Abstract
The utility model discloses a multi-functional fixed fire grate boiler device, which comprises a hearth with a front wall, wherein the middle part of the hearth is provided with a flame dyke; and the front wall is provided with a burning port. The multi-functional fixed fire grate boiler device is simple in structure, can be used for realizing multiple purposes of a boiler, can be used for burning coal, rice hull, wood chips and the like, burns completely, and has low exhaust smoke level.
Description
Technical field
The utility model relates to the boiler technology field, is specifically related to a kind of multipurpose fixed grate boiler device.
Background technology
At present, along with Chinese economic development, the application of boiler in life, production more and more widely; Because of boiler is a highly energy-consuming equipment, be accompanied by the rising steadily of price of coal, some enterprises are in order to reduce production costs; Directly utilize cheap biomass fuel (like rice husk, wood chip etc.).Not only responded the policy of national energy-saving, emission-reducing, environment friendly with biomass as fuel, and carried out " refuse " and utilized.
The biomass fuel that Industrial Boiler used, in the majority with wood (bamboo) bits, rice husk, firewood, stalk etc., using this class A fuel A has tangible economy and environmental benefit.These fuel catch fire easily, and are cheap, and burning back sulfur oxide, nitrogen oxide discharge capacity are low, can reduce boiler applying unit production cost and reduce the pressure that the environmental protection aspect is brought.But most of users do not consider difference, the especially difference of combustion characteristics aspect coal-fired and burning-used biologic mass fuel well, often coal-burning boiler are directly changed the burning biomass fuel, thereby have brought the problem of a series of safety and economic operations aspect.
Summary of the invention
The technical problem that the utility model solved is to provide a kind of multipurpose fixed grate boiler device, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of multipurpose fixed grate boiler device comprises the burner hearth with front wall, it is characterized in that; The middle part of said burner hearth is provided with firebreak; Increase on the one hand the disturbance of burner hearth flue gas, postpone heat-exchange time, make the ash after containing some unburneds in the flue gas rice husk burning with rice husk completely on the other hand; Form a gravitational settling district herein, reduce the content of ash particle in the flue gas.The utility model is reasonably organized burning, and chamber structure is transformed, and owing to the volatile matter of rice husk, wood chip etc. is higher, the characteristics that ignition temperature is low under the prerequisite of existence conditions, increase combustion space, and prolong smoke is in the time of staying of burner hearth.
As a kind of improvement, said front wall is provided with spray combustion mouth.Can be convenient to the utilization of boiler better, can be coal-fired, can burn rice husk, wood chip again, do not change boiler structure again, be convenient to intercommunication.
Owing to adopted above structure, the utlity model has following beneficial effect:
The utility model is simple in structure, can realize the multipurpose of boiler, both can be coal-fired, again can combusting rice hull, wood chip etc., and sufficient combustion, exhaust smoke level is low.
Boiler uses its expense of biomass fuel and time ratio fire coal to save.0.5 ton of boiler burning-used biologic mass fuel will reduce by 25% than burning coal, and the time can save 30%, and coal is very big to the boiler corrosion effect, and no graininess carbon and corrosive gas such as sulfur dioxide, carbon monoxide in this fuel flue gas are very little to the effect of boiler corrosion property.So burning-used biologic mass fuel is much more superior than using coal aspect boiler.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of multipurpose fixed grate boiler device comprises the burner hearth 1 with front wall 2; It is characterized in that the middle part of said burner hearth 1 is provided with firebreak 3, increase the disturbance of burner hearth 1 flue gas on the one hand; Postpone heat-exchange time; Make the ash that contains in the flue gas after rice husk and the rice husk burning completely of some unburneds on the other hand, form a gravitational settling district herein, reduce the content of ash particle in the flue gas; In addition, present embodiment is reasonably organized burning, and burner hearth 1 structure is transformed, and owing to the volatile matter of rice husk, wood chip etc. is higher, the characteristics that ignition temperature is low under the prerequisite of existence conditions, increase burner hearth 1 volume, and prolong smoke is in the time of staying of burner hearth 1.
In the present embodiment, said front wall 2 is provided with spray combustion mouth 4.Can be convenient to the utilization of boiler better, can be coal-fired, can burn rice husk, wood chip again, do not change boiler structure again, be convenient to intercommunication.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
.
