The furnace of a BLRB is generally taller than a utility or industrial watertube boiler of similar steam generating capacity, due to the sticky nature of the combustion gases. The pulp production capacity of a mill determines the size of a BLRB. For each ton of pulp, about 3,000 lbs of dry solids are generated.View More
2. Waste heat recovery systems. Waste heat recovery methods include capturing and transferring the waste heat from a process with a gas or liquid back to the system as an extra energy source .The energy source can be used to create additional heat or to generate electrical and mechanical power .. Waste heat can be rejected at any temperature; conventionally, the higher the temperature, theView More
Monowall or membrane wall; Tangent Tube. In tangent tube arrangements, small diameter tubes are closely pitched together to form an arrangement backed by three layers, namely - refractory, insulation and boiler casing. The problem with this arrangement is that, in case of tube failure the welded repairs become a bit difficult to carry out.View More
