Skills for reducing noise and saving energy during boiler operation
Although the industry is developing, environmental pollution is becoming increasingly serious. As one of the environmental pollution, noise pollution has become one of the major hazards to human health. This type of pollution will also be generated during the operation of boiler equipment, and targeted measures should be taken to overcome it.
For traditional coal-fired boilers, in order to make the boiler burn, a blower will be added during use, but this device has also become the main source of noise pollution. Now that we know the reason why the boiler generates noise during operation, to eliminate and reduce the noise of the boiler, we need to combine the fan noise reduction and energy saving in the process.
On the one hand, the process layout of the boiler room can be appropriately adjusted, such as placing the blower, induced draft fan and other equipment in the soundproof room respectively, and connecting them to the main machine with ventilation pipes; then open an air inlet on the top or wall of the soundproof room, and install a muffler for air intake in the machine room.
On the other hand, from the perspective of plane layout, the blower can be close to one side of the boiler room, the air inlet is set on the upwind side, and the motor is placed in the middle of the air flow channel. In this way, when the boiler is running, the blower generates negative pressure in the soundproof room, so that a large amount of outdoor fresh air automatically enters the soundproof room.
After the air enters, it first exchanges heat with the induced draft fan motor to cool it down, so that the indoor temperature is maintained. Since the noise reduction capacity of the soundproof room and the air inlet silencer is relatively large, the noise reduction of the boiler is easy to achieve.
On the other hand, using the boiler blower to send the preheated air into the boiler for combustion to achieve energy recycling, it also has economic benefits and has a good effect on energy saving of the boiler.
