The invention discloses a large-capacity and high-parameter environment-friendly gas-fired boiler that can adapt to various fuels. Economizers, flue gas baffles, lower economizers, high-efficiency air preheaters, and superheating and reheating systems; the lower part of the furnace chamber of the hedging type low NOx combustion power field boiler, the hedging type low NOx combustion The power field adapts to the stable and efficient combustion of various gas fuels, and can suppress the generation of nitrogen oxides in the furnace; It is arranged on the upper part of the furnace; the upper economizer, flue gas baffle, lower economizer and high-efficiency air preheater are sequentially arranged at the outlet of the boiler. The invention can adapt to the stable and high-efficiency combustion of various gas fuels, and can suppress the generation of nitrogen oxides in the furnace, with sufficient output, high thermal efficiency, low operating cost and good environmental protection performance. |
