Pre-operational Inspection of Gas-fired Thermal Fan
To ensure that the pre-inspection of the gas-fired thermal fan is carried out, to check whether the equipment in front of the furnace meets the acceptance standards, and to familiarize oneself with the operation of all the work so as to ensure the quality of the pre-inspection. The slag channel, iron hook, and supporting iron hook are set up and dried with fire. At the beginning, the amount of iron in the furnace is small and the fluidity is poor, so preparation is needed for the little pit. If necessary, a temporary pit is set up.
Inspection of the electrical part of the gas-fired thermal fan to see if it is feasible, whether the furnace cover is grounded well, whether the heating element is short-circuited or opened. Improper treatment of the main iron channel. To prevent the iron in the furnace from being of poor activity, the storage type of iron is changed to over-iron type. If the supporting part of the blower at the top of the furnace has already changed to the circulating cooling^ water cooling^ structure, please check whether the circulating water loop is normal.
Improvement of the configuration of the gas-fired thermal fan, adding induction coil, copper tube of reactor, etc., reducing loss, saving 30-80 degrees of electricity. Increasing the speed of the gas-fired thermal fan can reduce loss, because in the heating process, part of the heat is lost to the air, and the other part is cooled by cooling water. The faster the speed, the shorter the heating time, and the shorter the cooling time. Therefore, acceleration is an important condition for energy saving.
Carefully observe the flame and furnace temperature of the oxygen, oxygen bag, oxygen pipe, and breaking rod, and prevent deformation due to high temperature; during operation, manually adjust the air supply quantity according to the temperature of the dryer and the heating furnace to stabilize the air temperature of the dryer; check the operation of the blower and gas supply, and avoid abnormal phenomena.
The amount of cement and mortar in the electric furnace should not be too much, and the iron should be filled to the top. Before the furnace is opened for gas supply, the gas channel is placed in the mortar jacket and the water valve mud shield is judged to be ready, remove the pipeline, and then wipe the water valve mud cover. Determine whether the sealing material of the gas-fired thermal fan cover is intact and damage-free. Prepare auxiliary materials such as blasting mud, channel materials, and insulation materials.
When the energy consumption of the gas-fired thermal fan is large, power measurement is also an auxiliary guide for production operation. Therefore, the production of the gas-fired thermal fan should strictly implement the equipment maintenance plan to reduce downtime and maintenance costs, and improve production efficiency. In the use of the gas-fired thermal fan, the "intermediate production" method can be used, dividing the energy use into several stages, putting the high-energy consumption stage in the low-power consumption stage.
Methods for handling cold temperature in gas-fired thermal fan: Before operation of the gas-fired thermal fan, reduce the air volume by about 50% to control the material speed and prevent the furnace temperature from dropping further. When the air volume decreases, add a batch of clean charcoal, and the loading of the carbon burden is correspondingly reduced. Make every effort to exhaust the slag before slagging, try to avoid the pressure blast at the furnace mouth and the damage caused by the slagging, and wait for the clean charcoal to arrive at the furnace mouth. Ensure the symmetry of the air pressure and air volume to avoid material collapse and suspension.
