Title: Fuel gas production apparatus and burner
Inventor: KUDO HIDEFUSA
IPC: F23D14/48
Filed: 1994-10-11
Abstract: PURPOSE: To combust fuel gas at high temperature with high efficiency by mixing primary fuel gas produced by heating or combusting fuel and air with use of a turning flow and/or a spiral flow and hence decomposing hydrocarbon in the primary fuel gas to carbon and hydrogen. CONSTITUTION: Pressurized air is injected from an air nozzle 20 at an upstream position of a gas flow-down pipe 18. Hereby, part of an air flow along a convex curved surface of the tip end of a mixed flow forming member 32 disposed between the tip end of the air nozzle 20 and the gas flow-down pipe 18 is exfoliated at an annular groove part and flows into an annular groove part 70 together with primary fuel gas to become a spiral flow. Part of the air flow bursting out from the annular groove part 70 strikes a step 40 and becomes spiral and turning flows when it passes through a narrow region between a taper side peripheral surface 40A and a corner part of the step 40 to provide a flow flowing out to the gas flow-down pipe 18. For this, a reaction between air and the primary fuel gas is promoted.  Hereby, fuel gas from fuel such as an alcohol can be combusted at a high temperature with high efficiency.

A main control system obtains the mean value of the reflected light quantities from the surface part of the original from the data on high-order five sheets out of the A/D converted data and compares it with an initial value (reference value). In the case the mean value of the reflected light quantity is lower than the initial value, as the compared result, the voltage of an exposure lamp is corrected by the main control system and an AC control system according to the degree of a difference between them.  When the voltage of the exposure lamp attains an upper limit, it is held and developing bias voltage is corrected by the main control system in accordance with the difference between the mean value of the reflected light quantity and the initial value. When the developing bias voltage also attains the upper limit, it is held and a warning is given to a user.
