Abstract
The utility model relates to a fuel non-reversing regenerative burning device, especially being suitable for a metallurgy furnace. The utility model is characterized in that two common combustion supporting emitting vents use the same fuel nozzle; the fuel nozzle sprays fuel continuously without switching and runs without stopping, so as to reach the purposes that: 1, the fuel spraying has no switching and the reversing control equipment has less speed loss and the operation is easy; 2, the problem that once the fuel reversing is closed and the fuel nozzle stops providing fuel, the remained fuel is heated to decompose and coke to cause a jam of the fuel nozzle is solved.
Description
The utility model relates to a kind of no-fuel-switch heat accumulating burner capable, is specially adapted to the heat accumulating burner capable of metallurgical industry furnace.
Be energy savings, improve the industrial furnace thermal efficiency, the many industrial furnaces of China adopted heat storage type combustion method promptly in recent years: a burner is formed in a fuel nozzle ports, combustion air, the public import and export of flue gas.Two burners use in pairs, the commutation alternation, and one of them burner ejection fuel, combustion air is in the burning phase, takes away the heat that heat storage is accumulated; Another burner is in the smoke evacuation phase, and heat storage is accumulated heat.Its shortcoming and defect part is: when fuel did not need through heat storage switching preheating, two fuel nozzle ports need be in company with combustion air, flue gas spout commutation alternation.That is: burner is in burning during the phase, opens the fuel nozzle ports by-pass valve control and supplies with fuel; Burner is in the smoke evacuation accumulation of heat during phase, closes the fuel nozzle ports by-pass valve control, stops to supply with fuel.Because of the fuel switching causes following problem: 1. full stove commutation control appliance complexity, require control accurate, reliable, the operating technology difficulty is big.2. when fuel nozzle ports was in closed condition, residual fuel decomposes, coking caused fuel nozzle ports to stop up, and influence the ordinary production of fuel apparatus system stable operation and stove.
Be to solve the problem that above-mentioned heat accumulating burner capable commonly used exists order of the present utility model, thereby a kind of new no-fuel-switch heat accumulating burner capable is provided.
Order of the present utility model ground is realized in the following way: two public combustion airs, smoke entrance, the shared fuel nozzle ports burner that partners.Fuel nozzle ports sprays fuel continuously, need not to switch non-stop run.Two public combustion airs, smoke entrance air feed, burning, smoke evacuation alternation.Thereby accomplish: fuel does not have switching, makes the commutation control appliance reduce, and is simple to operate.Solved because the fuel commutation is closed, and fuel nozzle ports stops to supply with during the fuel, residual fuel decomposes, coking cause the fuel nozzle ports blockage problem.
The advantage of the utility model heat storage type combustion mode is:
1. fuel does not have switching, and reversing control system equipment is simple, small investment, and operation and maintenance cost is low.
2. stable equipment operation is reliable, the efficiency of combustion height, and incomplete combustion loss is few.
3. can weigh inferior fuels such as residual oil with high viscosity.
Adopt the utility model and heat storage type combustion method comparison commonly used can obtain following economic benefit:
1. minimizing equipment investment reduces the maintenance of equipment expense, a medium-sized heating furnace, and ten thousand yuan of 30-50 can reduce cost in year.
2. stable equipment operation is reliable, and stove production operational availability height increases steel output, can increase by ten thousand yuan of economic benefit 20-30 in 1 year.
Fig. 1 is a heat accumulating burner capable structure chart commonly used.
Fig. 2 is the utility model no-fuel-switch heat accumulating burner capable structure chart.Among the figure: (1), (4) are combustion air, exhanst gas outlet; (2), (5) are heat storage; (3), (6) are fuel nozzle ports.
Below in conjunction with accompanying drawing the utility model is said usefulness in detail:
Fig. 1: be heat accumulating burner capable commonly used, a burner is formed in (1), (2), (3) among the figure, and another burner is formed in (4), (5), (6) among the figure, two burners use in pairs, alternately commutation work, one of them burner is in burning during the phase, and another burner is in the smoke evacuation heat absorption phase.
Fig. 2: be the utility model no-fuel-switch heat accumulating burner capable, (2) are two combustion air spouts among the figure, (1), (4) are heat storage, alternation commutates for two shared combustion airs, smoke entrance (1), (4), a shared fuel ejiction opening (3), the burner that partners, fuel nozzle ports sprays fuel continuously, does not have to switch, work incessantly.
Claims (2)
1. no-fuel-switch heat accumulating burner capable is characterized in that: (1), (4) shared fuel nozzle ports (3) are imported and exported in two shared combustion airs, smoke evacuations.
2. do not bribe heat accumulating burner capable according to right with 1 described not changing, it is characterized in that fuel nozzle ports (3) sprays fuel continuously and do not have switching, continual work.
