摘要： PROBLEM TO BE SOLVED: To rapidly detect the occurrence of flashaback in order to perform a stop before a combustor is damaged by sensing the occurrence of the flashback by using a plurality of optical fibers and photodetectors. SOLUTION: A combustor 1 contains a plurality of flame nozzles 12a-12e to generate flame. The flame nozzles 12a-12e are monitored by using fiber optical elements 24a-24e containing optical fibers through which a light signal is sent to photodetectors 14a-14e. The photodetectors 14a-14e feed an electric signal to a multiplexer 18 and the multiplexer 18 transmits data to a signal processor 20 before the multiplexer is operated by a gas turbine controller and monitor 22. When light is detected by the photodetector 14a-14e at a level to indicate the presence of flame in a test region where no flame is present, the information is transmitted to the controller and monitor 22 through the signal process 20 and this way turns OFF the combustor 1.

摘要： PROBLEM TO BE SOLVED: To provide a gas heating and cooking device of low cost in which consumption power is low and it has a function to prevent gas from being flowed out due to extinguishing of a flame at a burner. SOLUTION: Each of a first safety valve 2a and a second safety valve 2b is normally opened or closed in cooperation with an opening or closing operation of each of a first device plug 7a and a second device plug 7b. For example, when a first burner 6a performs a normal ignition, a first thermo-couple 5a is heated by a flame and the first thermo-couple 5a may generate a thermo- electromotive force. When a control part 1a of a controller 1 detects this thermo-electromotive force, a control part 1a flows a holding current for holding an opened state of a first safety valve 2a to the first safety valve 2a through a cell 3. If a flame at the first burner 6a is extinguished, the thermo- electromotive force of the first thermo-couple 5a is eliminated, so that the control part la prevents a holding current for holding the opened state from being flowed from the cell 3 to the first safety valve 2a.

摘要： PURPOSE:To provide a superior heat-resistance, a high flame diminishing performance and enable passage of combustible gas at high flow rate with a safe and single quenching element by a method wherein the quenching element is made of heat-resistant ceramic porous material having some contious voids. CONSTITUTION:As heat-resistance ceramic material to be used in a quenching element, CaO, MgO, SnO2, ZnO, SiO2, Al2O3, ZrO2 and TiO2 are utilized. Ceramic powder has a particle diameter of 20mum or less in order to facilitate sintering during its baking work, organic porous material is distributed and kneaded with water to form plastic soft clay. This clay is formed into a certain shape, dried to form a green body, the green body is preliminary heated and the porous forming material is ignited and oxidized, thereafter the material is baked at such a temperature as one capable of being baked and then a porous sintered material having some communicating holes with narrow distribution of porous diameter is attained. This sintered material is formed as the flame diminishing element 4. With such an arrangement, the quenching element of large-sized sintered material for high flow rate with a less pressure loss can be easily attained. The quenching element 4 is foxed and engaged with a hollow part 2 within each of an inlet port member 10 and an outlet port member 11.

摘要： PURPOSE:To avoid such trouble as incomplete combustion due to clogging of burner ports by preventing falling matters such as combustion oxides, dust, etc., from entering the burner port. CONSTITUTION:One of upward burner ports 1 facing each other is covered with a combustion plate 2 leading to the burner ports 1 to prevent falling matters such as combustion oxides dust, etc., from directly entering the burner port 1. As the falling matters are accommodated in a pocket 3 that is located between and below the burner ports 1, the falling matters that pile up are kept from entering the burner ports 1.

摘要： PURPOSE:To reduce NOX installing in parallel a number of ejection bodies having an ejection hole in the upper part with flame port boards between, installing a flame retention flame ejection hole to the ejection body at the end of a burner and laying out a flame retention formation board outside, and carrying thick and thin combustion by means of the ejection bodies and the flame port boards in a captioned burner for a household small combustion device. CONSTITUTION:Wide flame port boards 3 having a laterally bored slit flame hole 4 are inserted and installed in parallel between ejection bodies 1a to 1c having an ejection hole 2 in the upper part where the ejection holes 2 and the flame ports 4 are laid out in a zigzag manner. A flame retention ejection hole 6a is formed on the ejection body 1 at the end of a burner while a flame retention formation board 5 is installed outside. The ejection bodies 1a to 1c are burnt in a low partial pressure state of oxygen so that NOX may be inhibited while the flame port boards 3 are cooled by excess air so that NOX may be inhibited.

摘要： PURPOSE:To reduce NOX by laying out an enriched mixed fuel gas ejection body on both sides of a steep slope hill-shaped ejection body having a laminar ejection section in the central upper part and an ejection hole on both sides by way of a clearance in terms of a captioned burner of a household small combustion device. CONSTITUTION:A hill-shaped ejection body 1 is formed where it is provided with a laminar ejection hole 5 in the central upper part and a laterally slit- shaped ejection hole 6 on a steep slope side wall 2 on both sides. Air or thin mixed fuel gas is supplied thereto. A second ejection body 3 is laid out on both sides by way of a clearance section 4. An ejection hole 7 is formed on the second ejection body 2, to which enriched mixed fuel gas is supplied. In this construction, the enriched mixed fuel gas flows out from the clearance section 4 upward and it is burnt in a lower partial pressure state of oxygen. As a result, it is burnt in the early stage as a low NOX and rises so that it may be mixed with the ejected from the ejection hole 6 where unburnt sections are subjected to combustion, which attains stabilized combustion.
