Abstract
The utility model relates to a civil cooking and warming stove, which is a civil high efficiency cooking and warming stove composed of a hot water system, a steam jet system, a stove door, a stove bridge, a flue, etc. The steam jet system is composed of a steam way, an outer steam pipe, an upper annular jet pipe and a lower annular jet pipe. The hot water system is composed of a stove body water jacket, an overhead water jacket, a flue water jacket and a residual heat collector. A hearth part is additionally provided with a jet pipe. A residual heat gather device is arranged in the flue of the stove, the stack gas temperature of the stove is reduced to 250 DEG from 300 DEG, and the warming efficiency of the stove is enhanced by 3%. The upper part of the stove body is provided with the stove door, the utility model has convenient operation when the utility model is used, and the utility model can keep indoor clean without smoke dust pollution.
Description
The utility model relates to a kind ofly convert coal gas to by coal and burn the domestic cooking warming stove that the thermal efficiency is higher.
Cooking heating furnace is the northern China cold district at the life appliance of people's indispensability in very long winter.In practice for many years, people have created stove and accessory miscellaneous, but still there is a common problem, insufficient heat energy utilization rate of burning is low, the radiator quantity few (about the 8--10 sheet) that drives, people improve in living standard, and under the living space condition of enlarged, originally the stove and accessory of form just can not have been satisfied the demand.
Have in the patent documentation by coal in recent years to convert the stove and accessory that coal gas burns to, as the Sun Shi paramos hot water space heating boiler of number of patent application 91227861.But because of its air jet pipe is located at below the grate, when dust stratification increases on the grate, the chance that the steam of ejection and scorching hot coal connect reduces, gasification result and combustibility variation, this stove and accessory has only the flue water jacket to absorb the flue gas heat exhaust gas temperature simultaneously, and heat energy utilization is still poor, and heating the time must be removed cooker, at the furnace roof coal, operation is inconvenient and can room air be polluted to excessive cigarette.
The purpose of this utility model provides a kind of domestic cooking stove and accessory, overcomes the shortcoming of prior art, improves burning of coal efficient and heat energy utilization rate.
The utility model is to realize like this, the vapour injection part is except that grate has jet pipe, grate top also is provided with jet pipe, so just be not subjected to influencing of grate dust stratification, on the corresponding combustion chamber in last jet pipe hole, be provided with air channel when spray orifice sprays, the negative pressure of generation on every side, down along groove introduce burner hearth in combustion-supporting from grate air, the vapor volume that enters of jet pipe can be used valve regulated up and down, make the stove internal combustion arrive optimum state, also increased by 1 group of pipe heat exchanger except that the flue water jacket is arranged aspect absorbing flue gas heat energy, exhaust gas temperature can descend about 50 ℃ like this, furnace thermal efficiency can improve 3%, upper of furnace body is provided with fire door, and the coal of cooking needn't mobile cooker, and cigarette can not overflow during coal yet.
The utility model is described in further detail below in conjunction with accompanying drawing;
Fig. 1 is a longitudinal sectional view of the present utility model
Fig. 2 is that the A-A of Fig. 1 cuts open sleeve figure
Fig. 3 is the B-B cutaway view of Fig. 2
Fig. 4 is the C-C cutaway view of Fig. 2
Fig. 5 is the D-D cutaway view of Fig. 2
Among the figure: 1, furnace water jacket 2, fire door 3, overhead water jacket 4, bell 5, flue water jacket 6, pipe heat exchanger 7, beat ash mouthfuls 8, hot-water line 9, combustion chamber 10, go up toroidal nozzle 11, grate 12, grate prop up iron 13, down toroidal nozzle 14, water tank 15, return pipe 16, valve 17, outer steam pipe 18, steam water jacket 19, interior steam way 20, coal filling hole 21, go up spray orifice 22, articulation 23, ventilation groove 24, spray orifice 25, ash hole down
Stove is the double-layer plate welding, interlayer just forms furnace water jacket [ 1 ] in the middle of it, flue water jacket [ 5 ], they and overhead water jacket [ 3 ], pipe heat exchanger [ 6 ] all+be communicated with, the hot water of each water jacket is delivered to the radiator heat radiation by hot-water line [ 8 ], after return pipe [ 15 ] returns the furnace water jacket bottom, in burner hearth, be close to furnace water jacket one side, steam generator is arranged, middle separating with plate forms two parts, left-hand component is interior steam way [ 19 ], right-hand component is steam water jacket [ 18 ], and [ 18 ] and [ 19 ] bottom is obstructed, and top communicates, so steam of steam water jacket generation, wherein a part enters interior steam way [ 19 ] by top, and the bottom of [ 19 ] and last toroidal nozzle [ 10 ] communicate, and steam is sprayed by last spray orifice [ 21 ].Steam another part in the steam water jacket then enters down jet pipe [ 13 ] by spray orifice [ 24 ] ejection down by outer steam pipe [ 17 ].Valve [ 16 ] but adjustable pipe road resistance enters the ratio of the vapor volume of toroidal nozzle up and down thereby regulate, can make the generation of stove internal combustion and water-gas be in optimum state.
Ward off in the burner hearth with fire clay, form combustion chamber [ 9 ], and with on spray [ 21 ] corresponding position make 10 * 10 air channels [ 23 ], when last spray orifice uperize, negative pressure of generations makes air combustion-supporting through air channel introducing burner hearth below grate around it.
Upper of furnace body has fire door [ 2 ], lid can be opened during coal, and ash hole [ 25 ] is arranged at the bottom, and the bell at body of heater top [ 4 ] can take off when cooking, and it can be covered when heating up water heating.
The bottom of little water tank [ 14 ] and steam water jacket [ 18 ] is communicated with, little cistern water level, be the water level of water in the steam water jacket so the top that little tank top must be lower than the steam water jacket, the space that water vapour is held in the top retention of steam water cover be could guarantee like this, steam channel and the unlikely water inlet of jet pipe guaranteed.
Pipe heat exchanger [ 6 ] is in order to increase the collection of waste heat, when in its smoke pipe during dust, can open ash mouthful [ 7 ] and clear up.
