摘要： PROBLEM TO BE SOLVED: To provide a method for diagnosing the combustion state of a burner, capable of effecting rapid and efficient maintenance. SOLUTION: By regulating the openings of a fuel control valve VF and a combustion air control valve VA, having a known flow rate factor, a furnace temperature is controlled to a set furnace temperature with a combustion air ratio held at a preset prescribed value. When some of the temperature of fuel fed to a burner 3 and the measurement value of a pressure and a temperature of combustion air supplied to the burner 3 and the measurement value of a pressure, and when one of the measurement of the opening of a fuel control value VF or the measurement of the opening of the combustion air control valve VA, or the measurement of a combustion air ratio exceeds a tolerance value set at the set value of each of the measurement items, a measurement measured before it exceeds the tolerance value and respective measurement measured after it exceeds a given value are stored for a given time, based on the time when it has exceeded the tolerance value.

摘要： PROBLEM TO BE SOLVED: To provide a control method for a burner using a composite throttling calculation wherein a flow rate coefficient of the burner can be treated as a practically measured value matched to the state of a fluid. SOLUTION: A combustion control method for a burner is adapted such that: An equation, V=√ (Q2/(P0-Q2/N2)) is derived from a relationship between a relation among supply pressure P2 of a fluid at the front of a burner when burners 11A, 11B are used as a fixed throttle, a flow rate Q of the fluid, and a flow rate coefficient N of the burner, and from a relationship among difference pressure P0-P2 of the fluid across a flow rate adjustment valve when the flow rate adjusting valve is of a variable drawing, the flow rate Q of a fluid, and a flow rate coefficient V of the flow rate adjustment valve. Into the equation there are inserted a practically measured value of supply pressure P0 on a primary side of the flow rate adjustment valve, a practically measured value of supply pressure P2 at the front of the burner, and a flow rate coefficient V' of the flow rate adjustment valve calculated from a practically measured valve opening S' of the flow rate adjustment valve. Hereby, an actual flow rate coefficient N' of the burner is calculated, which is inserted into an equation, N'=V'√ (P0-P2)/√ P2.

摘要： PROBLEM TO BE SOLVED: To provide a line burner in which the amount of combustion can be easily altered. SOLUTION: A burner body 1 comprises a first member 2 including a mixture gas passage 3 and a concave holding part 5, both being communicated with each outer through a first slit 7, and a second member 10 removably attached to the holding part 5 of the first member. The second member comprises two main header constituent members 11 each having a through-hole 12 and a pilot header constituent member 13 disposed on opposite sides of the former member 11. A main nozzle N1 and a pilot nozzle N2 are held between tip ends of each constituent member and are fitted to a recessed portion. A main header H1 and a pilot header H2 are formed between the constituent members, and a second slit 14 communicating with the first slit is formed between both main header constituent members.

摘要： PROBLEM TO BE SOLVED: To manage operation states of respective processors in a lump by a single monitor even when plural controllers using different communication protocols are present. SOLUTION: When combining the plural processors 1A, 1B, 1C executing prescribed processing to manufacture a prescribed product, the controllers corresponding to the respective processors 1A-1C are provided. Control data on the controllers 1A-1C are transmitted to a separately provided monitor X to manage the operation states of the processors 1A-1C. The control data from the respective controllers 1A-1C are transmitted to data converters Ta, Tb, Tc once, the communication protocols are unified in the data converters Ta, Tb, Tc, and the control data are transmitted to the single monitor X.
