Description
Technical field
The utility model is related to energy conversions, and in particular to biomass fuel hot air stove.
Background technology
Boiler is the equipment that the chemical energy of fuel is converted to thermal energy, usually requires to be passed through thereto in fuel combustion and help
Combustion gas, the usually air containing oxygen.In order to make fuel fully burn as possible, it is usually passed through excessive air, but air
After being largely passed through, the temperature of fuel can be caused to reduce, influence the burning of fuel on the other hand, influence the conversion of energy.But
It will directly help to be passed into again in furnace chamber after gas heating and need a large amount of energy in this way, and improve cost, it is a kind of to solve the problems, such as this
New biomass fuel hot air boiler is even more important.
Utility model content
The purpose of this utility model is to provide a kind of biomass fuel hot air stoves, solve fuel and low temperature in the prior art
Help combustion gas mixing that fuel is made to be difficult to clean-burning problem.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of biomass fuel hot air stove, including furnace chamber and the heat exchanger positioned at furnace chamber top are arranged on the furnace chamber
There are fuel inlet and exhanst gas outlet, cold air inlet and heat outlet with air communication are provided on the heat exchanger, it is described
Isocon is installed at exhanst gas outlet or heat outlet at least one, the isocon is connected to fuel inlet.
Biomass fuel hot air stove in the application is low to avoid combustion-supporting temperature from spending, and causes fuel that cannot fully burn,
By heat extra in heat outlet and combustion gas mixing is helped, to improve the temperature of combustion-supporting gas, allows the fuel to fully burn.Tool
Body is in use, pressure-regulating device can be installed at heat outlet, according to production needs, by the pressure adjusting at heat outlet
To suitable value, remaining hot wind is passed through by isocon from fuel inlet, mixed with the new combustion-supporting gas of low temperature while being passed through
It closes.
Pressure at heat outlet is just met for that production needs or the insufficient pressure of remaining hot gas is with by the temperature of combustion-supporting gas
Degree is increased to designated value, can partial fume that smoke outlet leaves and low temperature be helped combustion gas mixing at this time, improved combustion-supporting
The temperature of gas.
Since the combustion-supporting component contents such as oxygen in flue gas are less, so preferentially selecting the heat that will not be utilized at heat outlet
Gas returns to furnace chamber and is continuing with, and when hot gas is it is impossible to meet needing, can just reuse flue gas.
Preferably, being enclosed with more than two gas circulation layers, the gas on the outside of the furnace chamber successively from inside to outside
The layer that circulates includes exhaust gases passes and pre- hot gas path, and the exhaust gases passes are connected to exhanst gas outlet, and preheater channel enters with cold air
Mouth connection.
As much as possible to improve the utilization rate of flue gas, using remaining flue gas after heat exchange to the gas in heat exchanger
It is preheated.Exhaust gases passes and preheater channel are equivalent to cover and impinge upon on furnace chamber, and contact area is big, and heat exchange efficiency is high.
Preferably, the exhaust gases passes and pre- hot gas path at least one there are two more than, and exhaust gases passes and
Pre- hot gas channel spacing setting, is interconnected between two neighboring exhaust gases passes or pre- hot gas path.
Theoretically, the time that flue gas and cold air flow in exhaust gases passes and preheater channel is longer, and heat exchange efficiency is got over
Height, but the cost of equipment can also increase, it is possible to as needed, select the quantity of exhaust gases passes and pre- hot gas path.
Preferably, the pre- hot gas path there are two more than, leads between two gases circulation layer of furnace chamber
Cross the heat exchanger connection.
Cold air preheating after enter heat exchanger in, carry out heat exchange after from most close to the gas of furnace chamber circulation layer in from
It opens, can further heat at this time.
Preferably, being provided with type dust arrester in the furnace chamber, the type dust arrester includes that one end is fixed by elastic strip
Dust-break net on furnace chamber inner wall.
Biomass fuel boiler and oil-burning gas-fired boiler are different, some ash contents are will produce in combustion process, to avoid these
Ash content accumulates in the boiler, influences the heat exchange efficiency of boiler, needs to be fallen as possible in furnace cavity bottom, then from furnace cavity bottom
Ash outlet leaves.
Dust-break Netcom crosses elastic strip and is connected on boiler inner wall, when dust-break falls the ash content of constant weight on the net, dust-break
Side of the net far from elastic strip can tilt down, and grey branch thereon automatically falls off.
Preferably, the dust-break net and elastic strip radially tilt gradually downward from inside to outside along furnace chamber, the dust-break
Percussion device is fixed on device, the percussion device includes impacting tube and can be hit along what furnace chamber radially slided in impacting tube
Batting.
Due to the lighter in weight of ash content itself, and elastic strip deforms upon relatively soft, and ash content is slided on the net from dust-break
The effect fallen may be bad, so impact bead is arranged on type dust arrester, impact bead is located at close to furnace chamber wall under normal circumstances
Side, when ash content runs up to constant weight, dust-break net can move down, and impact bead can slide down under gravity
Side far from furnace chamber wall, ash content slide under the action of shock, and the then online pressure reduction of dust-break can be moved up, be hit
Batting can be slided into again close to the side of furnace chamber wall, self-return.
Elastic strip therein can make spring, can also be the sheet metal for having certain toughness, specifically also need to according in stove
Temperature and the selection of boiler size.
Compared with prior art, the beneficial effects of the utility model are at least one of following：
Hot gas or flue gas are returned into burner hearth and re-use preheating therein, improves the efficiency of combustion of fuel.
Type dust arrester can stop most of ash content, reduce the adverse effect of the ash content exchange thermal efficiency.
