The main features of gas furnace equipment

1. Good energy-saving effect: The lining of the furnace body of this equipment is all made of high-aluminum refractory fiber. Compared with refractory bricks, it has a lower thermal conductivity and heat capacity, so the thickness of the refractory layer is small and the heat absorption is greatly reduced.
This equipment adopts a high-speed temperature-adjusting burner system with a high ejection speed of 100m/s, which can effectively stir the furnace gas, make the furnace temperature uniform, and the burner system burns completely, so that the fuel is fully utilized. The furnace pressure zero-position control and full sealing technology are adopted, so that the maximum bonding surface (the sealing surface between the furnace car and the furnace body) is at zero furnace pressure, the furnace gas does not leak out, and the cold air does not infiltrate, so that the heat energy generated by combustion can be effectively utilized.
2. High degree of automation: The furnace door and furnace car are all electric, with an operating console, and the operator can easily control the operation of the furnace door and furnace car. The furnace door and furnace car have travel control, and can automatically stop running at the limited limit position to ensure safety.
? The combustion system has a full set of ignition, high and low fire operation, detection, flameout alarm, flameout cut-off and re-ignition functions, and each burner has an independent control box, which can be controlled separately. Each control box interface can be connected to the instrument room temperature controller, so that the whole system can be automatically controlled.
The pipeline parameters are automatically controlled. The pipeline pressure of the combustion air and fuel can be set and automatically adjusted to control the amount of combustion air and fuel at the optimal ratio, ensuring a higher combustion efficiency and eliminating black smoke.
The furnace pressure is automatically controlled. The furnace pressure signal is compared with the set value through the pressure transmitter, and the signal is transmitted to the chimney actuator. The pressure in the furnace is automatically controlled by changing the chimney opening.
The temperature control in the furnace adopts an advanced intelligent digital display temperature controller, which forms a closed-loop control with the temperature measuring element and the automatic control burner. It has high precision, high flexibility, anti-interference and high reliability. The temperature control system can automatically calculate, operate, display and store the heat treatment production process curve to achieve full process control.
The instrument cabinet is equipped with operating value display of temperature, furnace pressure, various burners, and various pipeline parameters, as well as abnormal situation alarm and emergency protection measures to ensure safe operation.
Hot standby order and production conversion order
1. Any furnace with water jacket leakage, stirring rod leakage, or stirring water seal leakage should not be converted to hot standby furnace. Any furnace with serious air branch valve not closed tightly or serious saturated steam valve leakage that cannot be repaired and replaced during hot standby should not be used as hot standby.
2. For planned hot standby, a furnace with better furnace condition should be selected for hot standby. If the fire layer is lowered and the furnace is seriously slagging, the furnace condition will inevitably be worsened.
3. For the planned hot standby furnace, the furnace should be explored in advance, and the part with a small amount of slagging should be broken by large chisel, and the chisel should be poked at each point of the furnace section to make the points of the furnace section basically consistent in tightness.
4. Appropriately reduce the ash slag layer.
5. Appropriately thicken the coal layer.
6. Check whether the bell cover of the maximum relief valve is flexible.
7. Reduce the air volume before hot standby.
8. Seal the double vertical pipe water seal and pull up the maximum relief valve in time according to the furnace outlet pressure.
9. Close the branch pipe air valve and saturated steam valve.
