Impact of Fuel Quality Low-quality fuel typically contains high levels of ash, sulfur, and other impurities. These impurities produce significant amounts of smoke and harmful gases during combustion, leading to severe clogging and wear in the air preheater. For instance, when the sulfur content in the fuel is high, sulfur dioxide generated during combustion combines […]

The Importance of energy-saving retrofits for gas boilers Gas boilers generate thermal energy but also result in energy loss. Unreasonable design and operational methods can lead to low energy efficiency, increasing both energy consumption and environmental pollution. Consequently, implementing energy-saving retrofits is essential. These retrofits not only reduce energy consumption and operating costs but also

Sonic ash cleaning refers to the use of the energy of the sound field to remove ash from the surface of the boiler heat exchanger. It generates sound energy by oscillating pressure within a cavity, emitting high-intensity sound waves. This causes air molecules and dust particles in the affected areas to resonate, preventing and disrupting
