During the ignition and operation of the chamber combustion boiler fueled by pulverized coal, oil or combustible gas, improper operation can cause the deflagration or secondary combustion in the furnace or flue gas duct, which can further cause the increased pressure in the furnace. When the pressure reaches a certain value, the explosion-proof door is necessary to open automatically to protect the furnace wall of the boiler.
A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
With the upgrading of energy-saving technology of industrial boilers, condensing boilers with higher thermal efficiency are widely used. Some users will find that there is water flowing out of the tail of the boiler flue during use, they may consider the situation as the boiler is leaking, but it is actually condensed water in the boiler. This paper introduces how the condensed water in the boiler is formed and how ZOZEN Boiler uses the condensed water in the boiler.

The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
In thermal fluid systems, the choice of materials for valves, piping, gaskets, and other components is critical to ensure the system's integrity, efficiency, and safety. These materials must be compatible with the thermal fluid used, capable of withstanding the operating temperatures and pressures, and resistant to corrosion. As a leader in industrial boiler manufacturing, ZOZEN Boiler emphasizes the importance of selecting the right materials for each component of a thermal fluid system. Below ...
Heavy oil, often referred to as residual oil or furnace oil, is a by-product obtained after the refining of crude oil. This type of oil is characterized by its high viscosity and dense structure, making it more challenging to burn than lighter fuels. However, advances in technology have made it possible to utilize heavy oil efficiently in boilers, providing a significant source of energy for various industrial processes.
Boilers Suited for Heavy Oil

Typically, a steam boiler should receive servicing at least once per year. Any kind of safety failure with a boiler can have serious consequences, and so a yearly inspection will help to spot any safety issues that need to be addressed. Servicing your boiler on a regular basis can also help you to save money on repairs. If you spot a problem during routine maintenance, there's a good chance you'll be able to fix it at a much cheaper cost than if the problem goes unnoticed and becomes a larger and more serious issue.
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
