SZL series shop-assembled water-tube steam boiler is a type of double-drum horizontal chain grate boiler. The main components of this boiler are assembled into two large parts in factory, ie. the upper part (the boiler proper) and the lower part (the chain
Get A QuoteThe research aims to design and construct a new mixed vertical boiler (fire tube – water tube) with three gas passes. The strength of this technological innovation is in the best use of the thermic transmission receiving fluid (hot water, steam, thermal oil), this due to its multipurpose function of three steps using alternative fuels (Diesel, Liquid Petroleum Gas LPG, natural gas), by
