which type of boiler is supercritical boiler considered

Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's which type of boiler is supercritical boiler considered was planned.

Xuchang coal-fired boiler governance objectives:

In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.

Coal-fired boiler subsidy:

(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.

Xuchang boiler out of the way:

Removal, central heating alternative, coal gas, coal to electricity, use geothermal, wind, solar, biomass with a bag filter, to burn not including clean coal, coal-water slurry, anthracite, charcoal blue, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

This method is at the time of shutdown, when the temperature of the which type of boiler is supercritical boiler considered water is reduced to 100 ~ 120 ℃, for drainage. When the water exhausted by the furnace heat, hot air furnace or introduced Microflame point, the inner surfaces of the boiler and drying.

Why low nitrogen which type of boiler is supercritical boiler considered? Referred to this issue, I believe we all understand the importance of low nitrogen boiler, in response to the strong support of the national environmental policy call, more and more manufacturers are choosing low-nitrogen boiler to replace the previous old equipment, and for those emission targets exceeded factories and enterprises, the state is stepped up efforts to punish and suspend business for rectification uncommon, has become the norm, therefore, despite the high cost of low nitrogen boiler, but for long-term development of enterprises and ecological environment smooth, we had to join the ranks go. What are the advantages compared to ordinary low nitrogen gas boiler boiler advantage of low nitrogen gas boiler products mainly in the following aspects:? 1 condensing technology to reduce harmful emissions of harmful substances carbon dioxide and nitrogen oxides and condensation in condensing flue heat recovery tail water generated corresponding acid binding, and with the condensed water is discharged, so that harmful components carbon dioxide and nitrogen oxides in flue gas is further reduced, a region up to the national standards, in line with development of national environmental policies. 2. Installation convenient, easy routine maintenance of post-installation site and system maintenance no special requirements, external flue gas recirculation structure only increased circulation flue pipe to the burner, by simply connecting to; adjusting the air volume control section, filtered the process provided in the burner means; field installation to ensure reliable insulation and fixing, provided a bottom drain water outlet conduit; routine maintenance no difference with the standard product. 3. The Structure of Scientific boiler heat is efficient boiler special structure to ensure adequate gas back recycling space. The furnace volume heat load control within reasonable limits, for a variety of types of combustion. Smoke tube arrangement optimization to solve problems flue gas recirculation flow rate of the flue gas caused the increased flue gas volume, gas resistance and no significant increase in the standard comparison product. Larger water volume design, fluctuations in boiler load insensitive. Boiler water level stable, further reducing the probability of combustion instability. 4. Remote Monitoring Intelligent Expert System to provide protection for the safe operation of the boiler.

Note that although the problem with the which type of boiler is supercritical boiler considered with a new iteration generations of the product, its operation also become more and more intelligent operation Henan condensing gas boiler. However, some details of the system is still not resolved, and "boiler man" who, in practice the process of Henan condensing gas boiler must pay attention to these issues in order to avoid damage to the machine, even "boiler room disaster." 1, to ensure ventilation Henan condensing gas boiler 2 has sufficient oxygen gas pipeline leak valve 3, Henan condensing gas boiler furnace to open, after the shutdown, the need to ensure that the main steam valve 4 is closed, the first air supply pipe and the need to ensure points water emptying the cylinder, the valve slowly aspirated, to warm up the pipe to prevent water hammer 5, the initial points on the furnace must be maintained at 20% of the manual state to an automatic state switch 6 is prohibited, Henan condensing gas boiler feed duct the outlet, is strictly prohibited blocked and keep clean the outlet 7, the boiler need to ensure a pressure not less than 0.7mpa8, manually adjust the boiler firing rate, must be adjusted stepwise (at intervals of 10%) 9 boiler when the boiler when the failure occurs, pressure is lower than 0.4MPa, the steam temperature is lower than 150 °, the main steam valve must close again according to the operation procedure from the furnace.
