The food processing needs the steam or hot water to assist the production and improve the efficiency. Usually, the food plant needs the small tonnage boiler, so the coal-fired boiler is not recommended.
Percussive sounds ("banging," "hammering," or "knocking") and vibrations in boiler drums or pipes are serious operational anomalies that demand immediate attention. At ZOZEN, we engineer our coal-fired boilers (like the SZL water-tube and DZL fire-tube series) to minimize these risks, but they can still arise due to operational or system issues. Here are the primary causes and ZOZEN's approach to mitigation:

The importance of a coal-fired chain grate boiler sample is reflected in the following aspects:
Technical and Design Reference: The coal-fired chain grate boiler sample provides engineers and designers with detailed technical parameters and design conditions, including the boiler's basic capacity, environmental conditions, operating pressure, and temperature range, and other key information. This data is crucial for ensuring the rationality and safety of the boiler design.

In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
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.
The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
