FSE Energy can provide the full scope of engagement to deliver a turn-key power or cogeneration plant including engineering, design, fabrication, procurement, construction, balance of plant work and aftermarket services.

A variety of stoker grate combustion options are available depending on the operating parameters and fuel specified. Common options include vibrating, traveling, stationary and reciprocating grates.

Benefits

  • Low capital costs – FSE Energy has the reputation for offering the highest quality equipment at the best possible value. Customers using stoker grate combustion technology often realize the lowest possible initial capital costs.
  • Low maintenance costs – Grate technology offers simple operation and reduced maintenance costs.
  • Less refractory – As it requires less refractory in the furnace and boiler, emergency and planned outages have reduced maintenance costs.
  • Availability – Grate technology provides the lowest available system downtimes of any combustion technologies.
  • Fuel flexibility – Grate technology is the best option for fuels with moisture content under 55%, low ash fusion fuels and high alkali content fuels which cause slagging in BFB/CFB systems.

When to Choose a Stoker Boiler

  • Low capital costs are paramount
  • Low operations & maintenance cost are targeted
  • When a customer expects to burn fuels with either of the following conditions:
    • Low ash fusion temperatures in the fuel
    • High alkali content in the fuel

  • Agricultural residue (bagasse, stover, rice hulls)
  • Bark
  • Biomass
  • Coal
  • Landfill gas
  • Natural gas
  • Oil
  • Paper mill sludge
  • Peat
  • Poultry litter
  • Process wastes (furniture manufacturing, construction & demolition)
  • Recycled paper facility sludge
  • Syrup from ethanol facilities with high alkali contents
  • Tire-derived fuels
  • Wood waste (forestry, pulp and paper)
  • And other fuels
