Moss gasifier boiler designs range in size from 150 - 1,739 HP (60,000 lbs./hr.) and design pressures from 15 - 950 PSIG and superheated temperatures up to 950° F. Moss gasifier systems have proven their ability to burn dry or wet fuel at a very low firing rates making it particularly suitable for heating or process applications. Our system provides superior combustion technology by providing large furnace volumes (low BTU/cu. ft. of heat release), multi-zone grate underfire air system, multi-port overfire air system with high turndown capabilities and is operated by our superior combustion control system. The gasifier system can be installed on any of our boiler pressure vessels including watertube, hybrid, firetube and HRSG (heat recovery steam generator) boilers. Our gasifier combustion system provides very low emissions and can also be used for retrofits of existing boiler systems.

Gasifier boiler systems offers the following features and benefits:

  • Capable of burning wood, biomass, corn, municipal solid waste (MSW) and DDGS fuels.
  • Burns wet or dry fuels.
  • Low emissions.
  • Very safe system to operate particularly when burning dry fuels.
  • High turndown capabilities.
  • Four (4) different grate designs provide flexible design and capabilities.
  • Multi-zone grates provides air to desired areas in chamber for clean gasification.
  • Overfire air system provides thorough burnout of gases formed in lower chamber and fans are supplied with variable frequency drives and optional oxygen trim system.
  • Automatic ash removal system.
  • Fully automatic and user friendly PLC control system.
