Abstract

The utility model discloses a reverse-combustion four-return stroke numerical control boiler, comprising a furnace body, a fire coal bin, a water pipe, a secondary combustion chamber, a forth-return stroke combustion channel, a gas outlet, and a fire pipe, wherein the fire coal bin is placed inside the furnace body and is communicated with the secondary combustion chamber through the water pipe, a lower part of the secondary combustion chamber is provided with an ash bin, and the secondary combustion chamber is communicated with a first return stroke combustion channel that is communicated with a secondary return stroke combustion channel through a pipe. The numerical control boiler is characterized in that a reverse-burning and reverse-combustion secondary combustion method is adopted and a high-temperature smoke-abating method is used to maker sure that thermal energy of fire coal is fully utilized and environment-friendly smoke abatement is realzied; a four-return stroke and multi-pipe cycle fire channel design is employed to fully absorb the thermal energy of the fire coal and to improve thermal utilization efficiency of the fire coal; thermal efficiency is enhanced to reach 85%; chimney discharge temperature is below 100 DEG C; and aims of smoke prevention, dust control, and environmental protection can be realized.

Description

The anti-four backhaul numerical control boilers that burn
Technical field
The utility model relates to a kind of numerical control boiler, relates in particular to a kind of anti-burning four backhaul numerical control boilers.
Background technology
Existing vertical boiler is generally the cylindrical shell and the inner bag of a cylinder cartridge type, and the bottom is a burner hearth, and top connects chimney and constitutes.The boiler thermal output of this kind structure is low, over-emitting black exhaust, chimney exhaust temperature high, is difficult for installing, seriously polluted.
The utility model content
The purpose of the utility model be to provide a kind of simple in structure, volume is little, makes combustion gas long flow path in stove, the thermal efficiency is high, oligosaprobic anti-burning four backhaul numerical control boilers.
The purpose of the utility model is realized by following mode: the counter four backhaul numerical control boilers that burn; Comprise body of heater, coal bunker, water pipe, secondary combustion chamber, four backhaul fire troughs, outlet flue, fire tube; It is characterized in that being provided with in the body of heater coal bunker; Coal bunker communicates with secondary combustion chamber through water pipe, and the secondary combustion chamber bottom is provided with cinder tank.
Said secondary combustion chamber communicates with a backhaul fire trough, and a backhaul fire trough communicates with the two return fire trough through pipeline.
Said two return fire trough communicates with three backhaul fire troughs through fire tube, and three backhaul fire troughs are communicating with four backhaul fire troughs through fire tube.
Said four backhaul fire troughs communicate with outlet flue through fire tube.
The beneficial features of the utility model is: adopt that backfire is counter burns second-time burning, utilize high temperature to eliminate smoke, coal-fired heat energy is made full use of reach environmental protection and eliminate smoke; Adopt the design of four backhaul multitube road circulation quirks; Fully absorb coal-fired heat energy, improve coal-fired heat utilization efficiency, improve the thermal efficiency and reach 85%; The chimney exhaust temperature can reach the purpose of smoke abatement and dust control, environmental protection in 100 degree.
