Precautions of Biomass Boiler in Practical Application

In the actual application of the biomass boiler, if you want to play an efficient and environmentally friendly performance, you need to focus on a number of key links. Each step from fuel selection to equipment maintenance affects the stable operation and service life of the boiler.

Fuel management is the primary concern. The biomass fuel has a variety of types, with large differences in moisture and density. Ensure that the fuel is dry during use. Too high moisture will reduce the combustion efficiency and may cause coking problems; When different fuels are mixed, attention shall be paid to the ratio to avoid the combustion stability being affected by uneven heat value. Meanwhile, the fuel storage environment shall be dry and ventilated to prevent mildew and deterioration.

Coking and ash deposition shall not be ignored during equipment operation. Alkali metals and chlorine elements contained in biomass fuel are easy to produce ash and slag after combustion, and coke is formed when they are attached to the furnace and heating surface. Regularly clean the ash deposit and coke deposit in the furnace and flue, or the heat transfer will be hindered, the heat efficiency will be reduced and even the equipment will be damaged. In addition, pay attention to the operating state of the feeding system to avoid poor feeding due to fuel caking and bridging.

Emission control is also important. Although the biomass boiler is relatively environmentally-friendly, it will still produce more particulate matter and carbon monoxide when the combustion is not sufficient. Air volume and fuel supply shall be reasonably adjusted to ensure full combustion; Timely maintain dust removal, desulfurization and other environmental protection devices to ensure up-to-standard emission of pollutants. Patrol inspection of equipment shall be carried out daily to check whether pipes and valves leak, monitor pressure, temperature and other parameters, and timely handle any abnormality found.

In a word, the efficient operation of the biomass boiler is inseparable from scientific fuel management, careful equipment maintenance and strict emission control. Only by paying attention to the key points in the actual application, can it continuously play the value of green energy equipment.
