Abstract

There is provided a combustion appliance with a safety device. An oxygen partial pressure sensor made up of a transition metal oxide or rare earth metal oxide is normally disposed in a position in which the excess air ratio downstream of a flame formed by a burner can be detected and, at times of abnormality, within the flame. The resistance change of said oxygen partial pressure is detected and the combustion is stopped when incomplete combustion occurs due to oxygen depression, clogging of the primary air orifice of the burner or clogging of the combustion chamber with the products of combustion.

Catalytic combustion process using supported palladium oxide catalysts

Patent Kennelly, T; Farrauto, R

A process for starting a combustion system to catalytically combust a gaseous carbonaceous fuel with air in a combustor in the presence of a palladium oxide-containing catalyst is described, which comprises: (a) predetermining a decomposition onset temperature at which the palladium oxide-containing catalyst decomposes at an oxygen partial pressure equal to that found in the combustor; (b) predetermining a reformation onset temperature at which the palladium oxide-containing catalyst will, at said same oxygen partial pressure found in the combustor, reform into palladium oxide after being subjected to the decomposition temperature; (c) utilizing a flow of hot gases from a pre-burnermore »« less

Air demands of residential combustion appliances

Conference Hayden, A - Proc., Annu. Meet., Air Pollut. Control Assoc.; (United States)

Combustion appliances generally require air both for combustion itself and for dilution. The dilution device, known as the barometric damper on an oil system or as the draft hood on a gas system, is located downstream of the furnace heat exchanger and takes no part in the combustion nor heat exchange processes. It is primarily designed to isolate the combustion system from outside pressure fluctuations. However, it does represent the major air requirement of the heating system, typically at lead 3 times the air required for combustion. New oil- or gas-fired combustion systems, either under development or just reaching themore »« less
Blending of hydrogen in natural gas distribution systems. Volume II. Combustion tests of blends in burners and appliances. Final report, June 1, 1976--August 30, 1977. [8, 11, 14, 20, 22, 25, and 31% hydrogen]

Technical Report

The emerging ''hydrogen economy'' is a strong contender as one method to supplement or extend the domestic natural gas supply. This volume of the subject study ''Blending Hydrogen in Natural Gas Distribution Systems'' describes combustion studies to determine the maximum amount of hydrogen that can be blended in natural gas and utilized satisfactorily in typical appliances with no adjustment or conversion. Eleven pilot burners and twenty-three main burners typical of those in current use were operated on hydrogen-natural gas mixtures containing approximately 8, 11, 14, 20, 22, 25, and 31 percent, by volume, hydrogen. The eleven pilot burners and thirteenmore »« less
