摘要： PURPOSE:To restrict any accumulation of combustion gas and condensing liquid in a refrigerant heater having a refrigerant pipe disposed at an outer wall surface of main material of a heat exchanger by a method wherein at least downstream side heat transferring fins of an end part of a discharging pipe having a plurality of heat transferring fins is eliminated. CONSTITUTION:A flame belt 51 of high temperature from a combustion device 19 is flowed into an inner cage 49, combustion gas 53 is flowed between heat transferring fins 27 at an outer circumference of the inner cage 49 and heat of the combustion gas is transmitted to a refrigerant pipe 29 through the heat transferring fins 27. In the case that a low temperature heating range is applied, moisture content of the combustion gas is condensed within a heat exchanger 17 and the condensed liquid is flowed toward a lower discharging cap 23. An end part of the discharging cap 23 of the heat transferring fins 27 is eliminated and a clearance 47 is formed, so that the condensed liquid passes through the clearance 47, flows from a discharging port 25a to the discharging pipe 25 and finally the liquid is discharged out of a refrigerant heater. With such an arrangement, accumulation of condensed liquid can be avoided, corrosion of the heat exchanger 17 can be prevented and then a life of the heater can be improved.

摘要： PURPOSE:To make a force of combustion variable in a wide range while keeping the combustion efficiency at a high level by a method wherein the quantity of a fuel supplied to a combustion chamber of the main body of a burner is made variable and the flow rate of air for combustion flowing into the combustion chamber is controlled in accordance with the quantity of the fuel supplied to the combustion chamber. CONSTITUTION:In a pulse burner, a fan 11 is stopped when the degree of opening of a fuel flow control valve 10 is the standard one. When the degree of opening of the fuel flow control valve 10 is increased so as to increase a force of combustion, an opening degree signal is sent to a fan control element 12. Based on this signal, the fan control element 12 makes the fan 11 rotate normally and controls the number of rotations thereof to be the one corresponding to the degree of opening, i.e. the number of rotations corresponding to the quantity of a fuel flowing into a combustion chamber 1. When the degree of opening of the fuel flow control valve 10 is decreased below the standard one so as to reduce the force of combustion, the fan control element 12 makes the fan 11 rotate reversely to make it correspond to the reduced quantity of the fuel flowing into the combustion chamber 1 and controls the number of rotations to be corresponding to the reduced quantity. Accordingly, combustion in the amount of combustion corresponding to the quantity of the fuel is attained with the air ratio fixed substantially.

摘要： PURPOSE:To secure self-suction characteristics sufficiently by eliminating the case in which the combustion gas flowing backwards from a flow rate control valve many flow into a combustion chamber again by its own accord at the early period of suction. CONSTITUTION:A connecting pipe 22 which directly connects mutually the upstream areas of two flow rate control valves 7a and 7b is provided in air supply pipes 6a and 6b and in a supply air decoupler 2 with the connecting pipe 22 not in contact with the flow rate control valves 7a and 7b. With this arrangement the combustion gas flowing backwards from the flow rate control valve 7a is led to the connecting pipe 22 when the combustion chamber 4a is in the process of explosion and a combustion chamber 4b is in the process of suction and passes through the flow rate control valve 7b and is sucked into the combustion chamber 4b. At this time the combustion gas is sucked into the combustion chamber 4b with fresh air in the supply air decoupler 2 by the injector effect so that it is not necessary to feed fresh air under high pressure. When the inside of the combustion chamber 4b explodes and burns, the matters contrary to the above mentioned may occur, and it is possible to secure self-suction characteristics unique to pulse combustion.

摘要： PURPOSE:To increase a variable width of a thermal input and enable a stable pulse combustion to be carried out by a method wherein a mixing variable device capable of varying a mixing speed of fuel and air is arranged at a downstream side of a flow rate control valve within an air supplying passage and then the mixing variable device is controlled in cooperation with a degree of opening of the fuel flow rate adjusting valve. CONSTITUTION:Swirling devices 11a and 11b are arranged in downstream sides of flow rate controlling valves 5a and 5b within each of air supplying passages 3a and 3b connected to each of combustion chambers 2a and 2b. When the fuel flow rate is low, an angle of a vane 13 of each of the swirling devices 11a and 11b is set to a small angle in respect to a flowing direction under a controlling action of control devices 16a and 16b for inputting a degree of opening signal of a fuel flow rate adjusting valve 17. In turn, when a fuel flow rate is high, the angle of the vane is set to a larger angle. When the angle of the vane 13 is high, a mixing speed of fuel and air is increased and in turn when the angle is low, the mixing speed is decreased. As a result, it is possible to cause a phase between a heat generating speed and a pressure variation to be always approached to the same phase and then secure a vibrating energy required for continuation of a pulse combustion. Accordingly, it is possible to get an enlargement of a variable width of capability and a realization of the pulse combustion.

摘要： PURPOSE:To miniaturize an apparatus and stabilize combustion by a method wherein the tail pipes of respective combustion devices are directly coupled at the downstream and the connected to an exhaust pipe and respective air supply pipes are also directly coupled at the upstream and connected to an air inlet pipe. CONSTITUTION:Pressure changes generated by regular explosive combustion occurring in one combustion cylinder 10a are propagated in a tail pipe 11a and passes through a coupling part 12 and reaches the other combustion cylinder 10b through a tail pipe 11b nearly without attenuation. Consequently in the cylinder 10b a phenomenon with a phase opposite to the phase of the phenomenon in the cylinder 10a occurs. That is, when one cylinder is in an explosion process, the other is in an air supply process. As a result, efficient interference effect takes place between both cylinders 11a, 11b. By this constitution, the miniaturization of an apparatus and the stabilization of pulse combustion can be contrived.
