The control further includes a microprocessor that periodically reads the CO sensor ... 06/01/06 - 20060115778 - Modular infrared irradiation apparatus and its corresponding monitoring devices Heat irradiation apparatus (1) defined in terms of the following:—Refractory flexible irradiation module (7) comprising stopping means which are high temperature resistant and avoid shadow zones and side losses of heat at the burning zone in the ceramic surface;—Employment of refractory flexible ceramic plates (15) having flexible pores which permit ... 12/01/05 - 20050266363 - Monitoring of flames using optical fibers and video camera vision system This invention relates to a flame detection method and apparatus. More specifically, this invention relates to a flame d on method and apparatus designed for simultaneously monitoring several flames of different types such as pilot flames and main flames of differing sizes and intensity. These detected flames can be in ... 11/10/05 - 20050250062 - Gaseous fuel burner An ejector, such as a venturi, facilitates the delivery of gaseous fuel to the combustion chamber of a burner. A blower forces air through the ejector, and the air flow produces a suction that draws fuel from a fuel inlet to produce a fuel-air mixture. The amount of fuel drawn ... 06/16/05 - 20050130087 - Signal processing technique for improved flame scanner discrimination A signal processing technique that allows the flame signal from a first source of flame and the flame signal from a second source of flame to be discriminated from each other when only both the first and second flame signals are viewed by the same flame scanner. The signal from ... ### FreshPatents.com Support |
