Shandong Senmei board factory 2 sets of Shanghai Sifang Boiler Factory 10t / h steam chain boilers, in order to make full use of the production process of waste - wood flour, placed a high-pressure fan, sent through the air duct powder A boiler is arranged above the front arch of the hearth to directly inject the wood powder into the hearth and burn it for less than six months.
