200w u type industrial water boiler tubular heaters

Is there a greater change in the thermal efficiency of the boiler under different loads? Each boiler has an economic load range, generally about 75% to 100% of rated load of the boiler, than this load, the efficiency is decreased below this load, the efficiency also decreased; for each boiler furnace and smoke channel capacity is fixed, when the rated load is exceeded, causes the fuel in the furnace residence time is too short, not enough time to be taken out of the combustion furnace, resulting in increased heat loss chemically incomplete; because excessive smoke, smoke flow and flue gas temperature of greater than normal, causing a large loss of the flue gas, reducing its efficiency. In the low-load operation, since the furnace temperature drops more, burning disturbance weakened, incomplete combustion heat loss increases, boiler efficiency will be reduced.

To further promote air pollution control tough fight, push the air quality continues to improve, according to "Zhengzhou City, the 2018 campaign of air pollution control plan" and "Chung Dong New Area, the 2018 campaign of air pollution control plan" requirements, the area to carry natural gas boiler low nitrogen renovation work, hereby notify the relevant issues as follows:

(1) before the end of September 2018, Eastern 4 tons of steam boiler and above the implementation of low-nitrogen gas engineering construction and renovation. Encourage the implementation of other gas-fired low-nitrogen transformation.

Promote the transformation of low nitrogen gas boiler according to early completion, and more reward principles, decreasing year by year funding award up mode. Before the end of June 2018 to complete the construction of low-nitrogen transformation, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 40% of equipment investment; before the end of September 2018, to complete the low nitrogen renovation project construction, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 30% of equipment investment; before the end of April 2019 to complete the project construction and renovation of low-nitrogen, nitrogen oxides Or emission concentration higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 15% of equipment investment;

After construction is completed, the project in a timely manner to submit an application to the territorial review township (town) office: the township (town) office on a preliminary review of the whole process of the project, the project area through on-site verification of materials (including: project implementation plan, completion report, monitoring reports, on-site verification opinions, etc.) reported the construction of the Environmental Protection agency, the EPA reported by the construction of the Municipal Environmental Protection Bureau atmosphere, the atmosphere at the Municipal Environmental Protection Bureau organizations to monitor third-party monitoring mechanism for acceptance, qualified after monitoring the municipal government finance awards complement funds, unqualified deadline for rectification.

Application of Gas boiler market expansion, in addition to its own environmental advantages have encountered, but also thanks to the large environmental impact. In the country and more have been carried out phase-out and transformation of governance coal-fired boiler, high pollution and low efficiency of coal-fired boilers shall not new and expansion, high gas boiler cleaning environmental protection efforts been vigorously promoted and used.
