Abstract

The utility model provides a minitype indoor biomass smolder heating furnace, which comprises a furnace chamber enclosed by a furnace body with a thermal-insulating layer. The utility model is characterized in that the utility model is additionally provided with an air inlet with a regulating valve, an ash discharging port, a material feeding port, a chimney and a furnace cover covered on the material feeding port, wherein the air inlet, the ash discharging port, the material feeding port and the chimney are communicated with the furnace chamber; the chimney is positioned on one side of the top end of the furnace body, the air inlet is arranged on the upper end of the side wall of the furnace body far away from the chimney, the material feeding port is positioned on the top end of the furnace body, the ash discharging port is arranged on the lower end of the side wall of the furnace body and the ash discharging port position is plugged with an ash discharging sliding door. When users feed the material, the material needs compacting, and the whole surface except the ignition position is coated with smolder ash or combustion ash with a certain thickness, so that smolder can quickly form and develop stably. Compared with a coal burning furnace, the utility model has the advantages of economy, convenience and less content of sulfur dioxide; compared with a brazier and a combustion cell, the minitype indoor biomass smolder heating furnace can be used indoors, the smoke and the gas can be discharged via the chimney, the heat released by the smolder can be almost completely released indoors, the utility model has the advantages of remote possibility of fire-catching, high safety, high thermal efficiency, etc. The utility model is especially suitable for rural areas with abundant biomass.

Description

A kind of small indoor biological material hidden-burning heating stove

Affiliated technical field

The utility model relates to a kind of small indoor biological material hidden-burning heating stove, specifically, is to utilize biological material hidden-burning to be thermal source, is small-sized, the heating of house stove that heats in rural area dwelling house and the agricultural facility.

Background technology

Ancient Times in China brazier commonly used heats among a small circle, and the characteristics of brazier are the slow heat releases of glowing of applying biological matter, but because its fume emission indoor, is difficult to enlarge uses, and uncovered big, occurs naked light easily, enlarge use very dangerous.Propose to have occurred some in recent years in the northern country area in the paper of 1994 the 8th phases of " China's energy " magazine " work characteristics and the heat energy utilization analysis in the combustion pond " literary composition and be built in the underground combustion pond that is used to warm oneself of building, be mainly used in agricultural facility and rural area collective place (as middle and primary schools) etc., also there are some problems in the combustion pond at present, scatter and disappear in soil as the part heat, the thermal efficiency is low, and volume is big, and the construction trouble is manipulated also inconvenient.

The utility model content

The purpose of this utility model provide a kind of can overcome above-mentioned defective, volume little, easy to use, can deposit in the biological material hidden-burning heating stove indoor, that the thermal efficiency is high.Its technology contents is:

Comprise the furnace chamber that surrounds by the body of heater of being with heat-insulation layer, it is characterized in that: set up air inlet and ash discharging hole, spout, the chimney of the band control valve that is communicated with furnace chamber and cover bell on spout, wherein chimney is positioned at a side on body of heater top, air inlet is arranged on the upper end away from the sidewall of the furnace body of chimney, can control the size of furnace chamber air inlet by control valve, and then control biological material hidden-burning speed, spout is positioned at the top of body of heater, ash discharging hole is arranged at the lower end of sidewall of the furnace body, and the shutoff of ash discharging hole place has the ash discharge sliding door.

Described a kind of small indoor biological material hidden-burning heating stove, body of heater are positioned at the following bottom that reaches, air inlet center all around and are equipped with heat-insulation layer.

Described a kind of small indoor biological material hidden-burning heating stove, the bottom of body of heater is provided with footing, and the body of heater bottom surface is erected, and makes it not in contact with the ground, and heat is loose in indoor.

Described a kind of small indoor biological material hidden-burning heating stove, near biomass energy making ash discharging hole is fully glowed, the ash discharge sliding door is drawer type, inwall is provided with the heat-insulation layer suitable with inboard wall of furnace body thickness.

Its operation principle is: 1) with the living beings of drying, as crop material etc., put into furnace chamber from spout, compacting, bell is about 20 centimetres from the living beings charge level after the compacting, then, at living beings surface coverage about 5 centimetres glow ash or biomass fuel ashing, making like this glows can form fast, and stable development, need not cover the ash that glows at a fritter of reserving about 5 centimetres of 5 cm x near the air inlet place, as igniting place.2) the tate stalk is lighted in igniting, puts into stove igniting place, covers bell.3) regulate, wait the furnace wall to heat up after, can be according to required indoor or size that furnace wall temperature is regulated air inlet, in order to the adjusting speed of glowing.4) ash discharge, wait furnace wall cooling after, extract the ash discharge sliding door out, ash content is drawn out from going out ash discharging hole.

The utility model compared with prior art has following advantage:

1, economical, pollute little.It is fuel that warming stove adopts the living beings powder, compares with the warming stove that with the coal is fuel now, and economical convenient, content of sulfur dioxide is few in the product, especially is adapted to the abundant rural area of living beings.

2, safety, thermal efficiency height.Warming stove is placed on indoor, and flue gas is discharged by chimney, and the liberated heat that glows almost all is released in indoor, compares with brazier, is difficult for catching fire, and safety is compared thermal efficiency height with the combustion pond.

3, flexibly, convenient.Can design the warming stove of different volumes as required, also can according to weather maybe needs determine whether to use warming stove, with the combustion pond compare, the use aspect is very flexible.
