Description
Technical field
The utility model relates to a kind of kiln more particularly to a kind of multiple-energy-source fuel kilns.
Background technique
In the fusing of preparing ceramic clinker, crystallite frit and crystallite product frequently with horse-shoe flame furnace, horse-shoe flame furnace is with kiln
Flame is gained the name in shape of a hoof flowing, generally uses coal gas, fuel oil or natural gas as fuel.For coal gas kiln
Its air regenerator, gas regenerator, port and bocca and melting tank for mainly including commutator, being symmetrical set,
Air regenerator and gas regenerator realize the commutation of air and coal gas by commutator, and regenerative chamber, port, bocca are successively set
Be placed in the front end of melting tank, port merges combustion gas and combustion air premix to be sprayed into furnace pond through bocca, combustion gas and
Combustion air burns in melting tank provides heat for mixture；Fume afterheat can be absorbed in regenerator gas room and air regenerator
And preheating gas and combustion air are to improve flame temperature and save fuel；Port, bocca, regenerator gas room and air accumulation of heat
It is commutated in required time to prevent refractory material from crossing cause thermal damage alternately through the flue gas after coal gas, air and burning room.
Number of patent application CN201310480857.3 proposes a kind of fuel oil, the dual-purpose glass furnace port of coal gas, in pre-burning
The lower section of room (being equivalent to port) output end is equipped with fuel nozzle, which is connected to fueller and atomized fuel is pressed one
Determine angle to spray into bocca.
The kiln in fuel burning, abrogate by gas regenerator, and the gas that part is imperfect combustion is due to gas regenerator
Wall exosmoses or expands with heat and contract with cold, and easily flows backwards and enters gas regenerator, there are hidden peril of explosion.
Utility model content
The purpose of this utility model is that proposing a kind of multiple-energy-source fuel kiln, low calorie fuels gas-fired is not being used
When, combustion air is provided to gas regenerator, improves gas regenerator safety, while increasing the heat exchange volume of combustion air,
Kiln is set further to reach energy-saving and emission-reduction.
Multiple-energy-source fuel kiln described in the utility model, including commutator, symmetrically arranged air regenerator, coal gas store
Hot cell, port and bocca, melting chamber and exotic fuels nozzle, fuel gas with low heat value source by the first branch pipe and commutator into
Port connection, commutator gas outlet are connected to air regenerator, gas regenerator bottom respectively by pipeline, air regenerator,
It is connected at the top of gas regenerator with port first end, port second end is connected to by bocca with melting chamber, corresponding below port
Exotic fuels nozzle is arranged in bocca, further includes the second branch pipe, second branch pipe one end is connect with air gas source, the other end
It is connect with commutator air inlet.
Described, valve switch is equipped on the first branch pipe and the second branch pipe.Valve switch for control the first branch pipe and
The on-off of second branch pipe.
Use principle and process: when using low calorie fuels coal gas, exotic fuels nozzle be can be used simultaneously, and first
Valve switch on pipe is opened, and the valve switch on the second branch pipe is in an off state, provides combustion from the first branch pipe to diverter
Coal gas, coal gas are blended in port internal combustion burn through with the combustion air in air regenerator after gas regenerator preheats and cross flame
Mouth is melting chamber heat supply；When using high heating value fuel oil, the valve switch on the second branch pipe is opened, and the valve on the first branch pipe is opened
Shutdown, combustion air pass through combustion air, at this time gas regenerator effect and air accumulation of heat to gas regenerator through commutator
Room is identical, since, by air, the gas backflow that part can be prevented imperfect combustion enters gas regenerator in gas regenerator,
Gas regenerator safety is improved, while passing through combustion air accumulation of heat in gas regenerator of gas regenerator, increases and helps
The heat exchange volume for firing air, makes kiln further reach energy-saving and emission-reduction.
Described, the first branch pipe is equipped with booster fan.Booster fan supplies combustion air with to the second branch pipe.
The beneficial effects of the utility model are: providing combustion air to gas regenerator in fuel burning, coal gas is improved
Regenerative chamber safety, while increasing the heat exchange volume of combustion air, so that kiln is further reached energy-saving and emission-reduction.

In figure: 1, commutator；2, air regenerator；3, gas regenerator；4, port；5, bocca；6, melting chamber；7, high
Combustion value fuel nozzle；8, the first branch pipe；9, the second branch pipe；10, valve switch；11, booster fan.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, multiple-energy-source fuel kiln described in the utility model includes commutator 1, symmetrically arranged air storage
Hot cell 2, gas regenerator 3, port 4 and bocca 5, melting chamber 6, exotic fuels nozzle 7 and the second branch pipe 9, fuel gas source
It is connect by the first branch pipe 8 with commutator air inlet, commutator gas outlet is stored with air regenerator 2, coal gas respectively by pipeline
The connection of 3 bottom of hot cell, air regenerator, gas regenerator top are connected to 4 first end of port, and port second end passes through bocca
