Gas-fired hot water boilers require high-quality water to improve the boiler performance and extend the service life. If the boiler uses the tap water of water which contains a lot of impurities, magnesium and calcium ions in the water will form white precipitates when the water is heated at high temperatures, which can cause the scaling problem to reduce the heat transfer efficiency of the boiler and bring hidden dangers of the boiler safety.
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, the gas-fired boiler has many protective measures in the operation.
It is inevitable for gas-fired boilers to produce noise including heat exchange noise, aerodynamic noise, mechanical running noise and other noise after ignition.
Facing the aggravation of environmental pollution, many industries have been required to meet the pollutant emission standards. As a kind of thermal energy equipment, the boiler has high pollutant emission. However, the implementation of environmental protection policies has prompted enterprises to use energy-saving and eco-friendly boilers. Therefore, let us talk about the characteristics of the gas-fired condensing boiler here.
There are many applications of hot water boilers. With the environmental protection requirements become stricter, the hot water boilers are mostly gas-fired. Therefore, it is important to know how to use the gas-fired hot water boilers safely and what are the maintenance methods.
Whether the water quality in the gas-fired boiler reaches the required standards is directly related to the safety, performance and service life of boiler. The water must be treated before the boiler operation. However, what are the water quality standards for the gas-fired boiler?
In the boiler operation,the flue gas discharged from the flue gas duct has a certain temperature. However, the abnormal increase of flue gas temperature in boiler's flue gas duct is usually accompanied with other abnormal phenomena. In this regard, corresponding measures should be taken for adjustment based on the reason analysis.
1) Set up the air preheater. One of the most effective measures to improve the thermal efficiency of thermal oil heater is to use an air preheater for heat recovery. 2) Use waste heat boiler for heat recovery. The waste heat boiler uses the waste heat in the flue gas exhausted from the thermal oil heater to heat water or generate steam.
