boiler classification and application

Boilers all have their own service life, however, some old-fashioned boiler classification and applications have adapted beyond their useful life, and people continue to use them as long as they can still be used, thus increasing the hidden dangers of boiler safety. There may be unexpected consequences, so the gas-fired boiler has a longer service life than the old one. First, all things have their own life, if the boiler service life is longer, the pressure components appear serious corrosion, fouling, overheating and so on will improve the safety hidden danger. The gas-fired boiler solves the above problems very well, and the combustion of natural gas in the furnace will not cause dirt and temperature. Can be adjusted through the display screen will not cause excessive temperature, so greatly improve the service life of the boiler. Second, the design takes into account the height and diameter of the flame during natural gas combustion, which is a good collection of space in the furnace with natural gas, so that the flame does not scour the furnace surface and reduce the damage to the furnace surface. Improved efficiency while also protecting the furnace wall, such a design is very good. The design of gas-fired boiler can improve the service life of boiler itself, it is economical and economical, it can also supply well, and realize the function of boiler well.

Wall squib root cause lies in the deterioration of the water cycle, water wall due to lack of proper cooling. Wall water cycle resulting in deterioration factors are many, in the boiler classification and application normal operation, the main problems have stalled, back and soft drinks stratification.

For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.

1, to carry out special treatment industrial furnaces

Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.

2, to carry out clean alternative

Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.

3, to carry out comprehensive improvement of industrial boilers

Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.

4, strengthen upgrading gas-fired boiler

Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.

5, strengthen upgrading oil-fired boiler

Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.

6, vigorously promote urban central heating

Full use of existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of ​​central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .

Where pressure hot water boiler classification and application pressure hot water boiler with a different point in?

1, boiler pressure hot water boiler heating system is pressure equipment, with a risk of explosion. Pressure hot water boiler heating system boiler pressure is not always open to atmosphere. The boiler will not explode in any case, good safety performance.

2, pressure hot water boiler to be fitted with pressure gauges, water level gauge and thermometer only pressure hot water boiler, boiler due to the atmosphere, the pressure pot is always atmospheric pressure, there is no risk of explosion, without having to install a pressure gauge.

3, circulating pump pressure hot water boiler heating system is pumping systems engineering backwater sent to the boiler, water pump is generally used. Minutes circulation system to overcome the resistance, but also to maintain the boiler there is a certain pressure to ensure that water does not pan evaporation at high temperatures. Circulating pump pressure hot water boiler heating system is pumping water from the pot, heat pumps are pumps, its role is to overcome the resistance of the system, mainly to overcome the resistance of the valve regulating backwater.

4, pressure hot water boiler can not only supply low-temperature water, but also to supply high-temperature water. Pressure hot water boiler can supply low temperature water <100 ℃ of.
