24h, fines-fired furnaces with regulator and blower

KWM-S boiler

19-350 kW
  • KWM-S heating furnaces (with regulator and blower) are the new generation of unattended heating furnaces working in twenty-four-hours mode designed for highly efficient combustion of fine coal.
  • Very high power efficiency of this kind of heating furnaces, reaching 86% results in the lowest running expenses.
  • Additional advantage is insignificant destructiveness for natural environment.
  • Employing controller and blower combined with upper combustion and distribution of air stream with use of nozzles makes the process of combustion similar to producer system with simultaneous combustion of produced gases, what characteristic symptom is blue flame.
  • One-shot fuel fill-up is enough for about twenty four hours, however this period may lengthen depending on outside temperature and insulating power of the building.

PRODUCT DESCRIPTION

Application

KWM-S heating furnaces were designed to be used in central heating installations in flat buildings, trade pavilion, workshops, on farms, in glass-houses, schools, etc. Available power rating: 19-350 kW. Heating furnaces were granted ecological attestations and conformity certificates according to standard PN-EN 303-5 issued by the Institute of Chemical Processing of Coal in Zabrze and certificates issued by Technical Supervision Office for WE – module B1 project investigation.

Operation principles

Body of the KWM-S heating furnace consists of furnace chamber and heat exchanger both made of high quality attested steel. Furnace has cuboidal shape, on its walls there are air nozzles and on the bottom there is water grate made of attested thick-walled pipes.

KWM-S heating furnace was equipped to heat exchanger which is located in the rear part of the body, behind the furnace and was designed as two (19-100kW) or four (125-350kW) upright convection ducts, depending on power rating. Such design let on obtaining effect of spontaneous cleaning of convection ducts and effect of chimney soot fallout into collection chambers which are secured by revision flaps located on a side of the furnace.

Additional elements of the KWM-S heating furnace (two-duct) are pipes (water tubes) located in convection duct and in two- and four-duct there are furnace commutators located in the upper part of the furnace. They have significant influence on heating furnace efficiency.

KWM-S heating furnaces are equipped to thermal-resistant wide furnace door and fill-up door with purpose-made thermal gasket in the front of the heating furnace body. Whole body was covered with high-grade thermal insulation which is protected by steel casing. KWM-S central heating furnaces must be installed according to standard PN-91/B-02413 and BN-71/8864-27 concerning open vent water heating installations safety and open vent expansion tank.

Exploitation

Exploitation of KWM-S heating furnaces is cyclical. It consists in one-shot fill-up with fine coal, firing it up from the top with use of small amount of paper and wood and starting up controller and blower. After having obtained previously set temperature the blower turns off and controller automatically turns into hold mode. The blower shall be started again when temperature falls under set value. When the fuel is burnt-out the controller turns off automatically. In order to launch the heating furnace once more it is necessary to remove ash from ash pan and furnace chamber and fill up fuel tank and fire up the heating furnace.
