Development of New Combustion Control Equipment. Application to a Modern Range of Gas Burners and the Resulting Savings. The Move Towards Permanent Closed Loop Combustion Control

摘要

Two types of combustion control equipment, one for premixed burners and the other for nozzle mixing burners, based on the same patented principle, are described. According to this principle, air/gas ratio is maintained by means of a simple mechanism through the motion of a single rotating organ. The low cost and small size of this equipment, coupled to its ease of use has facilitated the economic use of modern forced draught burners, both radiant and convective, alone or in groups. Substantial energy savings result from the constant air/gas ratio on installations so equipped, the safety in use being particularly appreciated by operators using manually controlled heating equipment. The addition of continuous combustion monitors to this control equipment will allow, by means of a microprocessor, an almost instantaneous compensation for changes in air quality (temperature, pressure, humidity) or gas quality (temperature, pressure, Wobbe index).
