Abstract
The invention relates to a grate heat exchange type biomass cooking and heating stove. According to the grate heat exchange type biomass cooking and heating stove, a hollow tube and a stove-body water jacket are communicated with each other at a grate portion and serve as a fixed grate of a stove body, so that the heat energy of the grate portion is utilized sufficiently, and the problems that the grate is subjected to high-temperature ablation, deformation, fracture and early damage are solved; meanwhile, the heat utilization ratio of boilers and stoves is increased, and the service lives of the stoves are prolonged.
Description
Affiliated technical field:
The invention belongs to the thermal energy conversion device of biomass semi-gasification normal-pressure hot-water boiler, specially refer to the device that a kind of biomass cooking stove utilizes fire grate conversion thermal energy.
Background technology:
At present, the normal-pressure hot-water boiler of domestic production generally adopts in body of heater, smoke box water pipe and water jacket is set, and separately sets up vacuum superconductivity tube etc. as the major way of hot water space heating boiler thermal power transfer.But, the excess Temperature at boiler grate position causes fire grate ablation, distortion, fracture and damages too early, and this partial heat energy is not fully utilized, and boiler grate is because of the very easily damage in hot environment that works long hours, not only affect the normal use of boiler, also shortened the service life of boiler.
Summary of the invention:
For the heat energy at existing hot water space heating boiler and Heating stove fire grate position being fully used and solving the problem of fire grate earlier period damage, the technical scheme that fire grate heat exchange type biomass cooking stove of the present invention is taked is: (1). at fire grate position, adopt hollow pipe and furnace water jacket to be interconnected as body of heater fixed grate.(2). position, fixed grate interval is equipped with moving grate again and is used for clearing up the operations such as lime-ash.(3). fire grate heat exchange hollow pipe and body of heater are certain angle of inclination and are connected with the circulation that is beneficial to current.
The beneficial effect that the present invention produces is, first the heat energy at fire grate position is fully utilized, next is that effect due to water circulation in hollow pipe fixed grate makes the high temperature at fire grate position obtain utilization, has solved the problem that fire grate is subject to high temperature ablation, distortion, fracture earlier period damage.Improve the heat utilization efficiency of boiler, stove and accessory simultaneously, and extended the service life of stove and accessory.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is side sectional view of the present invention.
Fig. 2 is that plane fixing, moving grate of the present invention is assembled schematic diagram.
1. fixed grate heat exchanger tubes in figure, 2. moving grate, 3. furnace water jacket, 4. smoke box water jacket, 5 smoke box heat exchange laminates, 6. circulating water outlet, 7. recirculated water entrance, 8. burner hearth, 9. deashing handle.
The specific embodiment:
According to inserting ignited fuel shown in figure in burner hearth (8), after fuel combustion, heated the water in furnace water jacket (3) and smoke box water jacket (4) smoke box heat exchange laminate (5), the heat abstractor that flow of hot water is connected by outside through circulating water outlet (6) passes back into recirculated water entrance (7), and part current flow to furnace water jacket (3) through fixed grate heat exchanger tube (1).In this process, the part heat at fire grate position is recycled water and takes away, and the heat energy at fire grate position is utilized, and the high temperature that fire grate bears makes moderate progress, and fire grate is protected, and boiler thermal output promotes, and has extended service life.When needs are cleared up lime-ash, can shake deashing drives moving grate (2) to clear up lime-ash operation (9).
Claims (3)
1. a fire grate heat exchange type biomass cooking stove, comprise: fixed grate, moving grate, water tank heat exchange laminate, it is characterized in that: fixed grate is hollow pipe, and furnace water jacket is certain inclination angle and is communicated with, moving grate and fixed grate space are also arranged on same position.
2. fire grate heat exchange type biomass cooking stove according to claim 1, is characterized in that: fixed grate is that hollow pipe and furnace water jacket are connected, and moving grate and fixed grate match in cleaning lime-ash.
3. fire grate heat exchange hollow pipe according to claim 1, is only suitable for applying in miniature boiler and biomass furnace.
