There Are Several Kinds Of Burning Rule Of Hot Air Stove. Characteristics Of All



Now, the selection of the hot air stove can be divided into three kinds of burning criteria:
(1) the fixed amount of gas, the amount of combustion air conditioning;
(2) a fixed amount of combustion air conditioning, gas volume;
(3) the amount and the amount of combustion air conditioning gas.
Their respective characteristics are described as follows:
(1) the fixed amount of gas, the amount of combustion air conditioning. This approach is in hot blast stove all burned in the period, always cover type bright annealing furnace to gas quantity is unchanged, the appropriate conditioning the amount of combustion air for burning aluminum alloy car type hot blast stove burning. Because all burning period has been with the largest amount of gas, when after the arrival of the top temperature rules, by adding the amount of combustion air, adhere to the temperature of the, and then add the hot blast stove burning intensity. Because the gas volume is added, the flow velocity is increased, which is good for the heat transfer and the heat exchange effect of the hot air stove and the lower part. Therefore, this is a good way to strengthen the open burning furnace. However, this method only applies to the amount of combustion air blower can be left to the stove with harmonic.
(2) a fixed amount of combustion air conditioning, gas volume. This approach is kept unchanged in the amount of combustion air conditioning all incineration period, appropriate gas amount for incineration. Such burning way in insulation reduction in the amount of gas, also is to cut the amount of flue gas, reduce the strength of the hot blast stove of burning, the hot air furnace heat transfer unlucky. However, the adjustment is convenient, easy to grasp. Applicable to combustion fan to lack and the amount of combustion air conditioning stove can.
(3) the amount and the amount of combustion air conditioning gas can. This approach is in pre incineration using the maximum amount of gas and appropriate combustion air volume cooperation incineration, when after the arrival of the top temperature rules, together with the reduction gas and combustion air volume to adhere to the top temperature. This way the biggest drawback is difficult to grasp the gas and air cooperation than, to adhere to the top temperature constant. While the gas and air cut, it will cause the burning intensity of the hot air stove to reduce, so that the whole heat of the hot air stove. Therefore, this approach in addition to the gas pressure to shake the big hot air stove and used to control the heating temperature, usually very little choice.
