FIELD: heating system.
SUBSTANCE: powdered solid fuel boiler with rotary type cycle heater comprises a furnace; a rotary type cycle heater which comprises a heat exchanger main housing; a drive gear; a separative element fixed on the heat exchanger main housing along the centroidal axis that divide the heat exchanger main housing into at least one pair of the receptor chambers, where each pair of the receptor chambers placed diametrically opposite towards the centroidal axis; a heat-transfer fluid that is received in the receptor chambers respectively, and made of nonmetallic solid material, with the heat-transfer fluid equipped with the catalyst denitration bed; moreover, a fire gas run the 50-80°C temperature after the heat exchange by means of the rotary type cycle heater; a gas tube of the fire gas with the connected with the furnace upside input and connected with the rotary type cycle heater output; an air circuit for the air delivery into the other receptor chamber of the plug-together receptor chambers.
EFFECT: boiler efficiency upgrading.
