Energy Tips Process Heating

Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow, or in practical terms, excess air resulting from combustion air supply and air leakage into the furnace. The excess air can be estimated by measuring oxygen percentage in the flue gases. Waste Heat Recovery Heat losses must be minimized before waste heat recovery is investigated. Figure 2 highlights opportunities for energy
