Advantage

    • Description:

      The SZ series shop-assembled steam boiler, adopts a double-drum water tube structure. The boiler body consists of upper drum, lower drum, water-cooled wall tube, convection tube bundle, downcomer, header, etc. The water-cooled wall tubes constitute the radiation heating surface of the furnace, the tube bundle between the upper drum and the lower drum constitutes the convection heating surface, and the economizer and air preheater are arranged at the tail.

      Kenuo Boiler can customize design the combustion devices  according to the calorific value, size, moisture, ash content, and ash melting point of the fuel, Select the suitable combustion type, fixed grate, chain grate, reciprocating grate, bubbling bed, circulating fluidized bed (CFB). Make the boiler applicable for various biomass fuels such as Biomass pellets, Biomass briquettes, Wood chip, Corn cob, Rice husk, Palm shell, Walnut shell, Cocoa shell, Cashew shells, Coconut shell, Palm fiber, Bagasse, Urban wood waste, Bark, Production wood waste, Olive pomace, Coffee grounds, etcdifferent-biomass-fuels
