Description

Biomass semi-coke heating stove

Technical Field

The utility model relates to a living beings blue charcoal heating stove.

Background

The existing boiler adopts a direct-fired structure, and the structure has great disadvantages of one: the hydroecium simple structure leads to the thermal efficiency poor. Because the heat absorption area of the combustion chamber is small, the heat in the combustion area is directly discharged from the upper part, and the heat absorption efficiency is greatly reduced. II, secondly: the structural design of discharging fume is unreasonable, leads to the fault rate height, and the potential safety hazard is many. The exhaust fan is easy to damage due to the fact that the exhaust fan is reinforced, the working environment is poor, the exhaust fan is used uninterruptedly and the like. Dust is accumulated near the exhaust fan in the using process, the flue is slowly blocked, smoke exhaust is not smooth, the air blower continuously works, burning flames are led to the opening of the material box, the final point fuel box accident is caused, and further serious accidents such as gas poisoning, house burning and the like are caused.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model provides a can make full use of heat to the blue charcoal heating stove of living beings of even heating.

The utility model provides a technical scheme that its technical problem adopted is:

a biomass semi-coke heating furnace comprises a furnace body, a material box, a material pusher, a water chamber and a combustion chamber, wherein the material box, the material pusher, the water chamber and the combustion chamber are arranged in the furnace body; and a smoke outlet is arranged above the back burning zone.

Furthermore, a plurality of water pipes communicated with the water chamber are arranged in the combustion chamber.

Furthermore, a mixer is arranged on the fire passing channel, the mixer comprises a fire discharging pipe and a horn-shaped collecting cover, the upper end of the collecting cover is fixedly connected with the water wall, and the lower part of the collecting cover is fixedly connected with the furnace bottom through a separation baffle; the fire discharging pipe is fixed behind the collecting cover, the center of the collecting cover is communicated with the fire discharging pipe, and a plurality of fire discharging holes are formed in the fire discharging pipe.

Further, the fire discharging hole is disposed below the fire discharging pipe. And a second ash removing port is arranged below the back burning zone.

The utility model has the advantages that:

through the back-burning structure, the heat absorption surface of the water chamber is increased by 40%, the heat efficiency is improved by 26%, the upper surface of the combustion chamber is totally closed, all heat is fully absorbed by the upper fire tube and the plate water layer, and then is guided to the back-burning zone from the lower surface under the action of the pressure difference of the smoke tube of the back-burning zone, and the residual heat passes through the plate water layer for secondary absorption, so that the heat absorption rate is greatly improved.

The reverse combustion area discharges fume naturally without a forced-draft fan: 1. the heat can not be pumped away, and the heat efficiency is greatly improved. 2. The dust directly falls into furnace, the burning bin accident that takes place because of the tobacco pipe blocks up can not appear, has greatly improved the security.

The back burning zone is carried again after the blender mixes the firework in with the combustion chamber, prevents that the burning zone both sides temperature is low, and middle temperature is high, is heated inhomogeneous problem.
