Description

Biomass boiler oxygenation strong-fire burnout device

Technical field

The utility model relates to a kind of boiler plant accessory, relates in particular to a kind ofly can make the fully burning of biomass fuel and coal, after-flame, raising boiler efficiency, and has and preserve the ecological environment and the remarkable biomass boiler oxygenation strong-fire burnout device of energy savings.

Background technology

Living beings belong to the renewable sources of energy, and fabulous comprehensive utilization prospect is arranged, and use the boiler technology of biomass fuel to obtain fast development, use living beings, ashes seldom, meet national energy-saving and environmental protection policy.Steam generator system burning design is very important, if design unreasonable, there are uncombusted fuel gas CO, H2, CH2 etc. in the combustion product, this part should the abundant after-flame release heat of secondary unburned discharges and enters atmosphere with flue gas, cause thermal loss, the blackness of exhaustion severe overweight had not only been wasted fuel but also contaminated environment.But existing product design and use aspect exists some shortcomings, does not establish secondary oxygenation burning device in the general body of heater, to making the living beings can not completing combustion in stove, this defective effect biomass-burning can source boiler use.Therefore, the utilization rate of biomass boiler has been subjected to great influence.

Summary of the invention

In order to overcome the volatile ingredient of existing conventional boiler biomass burning release cmpletely; cause thermal loss and problem of environmental pollution; the utility model technology provides a kind of can not only make living beings completing combustion, burnout, improve boiler efficiency, energy savings, protection environment; more meet comprehensive utilization policy and environmental regulation that country encourages to use the renewable sources of energy, promote the biomass boiler oxygenation strong-fire burnout device of boiler industry progress.

The technical solution of the utility model is achieved in that a kind of biomass boiler oxygenation strong-fire burnout device, comprise upper cover plate, base plate and be arranged on upper cover plate and base plate between the oxygenation chamber, offer port on the upper cover plate, the port bottom is provided with the taper wide-mouth of being made up of the oxygenation plate that has oxygenation hole, oxygenation plate bottom is connected with the poly-burner of the burner hearth of being made up of the taper fire board, the poly-burner of burner hearth is connected with air inlet on being opened in base plate, and the bottom of taper fire board is fixedly mounted in the base plate of intralamellar part outside the oxygen chamber along last;

The cavity that the oxygenation chamber is made up of oxygenation plate, taper fire board and oxygen chamber outside plate, the taper wide-mouth is communicated with the oxygenation chamber by the oxygenation hole that is arranged on the oxygenation plate, and the oxygenation chamber is in communication with the outside by the oxygen deliverng pipe interface that is arranged on the outside plate of oxygen chamber.

Described taper wide-mouth is the tapered channel of upper opening greater than lower openings.

The poly-burner of described burner hearth is the tapered channel of upper opening less than lower openings.

The utlity model has following good effect: the combustible gas that living beings are produced in boiler furnace has obtained the after-flame effect, has got rid of the biomass boiler over-emitting black exhaust.And improved the utilization rate of biomass energy, and increased the heat exchange amount, alleviated environmental pollution, not only energy-conservation but also environmental protection has promoted the technical progress of industry of biomass boiler, provides sound assurance to living beings comprehensive utilization equipment.

The specific embodiment

Shown in Fig. 1,2,3,4,5,6, a kind of biomass boiler oxygenation strong-fire burnout device, comprise upper cover plate 2, base plate 6 and be arranged on upper cover plate 2 and base plate 6 between oxygenation chamber 12, offer port 1 on the upper cover plate 2, port 1 bottom is provided with the taper wide-mouth of being made up of the oxygenation plate 10 that has oxygenation hole 3 11, oxygenation plate 10 bottoms are connected with the poly-burner 9 of the burner hearth of being made up of taper fire board 4, the poly-burner 9 of burner hearth is connected with air inlet 5 on being opened in base plate 6, and the bottom of taper fire board 4 is fixedly mounted in the base plate of outside plate 7 inside, oxygen chamber along on 8;

The cavity that oxygenation chamber 12 is made up of oxygenation plate 10, taper fire board 4 and oxygen chamber outside plate 7, taper wide-mouth 11 is communicated with oxygenation chamber 12 by the oxygenation hole 3 that is arranged on the oxygenation plate 10, and oxygenation chamber 12 is in communication with the outside by the oxygen deliverng pipe interface 13 that is arranged on the oxygen chamber outside plate 7.

Described taper wide-mouth 11 is the tapered channel of upper opening greater than lower openings.The poly-burner 9 of described burner hearth is the tapered channel of upper opening less than lower openings.

Living beings have formed unburnt CO, H at burner hearth through burning ₂, CH ₂Deng fuel gas, fuel gas enters the poly-burner of burner hearth by the air inlet that is opened on the base plate, the poly-burner of burner hearth absorbs from the temperature of burner hearth and heats the taper fire board, the oxygen that comes from the outside in the oxygenation chamber obtains adding the thermosetting high-temperature oxygen under the effect of taper fire board, after expanding, high-temperature oxygen enters the taper wide-mouth by the injection of the oxygenation hole on the oxygenation plate, unburnt fuel gas is with high-temperature oxygen mixing after-combustion and form the column of flame, the column of flame upwards expands under the effect of taper wide-mouth and ambient pressure, rotary combustion finally is fully burned in that second-time burning is indoor.

Installation site of the present utility model is positioned at the boiler furnace top, bottom, second combustion chamber.Living beings have formed unburnt fuel gas CO at burner hearth through burning, H2, CH2 etc. fully mix with the oxygen that oxygenation hole enters, will second-time burning, device has designed the poly-burner of burner hearth, temperature is very high, has formed high-temperature oxygen for the oxygenation chamber, and oxygen is forced oxygenation naturally from the oxygenation hole on the oxygenation plate, the intensity of a fire becomes the burning of eddy current rising type, the intensity of a fire is fierce, extreme temperatures, and combustible obtains after-flame cmpletely.Also can utilize secondary oxygenation control valve simultaneously, regulate oxygen feeding amount, control combustion-supporting high-temperature oxygen artificially and enter flow, thereby realize the best results of combustible component after-flame is regulated, thereby adapt to of the variation of multiple boiler to the burning optimum efficiency, the loss of also having saved heat energy has simultaneously prolonged the time of fuel combustion, easy operating easy to adjust relatively.Use the utility model technology combustible component to obtain abundant burning, promptly energy-conservation environmental protection has again reached each legislationss of environmental protection of the provisions of the relevant regulations issued by the State.
