Causes and Solutions of Thermal Operation of Gas Generating Furnace

Constitute a gas furnace heat operation of the more common elements are two, the following Shandong Wanfeng gas furnace manufacturers for everyone to introduce.
(1) the saturation temperature is too low, that is, to the bottom of the air duct to participate in the amount of steam less, into the furnace wind water vapor content is lacking, so that the furnace temperature, especially the oxide layer temperature increases, when the temperature exceeds the gray Slag melting point, the ash is melted, forming a block.That not only the furnace along the section of the uniform supply of the wind was damaged, deteriorating the furnace gasification conditions, and because of the existence of large slag, the air flow and carbon contact Surface reduction, carbon dioxide and water vapor failed to react with the carbon through the recovery layer. Effect of gas furnace out of the high temperature, gas C02 more, low calorific value.
In this case, the load of the furnace should be reduced, the full temperature should be advanced, the furnace temperature should be reduced to the specified value, and then the details are treated as follows:
When the slag is not severe, with the probe of the brazing interspersed, broken pieces, and the appropriate amount of coal and the amount of ash, so that the furnace gradually returned to normal.
When the furnace conditions deteriorate, the furnace into a piece of large pieces, in order to ensure the quality of gas and easy to handle, the furnace and the network disconnected, with large steel brazing and hammer to knock slag, to be basically processed Normal and then connected to run.
When the stove can not be made into a single piece of material, had to stop the furnace to play slag, and then processed and then point furnace production.
(2) the production process, when the gas production changes, not timely adjustment of coal and ash amount, constitute the gray layer is too high, the oxide layer shift, gas furnace temperature increased.
When this happens, should be appropriate to speed up the ash and coal, so that the gray layer down to the specified value, the gas furnace can return to normal.
