A few little knowledge about low nitrogen boilers


Release time:

2022-08-01

According to the environmental protection technical requirements of the enterprise, the national development of the industrial economy vigorously carried out the project of implementing the transformation of the energy system for cleaner production of boilers, and the small coal-fired boilers were changed to new energy devices such as "fuel, gas or electric boilers". Especially in China in recent years, the Beijing-Tianjin-Hebei and northwest ethnic areas have serious smog, so our country has not only raised the environmental protection emission management requirements of construction industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented the most stringent NOx emission-related standards in history, which has accelerated the process of marketing and promotion of low-energy and low-nitrogen boilers.

A few little knowledge about low nitrogen boilers:

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

According to the environmental protection technical requirements of the enterprise, the national development of the industrial economy vigorously carried out the project of implementing the transformation of the energy system for cleaner production of boilers, and the small coal-fired boilers were changed to new energy devices such as "fuel, gas or electric boilers". Especially in China in recent years, the Beijing-Tianjin-Hebei and northwest ethnic areas have serious smog, so our country has not only raised the environmental protection emission management requirements of construction industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented the most stringent NOx emission-related standards in history, which has accelerated the process of marketing and promotion of low-energy and low-nitrogen boilers.

2. Fully premixed combustion technology for low nitrogen boilers (combustion)

The combustion technology of low-nitrogen boilers should be more advanced, the pollution-free index should be lower, the fuel ratio should be more appropriate, the combustion should be more sufficient, and the overall energy consumption can be greatly reduced. Moreover, the flame spreads faster, the combustion intensity is higher, and it can supply heat in an orderly and continuous manner. According to relevant persons, this low-nitrogen boiler does not need to worry about other problems of insufficient chemical combustion.

3. Energy conversion of low nitrogen boiler (highest thermal efficiency)

Boiler is a kind of energy conversion equipment, professionally used to produce and use high-grade heat energy of low nitrogen boiler, gas boiler, mechanical (solid) incomplete combustion heat loss and ash physical heat loss can be ignored. The only way to improve boiler efficiency is to reduce heat loss and exhaust flue gas temperature.

For public works projects, general enterprises use two different forms of municipal thermal central heating and users' heating through self-built boiler rooms. With the low-nitrogen boiler heating system, the development of the low-nitrogen boiler control system has a very high load regulation and learning ability, which can be well matched to the user's load change, and the operation energy saving effect is significant, saving the operation cost for the user. Nitrogen boilers are widely studied and used in public projects.
