摘要： A downflow hearth furnace includes a refractory-lined furnace lid. A burner is thermally coupled through the lid. A combustible material conveyor system communicates with an entry port. A variable speed motor driven rotatable combustible material disperser is positioned under the entry port and coupled to a rotation shaft. A refractory-lined furnace shell has a top edge mating with a bottom edge of the furnace lid and can be raised and lowered between an open position and a closed position. A bed of gas-permeable heat resistant material suspended on a layer of filter material defines a bottom end of a hearth disposed above a plenum. An outlet duct communicates with the plenum and has a horizontal outlet flange. A fixed scrubber input duct has an inlet flange positioned to mate with and form a seal with the outlet duct flange when the furnace shell is in the closed position.

摘要： A furnace for wood log fuel having apparatus which automatically inserts the logs into the furnace combustion chamber. The log fuel is retained in a sloping ramp storage compartment. Electrical circuitry controlled by a thermostat operates to move a log into an elongated chamber from which a motor driven injector pushes the log into the combustion chamber through a doorway covered by a flexible, segmented flap covering and also a door which is pushed open by the advancing log. The presence of the log on a spring mounted grate operates certain switches to return the injection mechanism to its ready condition and also to operate a fan which provides combustion air to the combustion chamber. The reduced weight on the grate by the consumption of the log by the fire permits the grate to move to a position to re-initiate the log injection cycle. A standby gas fuel burner system is also provided and is controlled by the thermostat to operate when the log fuel heat is insufficient, such as upon the supply of log fuel becoming exhausted. An optional auger conveyor which operates under the control of dual timers for automatic discharge of ashes from the furnace is also disclosed.

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.
摘要翻译：颗粒燃料燃烧炉具有用于保持一堆颗粒燃料并从其底部燃烧的上燃烧室。该炉还包括一个下燃烧室，用于对燃烧在上部室中的固体燃料的燃烧产生的可燃气体进行后燃，以及一系列间隔开的垂直延伸的通道，其布置成一排并且互连上部和下部室，以使可燃气体从上到下。第一改进的特征涉及一种颗粒燃料输送控制装置，其操作用于将上部室的颗粒燃料填充到期望水平的螺旋推运器。光束在装置的光电池和反射镜之间传输和反射。当颗粒燃料堆在填充期间在高度上增长到期望水平时，光束被中断并且填充被终止。第二个改进的特征涉及一种以间隔关系定位的颗粒燃料转向结构，该排列结构位于通道列的上方并且上方。该结构形成从通道横向延伸的水平槽，其防止燃料颗粒落下通过通道并重新定位火焰，其将颗粒燃料桩从底部燃烧到远离通道的区域。

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： The height of a cone, mound, or pile of fuel in the combustion area of a furnace is controlled by arranging a temperature sensor on a portion of a probe normally penetrating the burning fuel. When the fuel burns down sufficiently to expose the sensor to direct heat from the pile, a signal is sent from the sensor to a relay which opens a valve mechanism to feed fuel into the furnace. A timer may be used to limit the amount of fuel delivered.
