a stable concentration of nitrogen oxide emissions rebuilt 30mg / m3 or less (that is, ultra-low NOx combustion requirements) can be appropriate priority in provincial subsidies make up ecological civilization prize funds.

5, continue to promote clean coal. Strengthen clean coal production, supply, construction and distribution system, and continue to improve the implementation of the subsidy policy, to ensure the timely distribution in place to protect the people warm winter. Bulk coal market to strengthen the comprehensive improvement of law enforcement, the implementation of three coal detection mechanism to prevent inflow of low-quality bulk coal, clean coal to ensure quality standards. 2019, on the basis of full coverage in clean coal, continue to promote clean coal.

6, strengthen high-pollution fuel combustion zone ban construction. Combustion zone ban, a ban on new or expanded high-polluting fuel burning facilities have been built to the deadline to switch to clean energy. Investigate and punish illegal construction, expansion and high-polluting fuel facilities are not completed within the prescribed period rectification behavior. Ban on burning coal for a total ban on the circulation area.

7, continue to promote clean heating transformation. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. Accelerate the pace of production, supply and storage of natural gas marketing system construction and gas storage facilities, improve air support capabilities. To develop multi-gas source, priority for clean heating, ensure safe and stable gas. Strengthen heating, gas facilities construction, expanding the central heating, gas, geothermal heating coverage. Accelerate the clean heating renovation project, before November 15, 2019 to complete the annual task of transformation goals. Complete power-generation coal, gas and other clean coal generation of heating transformation of the region, a total ban on bulk coal sales, to prohibit the sale and hoarding bulk coal, bulk coal to prevent the re-burning.

Many users in the purchase of the boiler, the boiler type for "vacuum boiler" always have doubts, do not know what the concept of the boiler, can you use in your enterprise. Fast boiler manufacturers come to tell you about, what the vacuum hot water boiler Yes.

Vacuum hot water boiler fuel gas vaporized to produce vaporized overtemperature problems reasons vacuum hot water boiler fuel gas, there are two major surfaces, one is vaporized over temperature, there is a is a partial vaporization, the causes leading to also have different, corresponding solutions are different. If the fuel gas vacuum hot water boiler heating system and hot water circulation loop gravity, it must be open gravity circulation valve. Because once the system failure caused by constant pressure boiler pressure device or system to reduce leakage, the position will not be caused by pressure vaporization system. After this case should an emergency shutdown immediately, and quickly identify the reasons, causing the system pressure to be reduced to exclude faults, the need to make the system running for some time in the cold state, until constant pressure returned to normal in order to determine the role of put into operation again. The local boiler vaporization problems are likely because of poor internal fuel gas vacuum hot water boiler water circulation conditions, the presence of water stagnation zone, tube angle is too small, the water velocity is too low and so on; there may be a forced circulation boiler (back the introduction of improper water distribution pipe layout, flow maldistribution caused when the fuel gas vacuum hot water boiler occur more serious pot of water vapor, combustion equipment should be stopped, but the circulating pump should continue to run at the same time open the occurrence of vaporization backwater valve circuit, to increase the flow of water. when the water hammer tube disappears before gradually returning operation of the combustion equipment.

Steam electric boiler maintenance and fast boiler pump classification Henan Xiao Bian told you about the company's steam boiler maintenance and electrical vacuum pump steam boiler maintenance classification should pay attention to 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve. The vacuum pump is divided according to use: a roughing pump starts to decrease from atmospheric pressure to a vacuum pump system to work the other pumping systems. 2. High vacuum pump operating in a high vacuum range. 3. The main pump in the vacuum system, the vacuum pump used to obtain the desired degree of vacuum. 4. foreline pump foreline pressure is maintained for a further vacuum pump in which a pressure below the critical backing. 5. coarse / low pressure pump starts from the atmosphere and for obtaining a low degree of vacuum of the vacuum pump. 6. The booster vacuum pump is mounted between the low and high vacuum systems to improve the efficiency or reduce the vacuum foreline pump capacity requirements. 7. The ultra-high vacuum pump works in the ultra high vacuum range. 8. A pump is maintained in a vacuum system, when the gas amount is small, can not be effectively utilized master, before the pump, In this case, with a smaller capacity auxiliary backing pump to maintain the main pump containers or maintain a desired degree of vacuum . Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
