Description
Technical field
The utility model relates to biomass boiler technical field, and particularly a kind of is the clean burning system of firing block waste wood by coal-fired boiler reform.
Background technology
Because existing boiler just uses for fire coal, the feature that there is high pollution and the defect wasted energy, when fuel is living beings, boiler also has a lot of deficiencies, has fuel selectivity and the undesirable shortcoming of combustion efficiency, and environmental pollution is serious, the problem that equipment corrosion is serious.Volatilizing in biomass fuel does not burn completely just taken out of boiler and biomass fuel igniting easily burn out coal flashboard rapidly, the flying dust produced after boiler combustion not easily removes.
The burner hearth that waste wood is directly sent into combustion coal chain boiler by some enterprises burns, and due to not of uniform size, different, the timber of bulk and plank burn insufficient due to anoxic, and chimney is emerged a large amount of black smokes.
This technology is exactly for thoroughly solving the problem and the clean-burning technology developed.
Summary of the invention
The technical problems to be solved in the utility model is that biomass fuel is applied to coal-burning boiler system, and for achieving the above object, the utility model takes following technical scheme:
A kind of is the clean burning system of firing block waste wood by coal-fired boiler reform, it is characterized in that hopper, compression roller and pot furnace bin are installed bottom fuel area density band successively, boiler body is connected with chimney with heat exchanger, exhaust pipe, dust separation system successively through pipeline, heat exchanger communicates with nozzle through secondary oxygen supplying tube, heat exchanger communicates with an air outlet through an ajutage, traveling-grate stoker is installed on the bottom of boiler body, one time air outlet is installed on below traveling-grate stoker, and nozzle is installed on above traveling-grate stoker.
The diameter of a described ajutage is 150 ~ 500mm.
