    Windbox – A chamber below the grate or surrounding a burner, thru which air under pressure is supplied for combustion of the fuel. Windbox pressure – The static pressure in the windbox of a burner or stoker. Zero governor – A regulating device that is normally adjusted to deliver gas at atmospheric pressure within its flow rating. Sources Learn More

  • windbox design of burners - Ignition, Combustion and

    The overall performance of a power plant depends significantly on how fuel and combustion air enter the furnace. Large fossil fuel boilers can have up to 100 individual burners that inject fuel and air. The proportion of flow through each of these plays an important role in the efficiency of the combustion process. By properly designing the combustion system, plant emissions of NOx and CO can Learn More
