We have been making stokers since 1913 to burn conventional and unconventional fuels. We built our first oscillating grate water-cooled stoker in the 1950's. Ash Discharge is Automatic Ash is automatically discharged from the grate during timed oscillating intervals. We integrate the grate, water cooling tubes, air plenum, and drive mechanism in a free standing shop-assembled module isolated from the boiler. Integral Grate and Air Plenum for Tight Air Seal Grate surface and air plenum are a single unit that oscillates together, with no seals to separate or leak.
Combustion air reaches the fuel through the grates for thorough burning.
A Cost-Effective Retrofit to Traveling Grate Spreader Stokers Oscillating vertical flow technology does not require a sloped grate surface, so retrofits to stokers with horizontal grates can be made without pressure part modification.
