摘要： PROBLEM TO BE SOLVED: To improve the heat exchanger efficiency of a catalytic combustion heater. SOLUTION: The catalytic combustion heater comprises fins 17B in boiling portions 31B for zoning the same into a plurality of small channels arranged perpendicularly to the surface thereof in Fig., which boiling portions are positioned in the midstream of a fluid-to-be-heated channel 3 contacting the intensively heated midstream portion 21B of a combustion gas channel 2 to boil the fluid to be heated. The fins 17B comprise through holes 170B for allowing adjacent small channels to communicate to each other, reducing pressure difference among the small channels to stabilize the surface of fluid and allowing bubbles expanding by bumping to escape to adjacent small channels so as to prevent the wall surfaces of the channels from being covered by gas layers poor in heat transfer efficiency, thereby allowing heat concentrated in the boiling portions 31B to be effectively transferred to the fluid to be heated.

摘要： PROBLEM TO BE SOLVED: To provide a fluid heating apparatus provided with a premixing burner, in which a thermal load of a high temperature section is small, even if the apparatus is miniaturized to eliminate the possibility of burning loss, and production of NOx is suppressed. SOLUTION: Heat transfer pipe group 12, 14 are disposed in a housing 3, and a premixing burner 1 is provided between a combustion chamber 8 and a mixing chamber 9. A cooling pipe 24 is provided in a gap 23 between a first porous plate 21 serving as a burner slit and a lower second porous plate 22, through which a fluid to be heated before supplied to the heat transfer pipe group 12 flows as a cooling fluid. Hereby, a premixed gas of combustible gas flowing into the combustion chamber 8 after passage through a small hole and a combustion assistant gas and atmosphere in the combustion chamber 8 is cooled, so that even when temperature of a combustion flame and combustion gas is lowered, burning loss of a high temperature section is prevented, to also reduce occurrence of thermal NOx. As an application of the fluid heating apparatus 2, if, for example, a cooling fluid circulating in a fuel cell for example is employed as a fluid to be heated, since warming of the fuel cell is rapidly advanced to produce rated electric power at an early stage.

摘要： PROBLEM TO BE SOLVED: To provide a catalytic combustion heating device capable of completely demonstrating a catalytic performance, excellent in its heat exchanging efficiency and high in its reliability. SOLUTION: A heat exchanger 1 has a fuel gas passage 11 in which fluid to be heated flows and many tubes 5 having catalyst carrying fins 51 connected together on their outer surfaces. Thus, the fluid to be heated is heated by the oxidizing reaction of the fuel gas. A controller 6 controls a support gas supply device 4 so as to increase the quantity of supply of support gas mixed and supplied to the fuel gas when the temperature of combustion exhaust gas detected by a temperature detector 8 disposed at the exhaust gas port 13 of the fuel gas passage 11 has become at most dew point temperature determined by the composition of fuel gas. Thus, a part of the oxidizing reaction heat is carried downstream to raise the temperature of combustion exhaust gas and the decrease of catalytic activity due to the condensation of steam is prevented.

摘要： PROBLEM TO BE SOLVED: To ensure a safe catalysis combustion heating apparatus with short starting time in which the entire apparatus can be activated in an early time with a simplified construction while preventing a fin and a tube from being locally heated and uncombusted gas from being exhausted. SOLUTION: Many tubes 5, through each of which a fluid to be heated flows, and to each of which a catalyst carrying fin 51 joins, are disposed in a combustion gas flow passage 11 of a heat exchanger 1, and the fluid to be heated is heated by oxidization of fuel gas. A controller 6 restricts heat transfer into the tube 5 by regulating the flow rate of the fluid to be heated to a small value until the temperature of the fluid sensed by a temperature sensor 8 disposed in the vicinity of an outlet of a flow passage 55 for the fluid to be heated exceeds predetermined temperature, e.g. the boiling point, and the temperature of the fin 51 is raised in an early time to the catalyst activation temperature. After the boiling point is reached, the flow rate of the fluid to be heated is increased up to a prescribed value to promote heat transfer to the fluid to be heated whereby desired high temperature gas is ensured while preventing the temperature of the fin 51 and the tube 5 from being high needlessly.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst combustion heater which can exhibit catalyst capacity sufficiently and is excellent in heat exchange efficiency and is highly reliable. SOLUTION: A large number of tubes 5 having insides that function as heating object fluid passages and catalyst carrying fins 51 joined to external surfaces are arranged in a fuel gas passage 11 of a heat exchanger 1 so as to heat the heating object fluid by the oxidative reaction of fuel gas. A controller 6 controls a combustion assisting gas feeder 4 so as to increase the quantity of the supplied combustion assisting gas mixed and supplied into the fuel gas when the temperature of the combustion exhaust gas detected with a temperature detector 8 installed in the exhaust gas port 13 of the fuel gas passage 11 reaches a dew point determined by the composition of fuel gas or lower. Hereby, a part of oxidative reaction heat is carried downstream, and it raises the temperature of combustion exhaust gas, thus the drop of the catalyst activity caused by the condensation of stream is prevented.
