摘要： A flow splitter distributes solid particles flowing in a fluid, such as coal particles flowing in air, through a piping system. The flow splitter includes a divider housing having an inlet configured to connect to an upstream pipe and having an outlet configured to connect to a plurality of downstream pipes, e.g., by way of a divider head. A divider body is mounted within the divider housing. A plurality of divider vanes is included, each extending from the divider body to the divider housing. The divider housing, divider body, and divider vanes are configured and adapted to reduce non-uniformity in particle concentration from the inlet and to supply a substantially equal particle flow from the outlet to each of the downstream pipes.

摘要： A particle fuel burning furnace has an upper combustion chamber for holding a pile of particle fuel and burning the same from the bottom thereof. The furnace also includes a lower combustion chamber for afterburning combustible gases given off by the burning of solid fuel in the upper chamber and a series of spaced apart vertically-extending passageways arranged in a row and interconnecting the upper and lower chambers for communicating the combustible gases from the upper to the lower chamber. A first improved feature relates to a particle fuel delivery control device which operates an auger for filling the upper chamber with particle fuel to a desired level. A beam of light is transmitted and reflected between a photoelectric cell and reflector respectively of the device. When the particle fuel pile has grown in height during filling to the desired level the light beam is interrupted and filling is terminated. A second improved feature relates to a particle fuel diversion structure positioned in spaced relationship above and overlying the row of passageways. The structure forms a horizontal slot which extends laterally from the passageways which prevents particles of fuel from falling through the passsageways and relocates the flame which burns the particle fuel pile from the bottom to a region away from the passageways.

摘要： An automatic bed level control system is provided for furnaces which burn a material on a bed, such as chemical recovery furnaces and the like. Optical sensing means sense light emitted by the burning of the bed material and provide a signal which varies as a function of the intensity of the sensed light. The sensing means are structured and oriented to respond to light emanating only from a particular, vertically limited zone in the furnace, such that variations in the intensity of the sensed light are indicative of variations in bed level. The signal provided by the sensing means is then used to regulate some bed level controlling parameter, as for instance primary air flow.

摘要： A design and method of operation for the floor of solid fuel boilers is described. The combustion region includes a stepped-floor that improves combustion in the lower furnace. In some embodiments, the fuel is moved between the steps of the floor by a gas, rather than by mechanical means, and the fuel is moved from an upper to a lower step as it is burned. In some embodiments, the steps are fixed steps having a layer of a refractory material.

摘要： Method and apparatus for sensing the overall and/or distribution of fuel weight disposed on the top surface of the grate of a grate-fired device and adjusting the fuel infeed as a function of the flow rate of steam generated by the boiler. A plurality of weight sensors are disposed remote from the grate at selected locations associated with the support for the grate and which provide signals which are convertible to useful representations of the overall weight and/or the distribution of fuel weight over the top surface of the grate in real time and independent of the forward movement of the grate and associated changes in the weight of the fuel on the grate at a given time.
