Blower type burner automatic regulator - controls gas and air supply to ensure optimum mixture composition over working range by air pressure sensor

摘要

The gas and air mixt. fed into a blower type burner has a mixt. ratio control system. Gas supply is automatically adjusted in relation to the air supply to ensure optimum combustion. The mixture composition is regulated over the whole working range by a relatively simple system. The air supply is adjusted to the max. value and the gas supply is adjusted to a max. value ensuring optimum combustion. The gas supply is varied over the whole working range in relation to the given air supply by a regulator responding to the mixt. composition. Air is supplied by a blower (25) and a pressure sensor (21) in an air channel (1) transmits a signal to a reference value regulator (23) which actuates the gas flow restrictor valve (27).
