Solid fired HAG uses Wood wastes (such as bar, chips saw dust) Agricultural wastes (such as husks, ground nut shells, cotton stacks, soybean shells etc) or lignite, coal solid waste as fuel. Solid fired HAG are extremely efficient and have high heat transfer area. Solid Fired HAG comes in two models i.e. vertical as well as horizontal and has huge edge over other types HAG due to low operational cost.
