Abstract
A gas stove with a molded line hearth is provided. A housing part is added between a barrel-shape space hearth and a spherical pot surface in a conventional big pot gas stove, and the housing part called the molded line hearth is made of a refractory material and is similar to the spherical pot surface; a narrow channel is formed by the spherical pot surface and the inner side surface of the molded line hearth, and thus the heat transfer is enhanced, the ability of the pot surface to accept heat is increased, and the thermal efficiency of the gas stove is greatly improved.
Description
Affiliated technical field: the present invention relates to a kind of kitchen range, specially refer to a kind of refractory material molded line burner hearth technology of utilizing to promote the gas kitchen ranges of the thermal efficiency
Background technology: now use the shortcoming of cauldron gas-cooker (Fig. 2) to be: 1. exhaust opening (13) just is arranged in burner hearth below, and the high-temperature fuel gas of also not working is just by bypass, and the heat energy of combustion gas is not fully used; 2. because combustion gas flow velocity in large space (10) is little, convection heat transfer intensity is low between the spherical heating surface of pot and combustion gas, so that pot is accepted the ability of combustion gas heat.These two shortcomings are so that the thermal efficiency of traditional cauldron gas-cooker is very low.
Summary of the invention: the purpose of researching and developing this refractory material molded line burner hearth is to improve the thermal efficiency of gas-cooker.Check Fig. 1, similar to a spherical pot face shape housing (3) made from refractory material, it is tightly by a spherical pot face (2) jail that is fixed, this housing just is called the molded line burner hearth, its underpart is molded line burner hearth fuel gas inlet (4), flow through next high-temperature fuel gas from molded line burner hearth fuel gas inlet, make progress into the flow through narrowed flow path (5) of spherical pot face and molded line burner hearth medial surface composition of radiation-like, combustion gas is flowed in narrowed flow path and improved significantly heating strength than flowing because flow velocity increases in barrel-shaped space, through the high-temperature fuel gas after the strong heat exchange, heat is passed to heated food by pot face (2), the temperature decrease, then a circle slit outlet flue (6) that is formed by molded line upper furnace and bottom, pot edge (1) flows out, and is collected by smoke-collecting apparatus (7) and enters at last flue (8).Description of drawings: below in conjunction with accompanying drawing to the present invention " a kind of spherical molded line burner hearth gas-cooker made from refractory material " be described in further detail.
Fig. 1 is the molded line burner hearth schematic diagram that the refractory material of gas-cooker of the present invention is made.
Fig. 2 is the barrel-shaped space burner hearth schematic diagram of traditional cauldron gas-cooker.
1 is the bottom, pot edge among the figure; The 2 pot spheres for kitchen range of the present invention; 3 is refractory material molded line burner hearth; 4 are type candied fruit burner hearth fuel gas inlet; 5 is narrowed flow path; 6 is the slit outlet flue; 7 is smoke-collecting apparatus; 8 is flue; The pot sphere of 9 traditional large stoves; 10 is the barrel-shaped space of burner hearth; 11 is the burner hearth fuel gas inlet; 12 is a refractory material burner hearth ancient piece of jade, round, flat and with a hole in its centre; 13 is smokejack.
The specific embodiment: select traditional cauldron gas-cooker of a glance Φ 800, the refractory material barrel-shaped space burner hearth of this kitchen range is changed into the spherical molded line burner hearth of refractory material, to the fixed structure of what molded line burner hearth, those skilled in the art can both design, and need not to give unnecessary details.The below is exactly the thermal performance test of these two kinds of kitchen ranges, result on probation.
" barrel-shaped space burner hearth kitchen range " " molded line burner hearth kitchen range "
1 spinner flowmeter, 77 lattice 76
33 kilogram 33 of 2 healed water weight
10 ℃ 23 of 3 water initial temperature
90 ℃ 94 of 5 water end temperature
5 calculate efficient heat 2640 kilocalories 2343
6 get oil gas low heat value 10000 kilocalories/kilogram 10000
7. consume 0.8835 kilogram 0.3664 of oil gas weight

Annotate:
※ 1 is contained in the thermocouple thermometer on the pot cover, when surveying water temperature, checks with glass-stem thermometer.
※ 2 spinner flowmeters are indicated the size of firepower through demarcating by it, it is generally acknowledged, must compare the thermal efficiency of two kitchen ranges under identical firepower condition.
※ 3 thinks that the pot cover heat radiation brings heat roughly to disappear mutually with air.
※ 4 heat power of gas burner are larger, and namely the oil gas weight flow is larger, and the thermal efficiency is just lower, " barrel-shaped space burner hearth kitchen range " when testing, the oil gas weight flow only has G
F=2.379Kg/H, the measured thermal efficiency is larger compared with this kitchen range maximum fire 4Kg/H operating mode because its useful heat flow is too low, only have 7110.1 kilocalories/time, therefore this kitchen range has to often be operated in high flame 4Kg/H operating mode, though the thermal efficiency is smaller.
※ 5 exhaust temperature t
GasMeasuring point is in the furnace exhaust mouth outside.
Through long term test, on probation, the excellent Zhuo of thermal performance data and stable has shown validity and the practicality of refractory material molded line burner hearth gas-cooker.
