Dampers

Dampers

ENEVA damper valves are high-temperature-resistant mechanical equipment designed to control, direct, or bypass exhaust or flue gas flow in boilers, furnaces, gas engines, and process systems. Proper management of energy flow is critical for both process control and the efficient and reliable operation of waste heat recovery systems.

  • Proportional flow control, shut-off, or bypass operation
  • Design suitable for high temperature and flow rates
  • Low leakage and optimized pressure drop
  • Structure suitable for heavy industrial conditions

WHAT IS A DAMPER VALVE?

Damper valves (exhaust or flue gas dampers) are mechanical control equipment used to:

  • Open / close flow
  • Provide proportional (modulating) control
  • Direct flow between two different lines (bypass)

ENEVA damper valves ensure safe process operation in applications such as waste heat boilers, cement plants, power plant boilers, and ORC systems.

  • Installed on the gas line with single-blade or multi-blade configuration
  • Blade position is adjusted via actuator (electric or pneumatic)
  • Gas flow is restricted or directed as required
  • In three-way applications, one line opens while the other closes simultaneously
  • Designed based on low leakage rates and minimum pressure drop
  • Cogeneration and trigeneration plants
  • Boiler flue gas systems
  • Furnace and process stacks
  • Cement plants
  • Iron and steel industry
  • Petrochemical plants
  • Biogas and landfill gas facilities
  • Combined cycle power plants
