Improved generation gas boiler structure

The utility model discloses an improved generation gas boiler structure, the aforesaid that aims at overcoming the blast furnace gas boiler existence among the prior art is not enough, provides one kind and can effectively reduce high -temperature economizer boiling degree, reduces boiler exhaust gas temperature, and need not increase an improved generation gas boiler structure of furnace size. It includes furnace, horizontal gas pass and vertical flue, and the furnace bottom is provided with the combustor, horizontal gas pass one end and furnace top intercommunication, and the vertical flue of horizontal gas pass other end intercommunication, horizontal gas pass has set gradually high temperature over heater, low temperature superheater and evaporimeter from the one end of connecting furnace, and vertical flue is in the horizontal gas pass below by last horizontal gas pass 0, horizontal gas pass 1 pre -heater, low -level (stack -gas) economizer and the low temperature horizontal gas pass 2 of having set gradually under certainly. The utility model has following beneficial effects: : (1 )Effectively reduce high -temperature economizer boiling degree and guarantee the economizer safe operation, (2 )Effectively reduce boiler exhaust gas temperature and combustion efficiency.
