Biomass Boilers Maintenance Precautions

June 16, 2021

Biomass boilers tend to coke during the fuel combustion process, which leads to poor furnace fires and burned grates in the boiler. The following are the biomass steam boiler maintenance precautions.

1. The biomass steam boiler must be cut off the power supply, must relieve pressure.
2. Biomass steam boiler burner should be removed from the boiler body every two months, carefully remove carbon and dust and other foreign objects. Phototube lighted surface wipe once a month, the fuel filter to always maintain clean and filter function; carefully clean the filter inside the oil pump, do not destroy the gasket. Burners must not idle without oil, so as not to damage the oil pump.
3. Biomass steam boiler water level meter should always be kept clean, open the cleaning valve once a day to flush to ensure that the water level is clear, biomass steam boiler safety valve is triggered once a day to prevent rust failure.
4. Biomass steam boiler stop running for a long time, the power should be cut off, and good maintenance work.

The biomass boilers produced by Zhongzheng can be divided into four series: SZL series double-barrel longitudinal chain grate boiler, DZL series single-barrel longitudinal chain grate boiler, DHL series biomass angle-tube chain grate boiler and SHL series double-barrel bulk chain grate boiler.

SZL series water-cooled arch, membrane water-cooled wall assembly boiler is a new type of water tube assembly boiler developed exclusively by our company and integrated with the advantages of bulk boiler arch, it will be a large chain grate boiler combustion system water-cooling technology and membrane water-cooled wall technology cleverly applied to the assembly boiler, is the first of its kind in China, the boiler using a double-barrel longitudinal arrangement, combustion method for the chain grate. The combustion system of SZL series assembled chain grate biomass boiler includes coal hopper, chain grate and grate transmission device.

ZOZEN biomass boiler has wide applicability of fuel, which can be applied to biomass pellets, wood chips, palm shells, straw and other fuels; meanwhile, ZOZEN boiler reasonably designs the relevant structure according to the characteristics of different fuels to ensure the efficient energy saving and stable operation of the boiler; it solves the problems of ash formation, coking, wear and tear, burning front arch, burning hopper and so on.

ZOZEN biomass steam boiler is highly automated with digital integrated controller, which can automatically control the combustion conditions according to the user’s setting, easy and convenient to operate, automatic ignition, automatic feeding, automatic ash cleaning, which is as convenient as the operation of oil and gas boilers.It adopts inverted “alpha” arch technology to improve the combustion characteristics of fuel, and the coal type is widely adaptable.
