Abstract
A petroleum coke powder stable-flame burner consists of high-temperature preheating tubes; the temperature of the primary air of the petroleum coke powder passing through the high-temperature preheating tubes basically reaches the ignition temperature of the petroleum coke powder, and the primary air of the petroleum coke powder can be directly sprayed towards a black furnace for ignition and combustion, so that the problem that the petroleum coke powder cannot be directly ignited for combustion in an industrial furnace due to the low volatile matter and difficult ignition is solved. The petroleum coke is an industrial byproduct, has high combustion value and low ash content, can be conveyed conveniently, and has very wide fuel using space. The petroleum coke powder stable-flame burner has the advantages of reliable ignition and stable combustion, can replace fuel gas or fuel oil to be widely applied to industrial furnaces, and has remarkable economic benefit.
Description
Affiliated technical field
The utility model relates to a kind of petroleum coke powder stable flame combusting device, especially the petroleum coke powder stable flame combusting device is made up of the high temperature preheating pipe, temperature behind a wind process of the petroleum coke powder high temperature preheating pipe reaches the ignition temperature of petroleum coke powder substantially, can directly expect to light a fire and burn, solve because petroleum coke powder fugitive constituent low ignition difficulty and problem that can not direct-fire burning in industrial furnace.Because the price of petroleum coke unit's calorific value is done fuel but well below heavy oil with petroleum coke powder, and very big economic benefit and social benefit are arranged.
Background technology
The calorific capacity height of petroleum coke, ash content is low, price is low, possesses primary condition as industrial fuel, but the fugitive constituent of petroleum coke powder is very low, the igniting ratio of specific heat that needs of catching fire is higher, ignition difficulties, required time of petroleum coke powder after-flame is long, because the restriction of these factors becomes very difficulty or even impossible thing with petroleum coke power combustor direct-fire burning, cause petroleum coke powder direct application in industry to be subjected to very big restriction as burner fuel, at present, this combustion system only is confined in the production of glass furnace.
Summary of the invention
For overcome petroleum coke powder can not be as heavy oil the problem of direct-fire burning, the utility model provides a kind of petroleum coke powder stable flame combusting device.This petroleum coke powder stable flame combusting device is low at the petroleum coke powder fugitive constituent, ignition difficulties, be difficult for catching fire, problems such as the tail-off time is long, designed special high temperature preheating pipe, make wind of petroleum coke powder before entering the combustion chamber, in the high temperature preheating pipe, carry out abundant preheating, the petroleum coke powder particle has obtained effective thermal activation, enter into the combustion chamber by the petroleum coke powder nozzle again through the petroleum coke powder after the abundant preheating, with fully burn after the high temperature combustion air of high temperature combustion air nozzle ejection mixes, solved the petroleum coke powder ignition difficulties, the problem of combustion instability.
The technical scheme that its technical problem that solves the utility model adopts is: design has the high temperature preheating pipe in the petroleum coke powder stable flame combusting device, wind of petroleum coke powder carries out Hybrid Heating at high temperature preheating Guan Zhongyu high-temperature flue gas, make wind-warm syndrome degree of mixed petroleum coke powder reach the petroleum coke powder ignition temperature rapidly, enter into the combustion chamber by the petroleum coke powder nozzle again through the wind of petroleum coke powder behind the high temperature preheating pipe, carry out mixed combustion with the high temperature combustion air of high temperature combustion air nozzle ejection, reach clean-burning purpose.
The beneficial effects of the utility model are: it is low to have solved the petroleum coke powder fugitive constituent, ignition difficulties, problem that can not smooth combustion in burner.When the petroleum coke powder stable flame combusting device burns, wind of petroleum coke powder is through the high temperature preheating of high temperature preheating pipe, make petroleum coke powder before entering into the combustion chamber, reach the temperature of petroleum coke powder burning-point substantially, in the combustion chamber, carry out efficient mixed combustion with the high temperature combustion air of high temperature combustion air nozzle ejection again.Because the cost of petroleum coke powder will reduce much than combustion gas and fuel oil under the situation of equal heat, and petroleum coke powder stable flame combusting device flameholding, the flame temperature height, combustion product cleans substantially, adopts the petroleum coke powder new combustion techniques that energy-conserving and environment-protective are of great importance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model principle schematic.
Among Fig. 1,1, the petroleum coke powder stable flame combusting device, 2, the combustion chamber, 3, the high temperature preheating pipe, 4, the petroleum coke powder nozzle, 5, high temperature combustion air nozzle.
Specific embodiments
During the work of petroleum coke powder stable flame combusting device, wind of petroleum coke powder carries out abundant Hybrid Heating at high temperature preheating Guan Zhongyu high-temperature flue gas, after the Hybrid Heating, wind-warm syndrome degree of petroleum coke powder has reached the ignition temperature of petroleum coke powder basically, wind of petroleum coke powder enters into the combustion chamber through the petroleum coke powder nozzle, efficiently mix after-combustion with the high temperature combustion air of high temperature combustion air nozzle ejection, reach steady flame and clean-burning purpose at last.
