Abstract

A special boiler for biomass fuel, which is provided, relates to a boiler which is divided into three parts, namely, an upper body of the boiler, a lower body of the boiler and a boiler base, wherein, the upper body of the boiler is divided into an inner jacket and an outer jacket; water is held between the jackets; the inner jacket is connected with the heating water pipe by passing through the pipe inside which the water is held and a flame path combustion chamber is arranged at the outer wall of the pipe; the lower body of the boiler is a gas producing chamber and divided into an inner jacket and an outer jacket with water held between the jackets; the upper body and the lower body are communicated with connection water pipes of the upper body and the lower body; the boiler base is at the bottom of the furnace and internally provided with a primary wind chamber the upper end of which is provided with a furnace grill; the furnace grill consists of two layers of square steel bars which are intercrossed with each other and fuel is placed on the surface of the furnace grill. The fuel is treated with stratified combustion in the furnace body and the gas after being produced is directly burned with thorough and safe combustion. The boiler is characterized by no black smoke in the chimney, no waste of heat energy, environmental protection and energy conservation.

Description

Biomass fuel is boiler dedicated

Technical field

The utility model relates to a kind of boiler, and it is boiler dedicated particularly to relate to a kind of biomass fuel.

Background technology

Living beings belong to renewable resource, and biomass energy belongs to regenerative resource owing to can regenerate by photosynthesis of plants together with wind energy, solar energy etc., and aboundresources can guarantee the continuous utilization of the energy; Sulfur content, the nitrogen content of living beings is low, generate in the combustion process SOX, NOX are less; When living beings act as a fuel,, can alleviate greenhouse effects effectively when growth because the carbon dioxide that it needs is equivalent to the amount of the carbon dioxide of its discharging, thereby is similar to zero to the clean discharge capacity of the carbon dioxide of atmosphere; Biomass fuel distributes very wide, and the region lacking coal can make full use of biomass energy; It is mainly used in biogas, compression forming solid fuel, gasification production combustion gas, gasifying electricity generation, production fuel alcohol, thermal cracking production biodiesel etc.The boiler firing rate of existing biomass fuel boiler is slow.Must replenish steam in order to improve combustion gas output, take external steam source of the gas to solve usually.Carbon monoxide can not fully burn, and also can pollute environment.

Summary of the invention

It is the boiler of fuel with living beings that the purpose of this utility model is to provide a kind of, this boiler is connected in one with generation chamber and combustion chamber, make generation chamber not produce malleation, its fire grate is made up of the two-layer square bar that intersects in length and breadth up and down, fuel is stratified combustion in body of heater, and its sufficient combustion, safety have not over-emitting black exhaust of chimney, heat is not wasted, the characteristics of environmental protection and energy saving.

The purpose of this utility model is achieved through the following technical solutions:

Biomass fuel is boiler dedicated, and this boiler is divided into boiler upper body, boiler lower body and boiler foundation three parts, and the upper body is divided into inside and outside cover, inner room dress water, and interior cover poling connects, and is subjected to be water in the pipe of hot-water line, and the pipe outer wall is the quirk combustion chamber; Lower body is the combustion gas generation chamber, and upper and lower body connects water pipe by last lower body and is connected, and lower body is divided into inside and outside cover, inner room dress water; Bottom of furnace body is boiler foundation; Be provided with air compartment in the stove one time, air compartment upper end be a fire grate, and fire grate is made up of the two-layer square bar of intersection in length and breadth up and down, places fuel above the fire grate.

Aforesaid biomass fuel is boiler dedicated, and its boiler upper body is equipped with boiler delivery port, chimney, atmosphere connection interface; The boiler lower body is equipped with blowoff valve, secondary wind standpipe, backwater interface and a fire door, an ash door.

Advantage of the present utility model and effect are:

1. the utility model is connected in one with generation chamber and combustion chamber, make generation chamber not produce malleation, its fire grate is provided with the square bar of two-layer intersection up and down, be used for the burning of biomass fuel, fuel is stratified combustion in body of heater, makes its sufficient combustion, safety, has not over-emitting black exhaust of chimney, heat is not wasted, the characteristics of environmental protection and energy saving.

2. the utility model is fuel with living beings, and SOX, NOX that sulfur content, the nitrogen content of living beings is low, generate in the combustion process are less; The clean discharge capacity of the carbon dioxide of atmosphere is similar to zero, can alleviates greenhouse effects effectively.

Description of drawings

Accompanying drawing is the utility model overall structure schematic diagram.

The specific embodiment

With reference to the accompanying drawings the utility model is elaborated.

As shown in the figure, the utility model is partly formed by three, and first is boiler upper body 6 partly; Second is boiler lower body 16 partly; The 3rd partly is boiler foundation 1.The upper body is divided into inside and outside cover, middle dress water, and interior cover poling connects, and is subjected to leak water in the pipe of hot-water line 7, and the pipe outer wall is quirk combustion chamber 11, and the upper body is equipped with boiler delivery port 8, chimney 9, atmosphere, and to be communicated with interface 10 lower bodies be combustion gas generation chamber 12.Upper and lower body is gone up lower body connection water pipe 5 by two and is connected, lower body is divided into inside and outside cover, middle dress water, lower body are equipped with blowoff valve 15, secondary wind standpipe 13, backwater interface 2 and fire door 4, an ash door 3, and fire grate 18, a solar or lunar halo and a secondary solar or lunar halo are arranged at the bottom.Fire grate 18 is made up of the two-layer square bar that intersects in length and breadth up and down, the width between per two square bars and the length of side of square bar are 16mm, and secondary solar or lunar halo is delivered to lower body top with wind, and one time solar or lunar halo is sent wind into bottom of furnace body, bottom of furnace body is boiler foundation 1, can establish the retaining ash removal pool in the basis.The utility model drops on the basis after boiler is made up, cistern is piled water, waterborne is an air compartment 17, one time the air compartment upper end is a fire grate, free 14 igniting of material fuel above the fire grate, its principle is: during fuel combustion, produce carbon monoxide, carbon monoxide is gone to the zonal combustion of secondary wind, enters the boiler upper body and fully burns, after the fire in a stove before fuel is added burnouts above the fire grate, after ashes fall into the water and produce steam and enter the furnace bottom fire and mix, make furnace bottom be in the anoxycausis state and increase the generation of carbon monoxide, fully burn at secondary wind upper end carbon monoxide like this, make chimney not arrange black smoke, reach the optimum state of biomass fuel combustion.
