摘要： PROBLEM TO BE SOLVED: To start catalyst combustion appropriately by rapidly starting a device without increasing heater power and device size even if the fresh air temperature is low in a catalyst combustion heating device using methanol as a fuel for starting. SOLUTION: A device is provided with a first fuel gas supply means for supplying methanol from a methanol supply path 31 to a heat exchanger 2 with a catalyst along with a burning-supporting gas from a burning-supporting gas supply path 7 by vaporizing the methanol and a second fuel gas supply means for supplying hydrogen in a hydrogen storage container 81 to the heat exchanger 2 with a catalyst along with the burning-supporting gas from the burning-supporting gas supply path 7 from a hydrogen supply path 8. When the fresh air temperature is low on starting, first the second fuel gas supply means is operated for increasing the temperature of the catalyst on the surface of a fin 23 due to the catalyst combustion heat of hydrogen where a temperature for burning the catalyst is low and switching is made to the first fuel gas supply means when a temperature for burning the catalyst of methanol is reached, thus starting the device at an early stage.

摘要： PROBLEM TO BE SOLVED: To obtain a safe catalytic combustion heater having a high heat exchanging efficiency capable of rapidly increasing an output to a specified value while preventing an excess temperature rise of an oxidizing catalyst in the case of stepwisely increasing the output from a steadily operating state. SOLUTION: A tube 2 having a fluid-to-be-heated channel therein is arranged in a channel 11 of a fuel gas containing combustible gas and a combustion supporting gas, and many fins 21 carrying oxidizing catalysts are provided on an outer periphery of the tube 2. An outlet temperature detector 7 for detecting an outlet temperature of the fluid to be heated is disposed in a discharge tube 42 as an outlet of the fluid channel. In the case of stepwisely increasing an output, a flow rate of a combustion supporting gas is first increased by a flow controller 6. Thereafter, a flow rate of the fluid is increased to a specified value based on a change of an output temperature of the fluid, and a flow rate of the combustible gas is increased to a lower predetermined value than the specified value, and thereafter the flow rate of the combustible gas is increased tote specified value. Thus, the output can be rapidly raised while preventing the excess temperature rise of the catalysts.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst combustion heating device, safe and high in a heat exchanging efficiency by a method wherein the amount of heat generation due to catalyst reaction is regulated optimally to improve heat transfer performance to fluid to be heated and prevent the over-heating of members, such as fins, tubes or the like. SOLUTION: A multitude of tubes 2, whose inside is utilized for the passage of fluid to be heated, are arranged so as to be layered in a fuel gas flow passage 11 provided in a vessel 1. The advancing direction of the fluid to be heated is reverse to that of fuel gas. The amount of heat generation in the upstream side of the fuel gas flow passage 11 is controlled optimally by a method wherein an oxidizing catalyst layer is formed directly on the outer surface of a tube 2 in the layer 2A of uppermost upstream of the fuel gas flow passage 11, in which the fluid to be heated is changed into gas state, while the oxidizing catalyst layer is formed on the outer surface of fins 21, connected to the outer periphery of the tube 2, in the downstream side of layers 2B-2E, whereat the fluid to be heated is liquid state or boiling state.

摘要： PROBLEM TO BE SOLVED: To provide a catalytic combustion heating device which can prevent the deterioration of its heat exchanging ability or overheating of the external surface of a tube even when the ending point of a liquid boiling section moves to the upstream side and for which it is not required to strictly control the liquid boiling ending point of a fluid to be heated. SOLUTION: A heat exchanger with catalyst is constituted by arranging many tubes 2 through which a fluid to be heated is made to flow in parallel in a casing 1 and forming oxidation catalyst layers on the surfaces of fins 21 provided on the outer peripheries of the tubes 2. Coil-like members 5 are inserted into the tubes 2 positioned in a liquid boiling section 2B of the flow passages of a fluid to be heated which are formed in the tubes 2 and, when the vapor flow of the fluid to be heated is introduced to the liquid boiling section 2B, the increase of thermal resistance is suppressed by promoting the mixing of the vapor flow by rotating the coil-like members 5. Therefore, the excessive temperature rise of a catalytic combustion heating device or the deterioration of the heat transferring ability of the heating device can be prevented by accelerating the heat transfer to the vapor flow from the internal surfaces of the tubes 2.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst combustion heater having a safe heat exchanger with catalyst of high heat exchanging efficiency without the abnormal temperature rise of fins or tubes. SOLUTION: In a heat exchanger 200 with catalyst, many catalyst carrying fins 201 are connected to tubes 202 in which fluid to be heated flows. When combustible gas supplied together with combustion air from a fuel supply part 100 comes into contact with the surfaces of the catalyst carrying fins 201, an oxidizing reaction is generated to generate heat and the heat is transferred from the fins to the tubes to heat the fluid to be heated. The resistance of heat transfer differs in the respective parts of the tubes 202 depending on the state of the fluid to be heated therein. For example, in a part where the vaporization of the fluid to be heated is completed, the resistance of heat trader is high, so that temperature becomes extremely high. The quantity of heat in the oxidizing reaction generated in the catalyst carrying fins 201 because of the catalyst is changed depending on the parts of the tubes 202. Thus, a locally abnormal temperature rise is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized EGT valve device with a high responsiveness. SOLUTION: When a current is carried to a solenoid part 13, a solenoid shaft 12 is pushed down to warp a reed valve 6D situated on a lower plate 6C, whereby the air of an atmospheric pressure chamber 9 is carried into a negative pressure chamber 8. Since a diaphragm part 6 is thus moved down by the differential pressure between both the chambers, and an EGR valve 4 is also moved down through a shaft 7, EGR gas quantity is reduced. The positions of the diaphragm part 6 and the EGR valve 4 can be quickly and used according to the change of the current-carrying quantity to the solenoid part 13. Further, since an air passage 5 is allowed to communicate with a space 17 through a hollow part 16, and the diameter of the EGR valve 4 is substantially equal to that of a piston 15, the force by the pressure difference between the EGR valve and the upper and lower surfaces of the piston is canceled. Therefore, the driving force to the valve 4 can be minimized even when the EGR gas quantity is increased, and the device can be miniaturized.

摘要： PURPOSE: To prevent 'high-speed heavy sound' which tends to occur during high-speed travelling of a car whose internal combustion engine is supported by a liquid seal engine mount. CONSTITUTION: A liquid seal engine mount effectively prevents vibration of engine from transmitting to a car body by damping the vibration by means of viscous resistance of incompressible fluid which passes through an orifice when a car travels at low-speed, but generates a high-speed heavy sound due to reduction of flowing volume of the fluid which passes through the orifice when the car travels at high-speed. Therefore, vibration damping effect is adjusted arbitrarily, by making piezoelectric boards 10 and 11 attached to a diaphragm board 12 by which a main fluid room 13 is divided from a sub fluid room 14, by applying arbitrary voltage to one piezoelectric board from a control circuit 19 or the like as well as detecting deformation of the diaphragm 12, in other words, pressure difference between the main fluid room and the sub fluid room by means of the other piezoelectric board, by controlling the pressure difference by making the diaphragm board 12 deformed in an arbitrary mode, and by controlling incompressible fluid flow which passes through the orifice from outside.
