Operating Mode

A boiler house is typically the start of any industrial process that needs heat to function. The process heating system usually includes a number of specific requirements such as temperature, pressure, energy input, particulate and exhaust emissions limits, etc. These conditions need to be measured to ensure the boiler house performance & safety is in accordance with the set parameters. In most of countries those conditions are strictly controlled by the government to ensure the safety of the equipment and its operation.

As a result, boiler house monitoring is critical and must be optimised to comply with safety standards, maintain reliable operation, reduce operating costs and improve overall boiler house performance.

Babcock Wanson undertakes continuous research and development to create boiler operating modes to meet our customers’ changing needs. Babcock Wanson has developed an integrated monitoring and regulation package covering all the equipment in the boiler house, including the burner, boiler, exhaust gas emissions and water treatment. Babcock Wanson’s operating modes can also provide real-time monitoring and data logging of all relevant boiler parameters using our Operating Assistance Module (OAM) high integrity system.
