Description

Coal, the dual-purpose stove of igniting of gas

Technical field

The utility model belongs to cooking stove, particularly, belongs to the cooking stove that is applicable to two or more fuel.

Background technology

Cooking stove is the indispensable apparatus of family life.Cooking stove be unable to do without fuel.Present common coal fire stove is generally ignited with timber, in the process of igniting, will produce a large amount of dense smoke and dust, this will cause serious destruction to ecological environment, and will be to the house. household electrical appliance and furniture cause great infringement, and the people lives in for a long time in the environment of dense smoke and dust and also is attacked by a disease easily; Use also extremely inconvenient simultaneously.Though along with expanding economy, common coal fire stove will be replaced by electric furnace and gasification furnace, latter's expense height, part family is difficult to bear.Adopt the patent application of the cooking stove of two kinds of fuel to have tens of kinds in recent years, for example No. 90204641.1 " using gas-coal co-using stove ", No. 91231352.8 " bottle coal double-purpose oven ", 91227235.X number " bottle coal combination stove ", No. 99233521.3 " gas, coal multipurpose furnace ", No. 01258348.0 " energy-conservation combination coal, gas furnace " etc. more, these patents all belong to new design, but people are also designing novel cooking stove, the various shortcoming when igniting to change house coal stove kitchen range.

Summary of the invention

The purpose of this utility model provides a kind of coal, the dual-purpose stove of igniting of gas, changing defective and the deficiency of common coal fire stove in the process of igniting, and serves many purposes.

The coal that the utility model provides, the dual-purpose stove of igniting of gas, shaft, stove seat, combustion chamber, furnace panel, grate, ash bin and smoke evacuation tube with common air return stove, its feature is having a space and passage respectively below the grate with above the combustion chamber, connecting by nut with slide block is that holistic gas spray head is inserted the space of below or top by passage, and is placed on space center; Gas spray head is responsible for coal gas by gas pipeline or LPG cyoinders links to each other, and burnt gas valve is arranged on the gas pipeline.

Coal, gas be dual-purpose ignites the stove lower channel in a side of stove seat, and backplate is arranged at lower channel top, and gripper shoe and locating piece are arranged at the bottom, in order to the position of determining that gas spray head is placed; Upper channel is in a side of shaft, and there is gripper shoe its underpart, and the upper channel mouth has the protective plate of a band handle, is used for closing passage, prevents leaking of burnt gas.

Grate adopts rotary grate usually, on the stove seat supporting pin is installed; Each one of loose pin and fixed locating stud also is installed.Under the situation of not using coal combustion, grate rotates to the position of supporting pin, like this, directly with the combustion gas heating, just is unlikely to burn out grate.

The distance of the upper surface of backplate and gas spray head is enough little, stops up gas spray head so that prevent cinder; The below that ash bin is positioned at gas spray head is the cinder that is used to adorn after the burning.

The coal that the utility model provides, the dual-purpose stove of igniting of gas have 3 kinds of usages: prevailing usage is ignite a coal in the combustion chamber of the high temperature that utilizes the fuel gas buring of gas spray head ejection to produce, and fire coal can be used lump coal, also can use moulded coal; Do not having under the situation of coal, directly combustion gas is when gasification furnace use heat supply; Also gas spray head can be placed on the superjacent air space of stove, when gas range uses.

Adopt first kind of usage, because the burning heating anthracites of using more, and being a kind of high catching fire, anthracite lights material, ignition temperature is 360～420 ℃, the flame temperature that produces during fuel gas buring is 550～680 ℃, be higher than the anthracite ignition point, so energy ignition furnace coal in the heart, the time of igniting is greatly about 4～6 minutes; Behind the coal in the combustion chamber that ignites, gas spray head be withdrawed from down side space, otherwise the cinder of discharging will fall on gas spray head, cause shower nozzle to stop up.

The coal that the utility model provides, the dual-purpose stove of igniting of gas have energy-saving and environmental protection, cleaning, health, safe, cheap advantage, are a kind of ideal simple in structure, easy to use heating stoves.
