Abstract
The utility model discloses a coal-fired and gas-fired dual-purpose vertical hot-blast stove which comprises a combustion chamber. A smoke guiding machine is connected with the combustion chamber, a heat exchanger is connected with an air blower and provided with a hot air outlet, grate bars are arranged at the bottom of the combustion chamber, an ash removal chamber is arranged below the grate bars and connected with an air inlet, the combustion chamber is connected with a gas delivery combusting device, the gas delivery combusting device comprises a gas inlet pipeline connected with the combustion chamber, and the gas inlet pipeline is also connected with a gas device. The gas delivery combusting device is added on the basis of an original coal-fired vertical hot-blast stove, so that both coal and gas can be used for the hot-blast stove, and the shortcoming that heating equipment needs to be purchased due to unstable gas is avoided.
Description
Technical field
The utility model relates to a kind of fire coal, the dual-purpose vertical hot furnace of combustion gas.
Background technology
Vertical hot furnace generally uses as north China mine winter heating equipment, adopts vertical all steel Welding Structure more, is made up of combustion chamber and heat exchanger, and combustion chamber and heat exchanger are integrated.
Can be divided into coal-fired hot-blast stove, fuel gas hot-blast stove and warm air oil furnace by burning with fuel on the market, but each fuel type of furnace is single, incompatible.
Advocate energetically in country under the proposal of " energy-saving and emission-reduction, comprehensive utilization ", highly gassy mine with good conditionsi is collected the fuel of back as winter heating with fire damp gas.
But the fire damp source of the gas is unstable, does not have methane gas in possible a period of time, so the hot-blast stove of single-fuel can not satisfy the demand of real bargh on the market.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of fire coal, the dual-purpose vertical hot furnace of combustion gas are provided; It increases methane gas and carries burner on the basis of original coal-fired vertical hot furnace; Reach the hot-blast stove fire coal, combustion gas is compatible, avoided this unstable gas of invar simultaneously and repeated to purchase the drawback of heating equipment.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of fire coal, the dual-purpose vertical hot furnace of combustion gas, comprises the combustion chamber, and the bounded of said combustion chamber is wound with a circle heat exchanger, and said combustion chamber and heat exchanger are the structure that is integrated.Said combustion chamber is connected with smoke suction machine, and said heat exchanger connects an air blast, and heat exchanger is provided with hot wind outlet; Bottom, said combustion chamber is provided with fire bars; Said fire bars below is a dedusting chamber, and said dedusting chamber connects air inlet, and said combustion chamber connects a methane gas and carries burner; Said methane gas carries burner to comprise the methane gas air inlet pipeline that is connected with the combustion chamber, and said methane gas air inlet pipeline connects the methane gas device.
Said hot-blast stove is provided with electric control gear, is provided with temperature sensor in the combustion chamber, and the methane gas air inlet pipeline is provided with pressure sensor, and temperature sensor is connected with electric control gear respectively with pressure sensor.
The methane gas air inlet pipeline is provided with the methane gas intake valve.
The utility model increases methane gas and carries burner on the basis of original coal-fired vertical hot furnace, reach the hot-blast stove fire coal, combustion gas is compatible, has avoided this unstable gas of invar simultaneously and repeats to purchase the drawback of heating equipment.
The structure that the utility model adopts combustion chamber and heat exchanger to be integrated; On the basis of original coal-fired vertical hot furnace, increase methane gas and carry burner; Utilize coal-fired high temperature that methane gas is lighted; Because of flue gas is extracted out by smoke suction machine, thus be negative pressure in the whole combustion chamber, the flue gas after the gas combustion or have unburned methane gas all can be taken away by smoke suction machine; In the combustion chamber, establish simultaneously a temperature sensor; On the methane gas air inlet pipeline, establish a pressure sensor; When the temperature sensor measurement chamber temperature is lower than the gas ignition temperature or admission pressure is lower than setting value; Electric control gear all can alarm stoker personnel be checked, operated, and guarantees the methane gas safe combustion, ensures the hot-blast stove safe operation.
The utility model is coal-fired, the dual-purpose vertical hot furnace of combustion gas; Solved the methane gas safe combustion problem under the gas source of the gas instability condition; Make the unsettled gas source of the gas of highly gassy mine obtain effective utilization; Two kinds of fuel easy switchings have outstanding social benefit, economic benefit and environmental benefit simultaneously.
