Patent Summary
A burner for annular vertical shaft kilns that produces a stable flame from solid powdered combustibles, particularly coal or biomass, in a combustion chamber with improved combustion rate and reduced refractory wear. The burner features a bluff body effect created by a central sleeve with a bore, surrounded by an annular channel for fuel injection, and a cooling jacket to maintain the sleeve's temperature. The design enables stable flame formation in sub-stoichiometric conditions, with the bluff body effect stabilizing the flame and the cooling jacket preventing overheating.
