• JFE Engineering: Cement Waste Heat Recovery Solution Provider in India

Waste Heat Recovery

WHR System

The WHR system consists of heat recovery boilers for the Pre-heater (PH) and the Cooler section of the Cement plant, a steam turbine, a generator, and other auxiliary equipment.

  1. Exhaust gas from the suspension PH, is sent to the Pre Heater boiler, (also referred PH Boiler or SP Boiler). JFE Engineering India can offer both horizontal and vertical boiler design for the PH Boiler.
  2. Exhaust gas from the Air Quenching Cooler is sent to the Air Quenching Cooler boiler (AQC Boiler).

Maximization of heat recovery by incorporation of

  • Dual pressure system including Economizer (as may be required)
  • Mid tap from AQC

3. The superheated steam produced in each boiler drives the steam turbine generator in order to produce electric power.

4. JFE India can offer WHR solution either based on Steam Rankine Cycle or Organic Rankine Cycle

The main advantages of a WHR system:

The system uses only Waste Heat from the cement production’s residual process gas in order to generate electricity, which means there is no additional fuel requirement. WHR system maximizes the energy efficiency of the cement plant while also generating Green power that inhibits CO2 emissions. WHR system won’t affect Cement plant normal operation

Key Equipment

PH Boiler

PH Boiler

Features

  • The PH Boiler is of vertical configuration with horizontal tube arrangement. The exhaust gas from the kiln passes through the Pre-heater columns and enters the Boiler.
  • Depending upon the plant layout, if required, JFE India can also offer horizontal PH Boiler (with vertical tubes).
  • Considering the amount and type of dust content in the exhaust gas, the heating tubes selected are bare and equipped with efficient dust dislodging system.
  • Such dust dislodging is achieved by state-of-the-art rapping system which hammers the tubes to release the dust deposited on it by the incoming exhaust gases.

AQC Boiler

AQC Boiler

Features

  • A vertically configured AQC Boiler shall be installed for recovering the heat from the cooler exhaust gas.
  • JFE India’s technology is uniquely positioned for handling gases with highly abrasive dust at high temperature. To avoid any heat loss, tie in point of heat recovery system is proposed immediately after the cooler vent outlet (prior to the Electrostatic Precipitator as well as fresh air bleed).
  • The AQC Boiler would comprise mainly of a de-dusting system (integral type) followed by various heat exchanger sections of the boiler.
  • The AQC Boiler has finned tube construction designed to accept moderate dust
