hot water boiler over 35 mw price

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.

Why can't the water entering the boiler be "hard water"?

"Hard water" means water containing more, soluble, calcium-magnesium compounds. Regardless of whether you purchase a hot water boiler or a steam boiler, the boiler technicians will repeatedly emphasize that the water entering the boiler must be water treated soft water. Why is the boiler's water requirements so high?

Low thermal load combustion of natural gas, gas-fired boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. The fuel gas-fired steam boiler can be divided into natural gas, city gas steam boiler, a steam boiler coke oven gas, LPG and steam boiler; according to the structure can be divided into vertical and horizontal steam boiler steam boiler. Gas boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving , more economical, and a waveform furnace threaded pipe structure, i.e. increase the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.

Core condensing boiler technology: condensing boiler technology core of low nitrogen premix combustion technology: metal fiber premix burner is a low nitrogen gas and the air proportion is completely mixed prior to entering the combustion chamber, combustion of natural gas, while reducing the air demand, increase the dew point of the flue gas, the flue gas is condensed into the early stage, in order to further improve the combustion efficiency; while reducing the flame temperature to reduce generation of NOx, the NOx emission at the lowest operating conditions can be controlled to below 40ppm.
