Dedusting of the biomass boiler

We implemented a dedusting system for a biomass boiler using the G&G Ceramic JET filtration equipment manufactured by us. A G&G Ceramic JET filter unit with ceramic filter inserts with a maximum operating temperature of 900 ° C was used. Regeneration of filter ceramic rods takes place automatically by pulses of compressed air. We guarantee TZL emissions at the outlet of the filter unit up to 10 mg / m3.

The filter unit is equipped with a filter hopper heater to reduce condensation inside the filter unit. The dumping of ash from the filter unit is solved by means of a tight double flap located on the pyramid hopper. The flue gas fan is supplied by the investor.

For a boiler output of 1000 kW A filter unit was used for 256 pieces of ceramic filter rods with a total filter area of ​​72 m2. Ceramic rods ensure that the filter medium is not burned by the fuel. We use ceramic filters for flue gas dedusting for boilers up to 2 MW.

For higher outputs, we install electrostatic precipitator units from SaveEnergy, which we exclusively represent in the Czech Republic and Slovakia.

Exhaust filters

G&G Ceramic JET-B flue gas filters are designed for dedusting flue gases generated by the combustion of solid fuels in combustion sources. Due to their design, the filter units are used for dedusting biomass combustion boilers.

The basic characteristic of filtration devices is the resistance to hot particles and residues of unburned fuel, which occur in the flue gases during the combustion of biomass. The flue gases entering the filter unit are directed to the lower part of the filter device by means of an internal partition so that the housing of the filter unit is evenly heated. The flue gas passes through the filter medium upwards into the clean filter chamber and then through the outlet opening to the flue gas fan.

Ash collection takes place in the standard design into integrated ash tanks, which the boiler operator periodically empties. For boilers in continuous operation, the filter units are equipped with an automatic ash removal system. At lower installation heights, the removal of dust is solved by means of a movable bottom of the filter and then by a screw conveyor to the dustbin.

The filtration device is thermally insulated over the entire casing and is equipped with an electric heating cable for tempering the filter housing and preventing condensation of flue gases at the moment of starting or stopping the boiler at a low flue gas temperature.

The filtration equipment does not have to be equipped with a pyramidal dust hopper due to the lower installation dimensions for the possibility of installation directly into the boiler room.
