PBM125 - 1 1/4" ID Pipe Burners and Venturi, (with Optional support Legs) Burners are for High Pressure, Low Pressure Propane or Natural Gas, include a 1 1/4" Female NPT venturi and a welded cap on the other end. We stock (4) different lengths of pipe burners 32", 44", 56" and 68" which are measured from the threads of the pipe burner to the ... Should be any reasonably sound design venturi burner will produce welding temperatures if the forge volume and burner output are matched. Generally given, 350cu.in. for a 3/4" venturi burner. That is a thing a person finds at both ends of the venturi burner spectrum... Larry Zoeller's 3/4" "modified side-arm" and Rex Price's 3/4" T-Rex. Mike
Combustion Venturi (CCV) burner design is described along with full-scale burner test data from the Riley Research coal burner test design. In addition, recent overfire air system operating experience is discussed. Field test data from a 400 MW coal-fired utility boiler retrofitted with new overfire air NOx controls are presented. Fives offers a wide range of robust cast iron and stainless steel premix combustion products for use on many high temperature industrial heating applications such as ceramic kilns, refractory lined metal ladles, copper launders, glass forehearths, crucible melting furnaces, impingement heating and as pilots for larger burners.
