Energy Conservation relating to the CO Boiler of Residual

05/07/2015 · Examples include COG sensible heat recovery for drying coking coal, sintering ore sensible heat recovery for low pressure steam production or hot air sintering, and hot blast stove flue gas sensible heat recovery for preheating gas. However, the recovery and utilization rate of middle grade residual energy and heat is 30.2% . For low grade residual energy and heat (lower than 200 °C), there is almost no recovery

Heat recovery from boiler blowdown - content.spiraxsarco.com

Heat recovery from Boiler Blowdown Increase energy efficiency and cut costs by recovering heat and water from TDS blowdown Steam boilers need to be blown down to control the level of Total Dissolved Solids (TDS) in the boiler water. Usually, a TDS system opens a valve to discharge boiler water when the conductivity rises above a pre-set limit.

whilst minimising the energy used heating air. Burners combust boiler fuel to generate heat. Burners and their control systems can have a major impact on overall boiler efficiency. The level of improvement that can be achieved by upgrading burners depends on the age and design of the boiler system. Fuel savings of 3%-5% may result from upgrading
