Wall -mounted boiler manufacturers: Why should we vigorously promote low -nitrogen condensed boilers?  

The problem of energy and environment is two issues that humans are very concerned about the 21st century, and one of the important strategic issues that my country and the world must adhere to sustainable development. Due to the development of the economy, boilers have become an indispensable thermal power device for people's lives, but boiler emissions have also aggravated air pollution. As a result, the advantages of low -nitrogen condensation boilers produced by wall -mounted boilers are reflected.

1. Reasons for promotion of low nitrogen condensation boilers (strong environmental protection)

According to environmental protection requirements, small coal -fired boilers have been vigorously implemented by industrial industries to vigorously implement boiler clean energy transformation projects. Small coal -fired boilers have been changed to new energy devices such as "fuel, gas or electric boiler". Especially in recent years, the haze in Beijing, Tianjin, Hebei and the northwest region have been serious, so the country has improved the environmental protection requirements of industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented more rigorous NOX emission standards in history, which accelerates the process of market promotion of low -nitrogen condensed boilers with lower energy consumption.

2. Full premixing combustion technology of low -nitrogen condensed boilers (more combustion is more sufficient)

Low nitrogen condensate boiler combustion technology should be more advanced, its pollutant -free index is relatively low, and the proportion of fuel is more appropriate, the combustion is more sufficient, it can greatly reduce the overall energy consumption, and its flame transmission speed is relatively fast and relatively fast. The combustion strength is relatively high, and it can have a methodical continuous supply of heat. The technical staff of wall -hung boiler manufacturers introduced that this kind of low -nitrogen condensed boiler has almost no need to worry about other chemical burning problems.

3. The energy conversion of low nitrogen condensation boilers (its heat efficiency is higher)

Boiler is an energy conversion equipment. Professional low -nitrogen condensation boilers are high -quality heat energy for production and life. For gas boilers, incomplete burning heating loss and ash physical heat loss can be ignored. If you want to improve the efficiency of boilers, you can only reduce the loss of heat dissipation and reduce the temperature of the smoke.

For public projects, wall -hung boiler manufacturers generally recommend the use of municipal heating central heating and user self -built boiler room heating. The use of a low -nitrogen condensed boiler heating system, the low -nitrogen condensation boiler system has very high load adjustment capabilities, which can well match the user's load changes. The operating energy saving effect is significant. Save the cost of operating for users. The low -nitrogen condensed boiler should be in public projects in public projects. Widely used.
