摘要： PROBLEM TO BE SOLVED: To provide a gas combustion apparatus capable of easily and accurately setting gas type, and realizing an appropriate control of combustion in response to calorific power and primary gas pressure of gas to be used.
SOLUTION: In the gas combustion apparatus, a gas pipe 10 for supplying fuel gas to a burner 2 is provided with a flow rate sensor 11 for detecting mass flow rate of the fuel gas and a gas flow rate control valve 12 for adjusting fuel gas flow rate. At the pilot run time, comptroller 13 opens the flow rate control valve 12 to a predetermined opening, calculates a calorific power of the burner 2 at this time based on a inflow water temperature, tapping temperature, inflow water amount, or the like, and obtains a characteristic of calorific power-valve opening of the fuel gas based on the determined calorific power and the valve opening of the flow rate control valve 12.

摘要： PROBLEM TO BE SOLVED: To provide a combustion device wherein a stable combustion state and a large turndown ratio are obtained. SOLUTION: The combustion device 1 is roughly composed of a main component 5, a sub component 6 and a burner port member 3. Four plate bodies 7, 8, 10 and 11 composing the main component 5 and the sub component 6 are provided with uneven parts by press-molding metal plate bodies. In the combustion device 1, void parts and blocked parts are formed by lapping the plate bodies, and the void parts are communicated with each other to form a gas passage 22 (a main passage) and a rich gas passage 73 (a sub passage). The main component 5 and the sub component 6 are fitted together by caulking them in a lapped state from a lean gas mixing piece 22a to a recessed part piece 40b, and a rib part 14 protruding in an outside direction is formed by this.

摘要： PROBLEM TO BE SOLVED: To eliminate the difficulty with prior art that in a combustion apparatus employing a rich/lean fuel combustion system non-combusted components are exhausted upon ignition to cause odor of gas and be uncomfortable, and further provide a feeling of unrest that gas might be exploded. SOLUTION: A combustion apparatus 1 comprises a burner body 10 and a burner port member 13. The burner body 10 is fabricated by laminating four metal plate structures 15, 16, 17, 18. In the combustion apparatus 1, fuel gas introduced from a rich gas introduction hole is branched to a lean fuel gas flow passage at a branch portion therein, and a curved passage is provided on a lean fuel gas flow passage after the branch section, and further the lean fuel gas flow passage after the branch section is longer than the rich fuel gas flow passage after the branch section. Therefore, physical distances reaching burner ports of two kinds are different, and after a flame is produced from an auxiliary burner port low concentration fuel gas is injected from a main burner port. For this, fire is rapidly transferred also to low concentration fuel gas injected from the main burner port, and less unburnt components are exhausted.

摘要： PROBLEM TO BE SOLVED: To avoid the occurrence of abnormal combustion by detecting the trouble of an open/close valve before combustion and enable combustion operation by the remaining open/close valves excluding the troubled open/close valve. SOLUTION: In this gas combustion apparatus, a fuel gas is regulated by a flow control type gas control valve before supplying and the downstream side thereof is branched by the plurality of open/close valves for switching a combustion capacity. If the detected flow amount value of a gas flow sensor varies when a main solenoid valve is opened with the first/second open/close valves 61a and 61b closed, one or both of the first/second open/close valves are abnormal in closing and, if it does not vary, the valves are determined to be normal, and output an open select signal to the first open/close valve. If the detected flow value varies, the first open/close valve is determined normal and, if it does not vary, it is determined to be abnormal in closing and outputs open switch signals to a second open/close valve by closing the first open/close valve. When the detected flow value varies, the valves are determined normal, and if it does not vary, the second open/close valve is determined to be abnormal in closing. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：为了通过检测燃烧前的开/关阀的故障来避免异常燃烧的发生，并且能够通过剩余的打开/关闭阀除了故障的打开/关闭阀来进行燃烧操作。解决方案：在该气体燃烧装置中，燃料气体在供给之前由流量控制型气体控制阀调节，其下游侧由多个用于切换燃烧能力的开闭阀分支。如果当第一/第二开/关阀61a和61b关闭时主电磁阀打开时检测到的气体流量传感器的流量值变化，则第一/第二开/关阀中的一个或两个关闭异常，如果不变化，则将阀确定为正常，并向第一开/关阀输出打开选择信号。如果检测到的流量值变化，则第一开/关阀被确定为正常，并且如果不改变，则确定关闭时异常，并通过关闭第一打开/关闭阀将打开的开关信号输出到第二打开/关闭阀，关闭阀门当检测到的流量值变化时，阀被确定为正常，并且如果不改变，则确定第二打开/关闭阀在关闭时异常。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a gas combustion device provided with a gas flow rate control valve of such type that a valve element is operated by a stepping motor and enabling use of the gas flow rate control valve for a plurality of types of gases in common.
SOLUTION: The gas flow rate control valve capable of obtaining the maximum capacity (the maximum input) at predetermined number of steps S in reference gas is used by using the gas having the lowest unit heat generation amount as the reference gas among types of gases whose use as fuel gas is scheduled in a controller of the gas combustion device (see Fig. 3 (a)). Unit heat generation amount of use gas supplied actually is compared with unit heat generation amount of the reference gas to change an excitation system of the stepping motor and change a drive amount of the stepping motor per step so that heat generation amount per step becomes the same based on the ratio (see Fig. 3 (b)).
