Summary of the invention
Technical problem to be solved in the utility model is: a kind of combusting coal water slurry and natural gas hybrid boiler are provided, solve the narrower defective of the scope of application of boiler of the prior art, increase the scope of application of boiler.
The technical scheme that the utility model provides is, a kind of combusting coal water slurry and natural gas hybrid boiler, comprise body of heater, water coal slurry burner, smoke wall and convection bank, be provided with the combustion chamber in described body of heater, a side that is positioned at described combustion chamber in described body of heater is provided with described smoke wall and described convection bank, also comprises gas burner; Described gas burner and described water coal slurry burner are separately positioned on the front wall of described combustion chamber.
The hybrid boiler of combusting coal water slurry as above and natural gas, in order to put easily coal water slurry fired burner after lighting gas burner, described gas burner is arranged on the below of described coal water slurry fired burner.
The hybrid boiler of combusting coal water slurry as above and natural gas, in order to put more effective, more accurately coal water slurry fired burner, described gas burner center line should be parallel with described coal water slurry fired burner center line.
The hybrid boiler of combusting coal water slurry as above and natural gas, in order to facilitate to the gas burner transport gas, described gas burner inside is installed with the natural gas trunk line, described natural gas trunk line one end and outside natural gas line link together, and the other end is installed with the gas burner nozzle.
The hybrid boiler of combusting coal water slurry as above and natural gas, in order conveniently to light gas burner, described gas burner nozzle place is provided with igniter.
The combusting coal water slurry that the utility model provides and natural gas hybrid boiler, by add gas burner on the front wall of combustion chamber, make boiler from adopting single water-coal-slurry to act as a fuel, become simultaneously metabolic water coal slurry and coal gas or the Mobyneb boiler of metabolic water coal slurry or coal gas separately, increased the scope of application of boiler.By adding gas burner, solved the defective that existing boiler can only use water-coal-slurry to act as a fuel; By gas burner being arranged on the below of water coal slurry burner, can put easily coal water slurry fired burner after lighting gas burner; By making the gas burner center line parallel with the coal water slurry fired burner center line, can put more effective, more accurately coal water slurry fired burner; By in gas burner inside, the natural gas trunk line being set, can be easily to the gas burner transport gas; By at gas burner nozzle place set-point firearm, can light easily gas burner
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do one to the accompanying drawing of required use in embodiment or description of the Prior Art and introduce simply, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of the hybrid boiler embodiment of the utility model combusting coal water slurry and natural gas.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the hybrid boiler of the present embodiment combusting coal water slurry and natural gas, comprise body of heater 1, water coal slurry burner 2, smoke wall 3 and convection bank 4, be provided with combustion chamber 5 in body of heater, a side that is positioned at combustion chamber 5 in body of heater 1 is provided with smoke wall 3 and convection bank 4, also comprise gas burner 6, gas burner 6 and water-coal-slurry combustion 2 burners are separately positioned on 5 front walls of combustion chamber.
Particularly, add gas burner 6 on the front wall of combustion chamber 5, make boiler from adopting single water-coal-slurry to act as a fuel, become simultaneously metabolic water coal slurry and coal gas or the Mobyneb boiler of metabolic water coal slurry or coal gas separately, increased the scope of application of boiler.
Further, gas burner 6 is arranged on the below of coal water slurry fired burner 2.Concrete, when water-coal-slurry and natural gas use simultaneously, light gas burner 6, when the temperature in combustion chamber 5 reaches 800 ℃ of left and right, because hot gas rises, this moment the nozzle (not illustrating) by coal water slurry fired burner 2 to the combustion chamber 5 injection water coal slurries, just can put combusting coal water slurry, thereby can realize 5 internal combustion water-coal-slurry and the natural gases in the combustion chamber; Gas burner 6 can also replace light diesel fuel or the gas ignition device in coal water slurry fired burner 2, thereby has simplified coal water slurry fired burner 2 structures.
