Existing stove, the normal employing separately of kitchen range are used, and at collectiveity canteen, catering industry is still with bulk coal-fired eyes range of returning-air, shape of a hoof bellows kitchen range is main, the part catering industry, and family also uses the coal-saving range that dryouies honeycomb briquette, but all be to have adopted fixed combination or whole moving, constitute a fire one usefulness.Japanese according to the retrieval the Seventh Five-Year Plan---special permission, the new case in 8 or four years are collected newspapers, and civilian cooking stove is all with liquefied gas cooker, and steam stove, electric furnace aspect develop.

The utility model be by improved to burn the multipurpose coal-saving range of wet honeycomb briquette, it has a transportable special body of heater, fixedly kitchen range frame and fire door coal feeder are formed, and are provided with a kind of residual heat using device of being made up of return duct water heater, fire-regulating plate, hot-tub, chimney on the kitchen range mouth of fixing kitchen range frame.

Task of the present utility model is finished as follows.Body of heater 5(Fig. 1) moves on track 1 by go-cart 2.Can be according to steamed rice, cooking, family's heating waits to be needed, and mobile body of heater 5 achieves the goal.Pot 7 is supported on the range panel 3 on water heater 4 tops, and the water heater 4 return duct effect of having held concurrently is by fire-regulating plate 6 adjusting the bottom of a pan firepower.Hot flue gas enters iron sheet chimney 9 through flue 14, and iron sheet chimney 9 is to pass in the hot-tub water, and after the waste heat absorption with flue gas, low-temperature flue gas rising edge earthen-ware pipe (or brick) chimney 11 is discharged outside the rooms, and exit gas temperature is lower than 70 °.Water heater 4(Fig. 2), be welded into galvanized iron sheet 13, hot water ball valve 12, smokejack 14, convection tube 8 are communicated with hot-tub, following pipe advances cold water, last pipe goes out hot water, is provided with gate valve at last pipe, according to cooking operation firepower needs, at any time block the circulation of water in the water heater 4, unaffected to guarantee the bottom of a pan high temperature.

Body of heater 5(Fig. 3) being combined into a special coal-saving stove by 1 millimeters thick iron sheet outer casing 16, cast iron burner 17, cast iron grate 18, flue 19 is placed on the small handcart of band steamboat.Coal feeder (Fig. 5), it is combined into by handle 22, shell 21, plug 23, connecting rod 24, connecting rod 24 is welded into four groups with plug 23, every group can be taken out separately, when the humidification honeycomb briquette, coal feeder is placed on the cast iron burner 17, add with the coal cutter coal slime that will wet that tamping polishes in the coal feeder, take off four core assembly rods respectively, take off the coal feeder shell.From the slag notch Panasonic cinder of body of heater 5, till the wet honeycomb briquette open hearth mouth that newly adds.

Technical parameter of the present utility model:

1, flue optimum formula:

Adopt fire clay 35%, white cream mud 35%, fire sand 20%, iron sand head 9.5%, acetin 0.5% water mixing is mixed well and is smash ripe back use punching block compression moulding, airing.

2, body of heater can be banked up a fire 48 hours continuously.

3, evenly heat efficient is more than 50%.

4, get angry 1.5 °/minute of speed.

5, day coal saving rate＞25%.

6, a lump coal can be worked continuously two hours.
