Abstract: A device and method for controlling fuel-air ratio during combustion of ground in a coal power plant, including pneumatic delivery of ground coal to the burners and feeding combustion air to burners while controlling the combustion air and the amount of carrier air. A high reliability of control combined with low maintenance of the air mass measurement devices is achieved. This is achieved by a measurement device for measuring the amount of combustion air which, according to correlation measurement, evaluates the triboelectric effects on sensors. Between 0.1 mg and 10 mg of fine-grained particles of a diameter between 20 ?m and 200 ?m are introduced per m3 air into suctioned fresh air, which is carried out during the starting of the firing system. This is done by correlation measurement that evaluates triboelectric effects on sensors, arranged in series in carrier air stream in direction of flow of the carrier air.

Abstract: A control system for a waste processing apparatus controls entry of a predetermined quantity of waste into the processing chamber via air lock whenever the level of waste in the chamber has fallen sufficiently to accommodate the new waste, and this is detected by a suitable detector. A second detector may be located upstream of the first detector to enable the flow rate of waste through the processing chamber to be calculated.

Abstract: An apparatus and method is provided for discharging ash from a plurality of fossil-fuel boiler hoppers through actuator opened gate valves by opening only selected gate valves during a given discharge cycle and bypassing other hoppers. The time required to discharge a given hopper is determined and compared with a desired time range that would be required to discharge the hopper, if the hopper was filled to a desired percentage. Opening of a given hopper during subsequent cycles is based on a comparison of the actual discharge time with a desired discharge time range. If the actual discharge time is less than the minimum time of the desired time range, a time increment is assigned to the given hopper, and the hopper is bypassed on subsequent cycles until the assigned time increment has expired.

Abstract: A method of wood waste disposal which regulates factors such as the amount of wood residue being fed to an incinerator at any given time so that wood residue from a mill is processed promptly and efficiently without compromising the efficient operation of the incinerator. The wood residue is separated into at least two fractions, the first fraction being directed to a storage bin for later use as required, and the second fraction being directed to the incinerator. During periods of slack feed of the second fraction to the incinerator, portions of the first fraction, as required, are directed to the incinerator as make-up, in order to maintain an optimal range of incinerator conditions by manipulating the volume and flow of wood residue in cooperation with manipulating other factors.

Abstract: The invention is a system for detecting the level of slag in a solid fuels gasification reactor. In this invention a pokerod is extended into the quench chamber of the reactor, and pulled back to a retract position, in a timed sequence. The timed sequence is initiated by an electronic controller unit, in combination with an air pressure regulator, a solenoid valve, a double chamber air cylinder, and two sensor switches. The end of the pokerod that moves into the quench chamber is designed to contact the solid slag without penetrating the material itself. If the pokerod makes contact with the slag material, the controller sets off an alarm to warn the operator of slag build up in the reactor.

Abstract: A control module in a hot surface ignition system includes a microcomputer programmed to provide a pre-selected igniter warm-up time period for enabling the igniter to heat up to gas ignition temperature during normal system operation, and is further programmed to provide, for test purposes only, an accelerated igniter warm-up time period which is shorter than the pre-selected igniter warm-up time period but sufficiently long for enabling the igniter to heat up to a temperature sufficiently high to ignite gas. The program for providing the accelerated igniter warm-up time period is automatically executed in response to a unique signal effected by the control module in conjunction with a detachably connected test device.
