Filed: 1985-11-20
Abstract: PURPOSE:To simplify the constitution of a decision circuit by constituting the decision circuit with a counter and using an FF and a NOR gate to update the counter. CONSTITUTION:When a signal n=i is outputted from a counter 42, an input signal selector 1 selects an input signal Si and gives an output Sout and a signal interruption detection signal selector 43 of the decision circuit 4 selects a signal interruption detection signal DWNi at the same time and gives input to the FF 2. When the signal DWNi is '0', since the output of the NOR gate 6 is at an L level in this state, the counter 42 loads a signal n=i to keep the signal (i).

Title: Device for supplying solid and liquid mixed fuel, and fluidized bed type combustion furnace
Inventor: MURAKAMI TOSHIO
IPC: F23C10/22
Filed: 1992-09-29
Abstract: PURPOSE:To enable fuel of high viscosity to be uniformly divided to flow to a fuel nozzle by a method wherein a total cross sectional area of pipes just after the pipe is branched is set to be larger than a cross sectional area of an upstream side pipe before branching. CONSTITUTION:A total cross sectional area of a pipe 3b just after branching of a pipe 3 is set to be larger than a cross sectional area of an upstream side pipe 3a before branching. Due to this fact, it does not happen that pressure for pushing fuel fluid forcedly fed by a fuel supplying pump 5 is locally concentrated and locked, resulting in that the pipe 3 is not clogged. A reduced angle thetaat the downstream side of the pipe 3b is restricted to enable a clogging of fuel fluid within the branched pipe 3b to be prevented. In addition, since a flowing direction of the fuel fluid is set to be vertically and upwardly flowed, no locking phenomenon at the branch part A occurs under an influence of gravity. With such an arrangement as above, it becomes possible to divide the pipe 3 stably without any clogging in it, and further to supply fuel smoothly to a combustion furnace such as a fluidized bed type boiler and the like.
