Abstract

The utility model relates to a combustion fire spray device, in particular to an oxygen-replenishing biomass combustion furnace. The oxygen-replenishing biomass combustion furnace comprises a furnace hearth (2), a hopper (1) and a flame nozzle (3) are arranged at the waist of the furnace hearth (2), and an air inlet is arranged at the bottom; the furnace hearth (2) is located within a temperature-resisting shell (4); an air cooling cavity (5) for the entrance of flowing air is formed between the furnace hearth (2) and the temperature-resisting shell (4); and an oxygen-replenishing hole (7) communicated with the air cooling cavity (5) is arranged on the flame nozzle (3). Flowing air is used for cooling and insulating the wall of the furnace hearth, the heat loss of the furnace hearth can be greatly reduced, and the heat energy utilization efficiency of a biomass combustor is greatly increased. Oxygen is replenished to the flame nozzle through the oxygen-replenishing hole, so that non-combusted air is fully combusted, and the combustion efficiency of fuel is increased.

Description

A kind of oxygenating biomass combustion stove
Technical field
The utility model relates to a kind of burning flame equipment, relates in particular to a kind of oxygenating biomass combustion stove.
Background technology
Biomass fuel is a kind of with the tangerine bar, and wood chip, organic domestic waste etc. be through screening, oven dry, and a series of ways such as extrusion modling and a kind of New-type fuel of making, what this kind fuel used all is some discarded objects, so biomass fuel is a kind of fuel of environmental protection.
Biomass burner is a kind of burner that is used for firing biomass fuel specially, and this burner has the efficiency of combustion height, effective advantage.But biomass combustion in the market generally all is to use on boiler plant; Traditional biomass burner flue need use water-cooled; Account for 15% of total amount of heat because the heat that water-cooling system causes is failed to keep an appointment,, but also wasted precious water resource so the heat energy service efficiency is very low.
Biomass fuel during gasification, and combustion, often because the air inlet oxygen supply is not enough, makes fuel combustion insufficient in burner hearth, causes waste of fuel on the one hand, has discharged pernicious gas on the other hand, and is unfavorable to environment.
The utility model content
The utility model provides a kind of oxygenating biomass combustion stove, and its heat energy service efficiency is high, and fuel combustion is abundant.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of oxygenating biomass combustion stove comprises burner hearth; Said burner hearth waist is provided with hopper and flame hole, and the bottom is provided with air inlet; Said burner hearth is positioned at the heatproof shell; Form the air cooling chamber that can feed moving air between said burner hearth and the heatproof shell; Have the oxygenating hole that is connected with the air cooling chamber on the said flame hole.
The beneficial effect of the utility model is: it is heat insulation to adopt moving air that hearth wall is cooled off, and can reduce the loss of burner hearth heat greatly, makes the heat energy service efficiency of biomass burner greatly improve; To the flame hole supplemental oxygen, making does not have the full combustion of gas of burning, has improved fuel economy through the oxygenating hole.
Description of drawings
Fig. 1 is the structural representation of a kind of oxygenating biomass combustion of the utility model stove;
Fig. 2 is the partial enlarged drawing of A part among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of oxygenating biomass combustion of the utility model stove is made detailed description:
As shown in Figure 1, this oxygenating biomass combustion furnace main body is a burner hearth 2, is the hollow cavity of a cylinder type, adopts resistant to elevated temperatures special material to process, and is at high temperature indeformable, not oxide etch.The waist of burner hearth 2 is provided with a hopper 1 near the position at top, in order in burner hearth 2, to carry biomass fuel.Offer a flame hole 3 on the relative waist of burner hearth 2 and hopper 1, the flame of burner hearth 2 internal combustion is used from flame hole 3 ejections again.Air inlet 6 is offered in the bottom of burner hearth 2, adopts mode or other modes delivering oxygen in burner hearth 2 of natural aspiration.
Burner hearth 2 whole placing within the heatproof shell 4 cylindraceous, heatproof shell 4 and burner hearth 2 concentric settings form a circular air cooling chamber 5 between heatproof shell 4 and the burner hearth 2.Bottom-up feeding has moving air in the air cooling chamber 5.
As shown in Figure 2, the bottom of flame hole 3 has the oxygenating hole 7 of a circle, and oxygenating hole 7 is communicated with the inside and the air cooling chamber 5 of flame hole 3.
When this oxygenating biomass fuel burner is done, send into biomass fuel from hopper 1 and get in the burner hearth 2, through ignition, flame outwards sprays from flame hole 3, is used.Feed moving air in the air cooling chamber 5, the heat that burner hearth 2 distributes is taken out of through moving air, has cooled off burner hearth 2 walls on the one hand, and heat can not be delivered to heatproof shell 4 on the other hand, plays effect of heat insulation.It is heat insulation to adopt moving air that burner hearth 2 walls are cooled off, and can reduce the loss of burner hearth 2 heats greatly, makes the heat energy service efficiency of biomass burner greatly improve.Biomass fuel is in burner hearth 2 during gasification, and combustion; Because air inlet 6 oxygen supplys are not enough, can make that fuel combustion is insufficient, oxygenating hole 7 is with in the input of the air in the air cooling chamber 5 flame hole 3; Making does not have the full combustion of gas of burning, has improved the efficiency of combustion of biomass combustion.

Claims (1)
