fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boilers fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.

Making sense of boiler ratings - HPAC Magazine

However the heat lost from the boiler jacket, piping losses and pick-up allowances are assumed to contribute to the buildings heating load. This assumption means the boiler and piping is thought to be located in the heated space. The Heating Capacity rating will always be higher than the IBR Gross output rating because of this factor.

Design of Waste Heat Boilers for the Recovery - SpringerLink

An analysis of test results from BSC arc furnaces has been used to provide a typical pattern of waste heat rejection. This data provided a waste heat rejection of 200 kWh/tonne for a 170 tonne furnace. The waste heat boiler application is discussed in relation to the scrap preheating technique currently under consideration in BSC.
