A recovery boiler is a power plant subsystem used to capture energy that would otherwise be lost in waste products that were not completely combusted. This energy is recycled to the primary energy generating system to produce more power. For this reason, this equipment may alternatively be referred to as a heat recovery boiler or as a waste heat recovery boiler. The main requirement for its use is that the system’s waste products have sufficient recoverable energy to drive the primary power generating equipment.Waste Heat Recovery Steam boilers may be used in the power systems for a variety of industrial equipment.
Waste recovered for further combustion in a recovery boiler is usually a gas, a liquid, or a combination of the two. Processes generating these types of wastes include metal refineries, petrochemical processing plants, and other industrial plants operating at high temperatures. Solid material may also be used, though this is less common. The most notable example of solids used in recovery boilers is in papermaking.
Benefits from sinter-cooler waste heat recovery system
Direct benefits: The recovery process will add to the efficiency of the process and thus decrease the costs of fuel and energy consumption needed for that process.
Indirect benefits:
Reduction in Pollution: Thermal and air pollution will dramatically decrease since less flue gases of high temperature are emitted from the plant since most of the energy is recycled.
Reduction in the equipment sizes: As Fuel consumption reduces so the control and security equipment for handling the fuel decreases. Also, filtering equipment for the gas is no longer needed in large sizes.
Reduction in auxiliary energy consumption: Reduction in equipment sizes means another reduction in the energy fed to those systems like pumps, filters, fans,...etc.
