According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more ...
and air flow, as well as by the manner of fuel feed. c.i. Cross-feed stokers . In cross-feed stokers, the fuel is dumped by gravity from a hopper onto one end of a moving grate, which carries the fuel into the furnace and down its length. Cross-feed stoker boilers are also termed travelling-grate stoker boilers.
15-06-2018· To apply the ROM method, the present grate boiler is simplified into three zones according to the flow diagram shown in Fig. 14a, i.e. the lower mixing zone where PA mixes with fuel, the middle recirculation zone where OFA is located and internal flue gas recirculation occurs, and the upper post-combustion zone where the combustion of combustible species is almost completed.
