big discount refractory for steam boiler

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.

In order to maintain the evaporation of the boiler, the same air-fuel ratio to warm Changsha basis having increased fuel and air, flue gas flow increases, due to constant flow area of ​​the flue, where the flue gas velocity superheater is also increased, in accordance with the steady state force guidelines have convection equation, the effect of increasing the flow rate of the flue gas side is the convective heat transfer coefficient of n-th power of the gas velocity, n = 0.6-0.65.

First, hot water boiler energy consumption caused the main reason is that the lack of unified planning boiler before being put into use in the development plan, no comprehensive analysis and identify issues, for hot water heating, and with the new piece of planning lack of understanding of the problem. Therefore, when building the boiler room, there may be a planning area does not match the actual area occupied or poor interfaces connecting pipes, etc., the boiler barely put into use, energy efficiency, achieving the desired effects.

As the seasons change or other circumstances affecting the user demand for heat output of the boiler also varies. Fast square low nitrogen gas boiler can be combined control of multiple operating mode, the number of operating flexibly adjusted according to different needs of users, can satisfy the needs of the user, and avoid unnecessary waste.
