PRODUCTS AND SERVICES NEWS ABOUT US CONTACT Heat Recovery Steam Generators & Once Through Steam Generators – HRSG & OTSG Heat Recovery Steam Generators (HRSG) and Once Through Steam Generators (OTSG) generate saturated or superheated steam from recovery of heat from Gas Turbines or Diesel Engines. Steam can be used to cover heat demands, but unlike liquid heating mediums in WHRUs, steam is also suitable for extra power production in steam turbines or steam engines. Heat Recovery Steam Generators (HRSG) and Once Through Steam Generators (OTSG) generate saturated or superheated steam from recovery of heat from gas turbines or diesel engines. The steam can be used to generate additional electrical or mechanical power in steam turbines or steam engines. Together with the gas turbines, the Heat Recovery Steam Generators and the steam turbine forms a combined cycle power plant. Process heat demands can be covered by steam extraction and turns the Combined Cycle (CC) plant into a Combined Heat and Power plant (CHP). A Combined Cycle and a Combined Heat and Power plant will always maximize the heat recovery when process heat demand is varying, and the exhaust dampers will not by-pass exhaust and thereby avoid heat losses. The HRSG/OTSG is normally supplied as a complete module. The HRSG/OTSG module is more complex equipment relative to the Waste Heat recovery Unit as it contains several heat recovery sections in the exhaust path of the gas turbine, steam drum (HRSG only), boiler circulation pumps (HRSG only), piping, instrumentation, control valves, manual valves, auxiliary equipment – all assembled into a single lift skid designed for single lift onto our client’s installation. Techouse delivered the first HRSG module to offshore combined cycles plants in the late 1990s and have gained substantial experience in design and operation of these installations. Based on our experience and delivery track record we have optimized our HRSG offerings to meet our customers´ needs. PRODUCTS AND SERVICES NEWS ABOUT CONTACT
