The gas-fired boiler has outstanding eco-friendly advantages, which makes it stand out among various boilers. Due to the high efficiency and fuel characteristics, gas-fired boilers has many protective measures in the operation.

The Protection Systems of Gas-fired Boiler

1. Water level protection system. The normal water level has a great impact on the gas-fired boiler. The water level protection system can avoid accidents caused by boiler water shortage and dry burning. The system also has the alarm function for boiler full water and other problems to warn the boiler operator.

2. Pressure protection system. The pressure protection system can start the interlocked protection if the whole boiler pressure exceeds the rated value. Under the overload situation, the relief valve will be automatically opened to reduce the pressure and closed after the pressure returns to be normal in order to prevent the boiler from explosion.

3. Temperature protection system. The temperature protection is an important procedure in the boiler operation and is also significant for the temperature adjustment and protection of the whole boiler. The common temperature protection device for the furnace is a bi-metal temperature controller.
