Ceramic tubes, inlet vanes and outlets for industrial mechanical dust collectors.
Tubes, spin vanes and outlets for mechanical collectors.
Cast in silicon carbide to fit the collector you already run.
In abrasive fly ash and process dust, multicyclone tubes cast in silicon carbide outlast the cast iron and Ni-Hard parts they replace, because the ceramic is far harder than the dust that grinds through metal. Blasch SiClone components in OXYTRON and ALTRON are made as drop-in replacements for the iron parts of existing mechanical collectors, in 6, 9, 12 and 24 inch sizes, and weigh well under half as much. One of the largest SiClone collectors, with 24 inch tubes, went into a biomass-fired plant in 2017 and was still in good condition in spring 2020.
A mechanical collector splits the gas into many small cyclones. In each one, the spin vanes at the inlet set the dust spinning and throw it against the tube wall at a shallow angle, where it grinds along the metal until the wall is gone.
A cast iron tube with a hole still runs. The dust that passes the hole skips the separation and leaves with the gas, so emissions climb before anyone opens the collector.
Surface and shape matter as well. The ceramic parts are cast with a smooth surface and close roundness tolerances, closer than a metal casting holds.
A multicyclone with a worn tube keeps running, but the dust that slips past it goes up the stack, so tube life is an emissions question before it is a maintenance question.
Each part replaces its iron counterpart one for one, in each of the four tube sizes Blasch makes.
The body of each small cyclone, cast smooth inside, where most of the wear takes place.
The vanes that set the gas spinning and take the first hit from the incoming dust.
The central tubes that carry the cleaned gas out of each cyclone.
Engineered rings that hold the ceramic parts in place and make installation simpler.
Power plants and industrial boilers burning coal, biomass, bagasse, wood or hog fuel, pulp and paper mills, cement plants with clinker dust, steel and iron ore pelletizing plants, mining and milling, coke processing, materials handling, brick plants and palm oil extraction.
The parts handle gas above 1,200 °F. OXYTRON is an oxide bonded silicon carbide made for abrasion at temperature. Oxide bonded silicon carbide
Two plants have documented their switch: an iron ore pelletizing plant, and a chemical plant that had a complete ceramic collector built. SiClone in a chemical plant
Large process cyclones use the same principle at a bigger scale, see vortex finders and thimbles. Erosion in FCC cyclones is covered under scrubber and cyclone linings, the whole range under wear products. Ceramics for power generation
They are made to replace the iron parts of existing mechanical collectors by tube size and design. Give us the collector model and tube size, and the engineer confirms the fit.
No. They weigh well under half as much as the iron parts and seat in engineered mounting rings, so a crew handles them more easily than castings.
It can. Cast iron cones are rough and slightly out of round, and the precise ceramic surface keeps the separation closer to what the collector was designed for.
Send the collector model, the tube size and the dust it handles. A Blasch engineer matches the SiClone parts to your collector.
