Description
Technical field
The present invention relates to biomass boiler technology field, particularly a kind of method for improving biomass boiler efficiency of combustion.
Background technology
Biomass boiler is a species of biomass boiler, be exactly with biomass energy as fuel boiler biology
Matter boiler, is divided into biomass steam boiler, biomass hot water boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical biology
Matter boiler, horizontal biomass boiler etc..
At present, during the blowing system of biomass boiler is blowing (i.e. once dry path) from bottom to top, air
Oxygen almost exhausts when the entrance of combustion chamber is combustion-supporting for biomass fuel, and biomass fuel meeting after combustion chambers burn
Substantial amounts of flammable volatile matter is produced into combustion chamber top (burner hearth), at this moment the oxygen wretched insufficiency in burner hearth, makes flammable volatilization
Dividing fully to burn, and on the one hand cause energy waste, on the other hand cause pollution of the discharge gas to air.
Because burning gradually develops after coal powder ignition, burning institute liberated heat is more than heat output, so flue-gas temperature is not
Disconnected rise, thus form a region that burning is rapid, temperature is higher.Heat is released most in the region.Commonly referred to as this area
Domain is flame kernel（Or combustion centre）.The center of combustion centre often bias combustion room, can cause water storage in a combustion chamber
Room it is heated uneven, and burn and uneven can reduce the efficiency of combustion of combustion chamber.
The content of the invention
The technical problem to be solved in the present invention is that there is provided one kind raising biomass boiler for above-mentioned the deficiencies in the prior art
The method of efficiency of combustion, the air distribution of angle adjustable is carried out to boiler furnace, and whirlwind runner is formed in combustion chamber, is realized uniform
Burning, so as to improve efficiency of combustion.
In order to solve the above technical problems, the technical solution used in the present invention is：One kind improves biomass boiler burning effect
Set in the method for rate, including boiler body, boiler body in combuster, the combustion chamber and be provided with blowing system, this is matched somebody with somebody
Wind system includes air distribution pipeline and blower fan；Some heat energy that heat energy monitoring is carried out to whole combustion chamber are provided with the combustion chamber
Detector, is provided with a processor and is electrically connected with the heat energy detector and blower fan；The air distribution pipeline is included around burning
Main pipeline and the secondary pipeline that is connected with the main pipeline that chamber interior walls are set, the end of this pipeline is by angle demodulator with matching somebody with somebody
Tuyere is connected, the adjustable angle with tuyere；Temperature Distribution in the heat energy detector detection combustion chamber, passes through the number of processor
After being handled according to change, combustion chamber internal ratio mean temperature is higher by the burning point of preset value as the center of whirlwind runner, air distribution is adjusted
Whirlwind runner is formed in the range of the certain radius at the angle Shi Yigai centers of mouth.
In above-mentioned technical proposal, air is entered by air compressor before the air of the blower fan enters air distribution pipeline
Row compression.
In above-mentioned technical proposal, the bottom in the combustion chamber is provided with the combustion-supporting net that timing is tilted.
The beneficial effects of the invention are as follows：
1st, overall structure is simple and compact, and blowing system is in the air distribution pipeline and real-time detection combustion chamber of adjustable angle
Heat energy distribution, so as to adjust angle demodulator by processor, enables with tuyere in time with bias combustion room combustion centre
Burning carries out air distribution adjustment, makes to realize homogenous combustion in whole combustion chamber.
2nd, the maximum temperature point in the combustion chamber detected using heat energy detector is combustion centre（Generally and mean temperature
Differing distribution is great）, the center using the combustion centre to form whirlwind runner, using the certain distance of the combustion centre as radius
Runner circle is formed, the angle adjustment with tuyere is tangent with the runner circle.Burning can be improved by carrying out air distribution using compressed air
Indoor oxygen content, improves efficiency of combustion.
3rd, for the comburant of coal charge etc, stacked together due to feeding the comburant made, influence whether the effect of burning
Rate, using can timing tilt combustion-supporting net, comburant can be dug, allow flowing air can fully with bottom comburant
Contact, improves the efficiency of burning.
