4. Special design
(1) Adopt domestic and foreign advanced large furnace design
Increase the diametre of furnace on the basis of original traditional design.expand the surface of radiant heat exchange,mainly center on radiant heat exchange ,reduce the heat exchange burden during the second and third return,and make the fuel burning efficiently,reduce the harmful gas production. Besides,the spiral hearth in the high temperature area not only increase the area of radiant heat exchange, but also make a resistance to the smoke movement.have a obvious effect about radiation heat exchange.
(2) The spiral furnace design
Increase the overall strength of the furnace,make compensation for the heat exchange and shrinkage automatically,avoid the in-perfection of welded sew crack due to the change of tube plate heating stress.Therefore,boiler has strong adaptability about various of fuel,for example,heavy oil,light oil,natural gas,city gas.
(3) Improve heat transfer technology
Apply the technology of heat transfer from “the light of Harbin institute”.Adopt the design of efficient heat transfer screw thread pipe and optimize the smoke speed.The output and heat efficiency of boiler don’t decrease with the extend of operation time,thus achieve a compact structure with 10% overload capacity.
5. Boiler usage
1. Steam boiler can be used for food industry, such as Yuba food factory, suace paste factory,etc.
2. Biomass fired steam boiler can be used for wood processing factory,sugar mills,feed processing facory.
3. Coal fired steam boiler can be used for textile factory, printing and drying factory.
