摘要： PURPOSE:To realize a low NOx by sucking exhaust gas by means of a preheating air of great momentum and burning a primary fuel in a mixture of the preheating air and the exhaust gas of low oxygen concentration which are mixed due to an agitating effect of an ejector. CONSTITUTION:A preheating air supply port 6 opened to an rear end surface of a primary combustion chamber 2 is provided and restricted at its outlet portion to form an ejector 7 which sucks exhaust gas from an opening provided over the entire circumference of a rear end portion of a peripheral wall of the primary combustion chamber 2. Thus, the exhaust gas is effectively sucked from an exhaust gas sucking passage by a preheating air of great momentum from the preheating air supply port 6, so that a primary fuel is made to burn in a mixture of the preheating air and the exhaust gas of low oxygen concentration which are mixed due to an agitating effect of the ejector 7. Accordingly, it is possible to suppress a primary combustion at a low temperature even if the mixture is high in temperature. Therefore, a low NOx can be realized.

摘要： PURPOSE:To remarkably improve the corrosion resistance of a heat transfer surface to a corrosive liq. by thermally spraying Ti, a Ti alloy, or TiO2 separately or compositely onto the heat-transfer pipe for heating the corrosive liq. CONSTITUTION:The heat exchanger 6 consisting of a heat-transfer pipe 7 and fins 8 is dipped in the highly corrosive liq. 3 such as the Ni plating Watts soln., and high-temp. steam is supplied from an inlet 7a to heat the liq. 3 and discharged from an outlet 7b. An inexpensive metallic base material 12 such as mild steel and stainless steel is used for the heat-transfer pipe 7, and the surface is blasted by a steel grid to form a fine-ruggedness surface 12a. The layer of an Ni-base alloy is formed thereon in about 80mum thickness as a substrate layer 13, and then Ti, a Ti alloy, or TiO2 are thermally sprayed separately or compositely thereon in about 120mum thickness to form a corrosion-resistant layer 14. Finally, a sealing layer 15 consisting of a synthertic resin based on epoxy, urethane, 'Teflon(R)', silicone, etc., is formed on the surface of the corrosion-resistant layer 14 to seal the layer 14, and the heat-transfer pipe 7 having excellent corrosion resistance is produced.

摘要： PURPOSE: To provide a regenerator for an absorption hot and chilled water generator capable of being reduced in size and having short starting time without altering combustion gas temperature in a heating unit. CONSTITUTION: A plurality of flues 31 to 33 having burners 34 to 36 are provided, and the peripheries of the flues 31 to 33 are brought into contact with regeneration liquid via heat transfer walls. Thus, combustion gases of the flues are sufficiently heat exchanged with regenerated liquid. The combustion gas temperature of the outlets of the flues shorter than those of conventional flues is lowered to the same degree as that of prior art, and the regenerated liquid is heated by smoke tubes provided in a regenerated liquid tank by a liquid tube 40 provided in a vertical or horizontal direction perpendicularly to a combustion gas passage 39.

摘要： PURPOSE: To prevent the contact of a burner tile surface with a primary flame and hence prevent a heat spot from being formed by supplying a secondary fuel in a thin film shape to an outer periphery of the primary flame turning in a combustion chamber in the vicinity of the tip end of the combustion chamber. CONSTITUTION: A body part 7 of a burner coupled with a base end of a combustion chamber 1 includes an air supply pipe 9 of a central part, a primary fuel supply pipe 10 around the air supply pipe 9, a turning air injection cylinder 1 around the pipe 10, and an air chamber 12 provided on the outer periphery of the turning air injection cylinder 11. Air supplied to the air chamber 12 through an air supply duct is injected circumferentially from an air injection hole 2 in the turning air injection cylinder 112 to form a turning air stream, and part of the air is injected from the air supply pipe 9 to the center of a primary combustion injection hole 8 whereby the primary fuel is made cylindrical to promote the mixing of the fuel and air and hence restrict formation of a heat spot.

摘要： PURPOSE:To reduce the sound of exhaust at a high sound absorption rate without bringing in deterioration with time, as an exhaust resistance is being made to be small by making a constitution in which a pitch type carbon fiber is used as a sound absorbing material. CONSTITUTION:A muffler 5 is connected communicatingly with an engine 1 through an exhaust manifold 3 and the 1st exhaust pipe 4, and at the same time, the 2nd exhaust pipe 6 discharging exhaust gas into atmosphere, is communicatingly connected to the muffler 5. At the muffler 5, the respective one ends of the 1st, the 2nd exhaust pipes 4, 6 are inserted into a casing 7 in a state in which they are on different levels, and a curl shaped pitch type carbon fibre 9 is inserted, as a sound absorbing, material, into the inside of the casing 7 forming a flow route for a high temperature exhaust gas in a pressurization state, and thus, a constitution is made. As a result, the energy of sound is excellently damped by means of this pitch type carbon fiber 9.

摘要： PURPOSE:To stablizedly repeat explosive combustion in a pulsating burner, by properly determining the interlocking ratio of a rotor rotated at a fixed period of time by fluidizing combustion exhaust gas, to a check valve mechanism to prevent reverse flow of the gas. CONSTITUTION:Relative formation phases of flow-path holes (a) and (b) on the side of a valve body and flow-path holes (a') and (b') on the side of a valve seat to the rotating period of a rotor 8, and the transmission ratio of a gear interlocking mechanism 9 are determined in such a manner that both valve mechanisms 6 and 7 are opened at the time 9of explosion in order to check combustion gas from flowing reversely from a combustion chamber 1, and those valve mechanisms 6 and 7 are also opened when fuel and combustion air are sucked into the combustion chamber 1 by the exhausting inertia of combustion exhaust gas after explosion, utilizing the rotor 8 rotated in a constant period of time by steady fluidization of combustion exhaust gas by each explosive explosive combustion, as the rotor 8 is interlocked with both valve mechanisms 6 and 7. With such an arrangement, explosive combustion can be repeatedly continued stably in a pulsating burner.
