摘要： PURPOSE:To lower the manufacturing cost and to make a burner assembly compact in the title combustion apparatus, by combinedly forming a vaporizing chamber to the throat which mixed vaporized fuel with air. CONSTITUTION:A vaporizing cylinder 21 is monolithically formed externally around a throat 4. One end of a vaporized fuel introducing pipe 23 is opened to the vaporizing chamber 21, and the other end of it is connected to a nozzle 3. A liquid fuel being fed by a pump 7 through a fuel oil feeding pipe 8 is led into the vaporizing chamber 21 from a fuel inlet port 9. The fed fuel is vaporized in a moment of time because the inside of a vaporizing cylinder 21 is preheated by an electric heater 2. When the internal pressure in the vaporizing chamber 21 is raised by expansion of fuel by vaporing, the vaporized fuel is ejected into the throat 4 from the nozzle 3 via the fuel introducing pipe 23. A combustion air is sucked from the opening 13 at the bottom of it by a jet flow of fuel at the same time. The vaporized fuel is mixed with the air, becoming a mixed gas, going up to a burner head 5 ignited properly, forming flames 15. The vaporizing chamber is monolithically formed with the throat 4 in such a manner that the manufacturing cost of a burner assembly is lowered, and the spaces for a burner part and a vaporizing part can be reduced.

摘要： PURPOSE: To reduce the value of a thermal stress by one order, to prevent damage of a weld bead, and provide a liquid fuel evaporting device which is high in reliability, by providing a projecting ring to a part of a pipe.
CONSTITUTION: A part of a pipe 8 is formed in a manner that a projection ring 21 is radially expanded. Thus, since the projecting ring 21 of the pipe 8 is deformed by a relatively low force, even if a relative deviation is produced due to a temperature difference, a high thermal stress is prevented from generation. As noted above, a part of a pipe, both ends of which are airtightly secured to th outer pipe of a sheath heater, is radially expanded to form a projecting ring to reduce generation of a thermal stress, and this enables prevention of break of a weld bead due to a thermal stress.

摘要： PURPOSE:To constitute an igniter of a kerosene burner which can perform reliably ignition under a low temperature without necessitating a transformer and generating a noise, by controlling a current electrifying an ignition heater by connecting the ignition heater and a preheater with each other so that they become a series at the time of the ignition. CONSTITUTION:When a power source switch 11 is turned ON, relays 21, 22 are turned ON by a controller 12 and preheating is started. When an evaporation wall 3 is arrived at a temperature of about 200 deg.C, the relays 21, 22 are turned ON and OFF respectively by the controller 12, electrification to an ignition heater 20 is started, ventilation is made by a blower motor 17 by turning relays 13, 15 ON successively by the controller 12 and oil supply is started by a solenoid pump 18. In addition to the above, an air-fuel mixture formed by mixing kerosene evaporated by an evaporation wall 3 and air with each other is blown off from a flame hole by passing through a partition plate 6, a distributing plate 7 and flame hole plate 8 and ignition is performed by the ignition heater 20 which has been preheated in red. As impedance between a flame rod 10 and the flame hole plate 8 is declined when the titled igniter is ignited, detection of ignition is performed, and the relay 22 is made to turn OFF and forced ON of the relay 21 is released also by the controller 12.

摘要： PURPOSE:To minimize the temperature change of hot water even if the flow rate of hot water is changed abruptly, by controlling the temperature of hot water in combination of a proportional factor and an integration factor of the water temperatue at the outlet of a heat exchanger. CONSTITUTION:When the temperature of hot water detected by a sensor 12 disposed at the outlet of a heat exchanger 10 becomes higher than a set temperature, combustion is stopped once and then recommenced about 2-4sec later, and control on the temperature of hot water is recommenced by resetting the integration value of temperature deviation to zero. Providing that TW1 is a temperature signal supplied from a temperature detecting sensor 12 and TW0 is a set temperature signal, the temperature of hot water is controlled by controlling the combustion rate by applying a voltage E (E=EP+E1+E0) to a motor 1, where EP [EP=C1(TW0-TW1)] is a proportional item proportional to the deviation between TW0 and TW1, E1 [E1=C2(TW0-TW1)dt] is an integration item obtained by integrating the deviation, and E0 is a constant. In the above formulas, C1, C2 are also constants. Here, since the constant E0 has a function to increase the rising speed, it is enabled to reduce the temperature rise at the time when the supply rate of hot water is reduced abruptly and hence to supply hot water with small temperature change.
摘要翻译：目的：为了尽量减少热水的温度变化，即使热水的流量突然变化，通过将热水的温度与热交换器的出口处的比例因子和水温的积分因子结合起来，。构成：设置在热交换器10的出口处的传感器12检测到的热水温度高于设定温度时，停止一次燃烧，然后重新开始约2-4秒钟，并控制热水温度通过将温度偏差的积分值重置为零开始。提供TW1是从温度检测传感器12提供的温度信号，TW0是设定温度信号，通过对电流E施加电压E（E = EP + E1 + E0）来控制燃烧率来控制热水的温度电机1，其中EP [EP = C1（TW0-TW1）]是与TW0和TW1之间的偏差成比例的比例项，E1 [E1 = C2（TW0-TW1）dt]是通过积分偏差获得的积分项，而E0是常数。在上式中，C1，C2也是常数。这里，由于常数E0具有增加上升速度的功能，所以能够在热水供给速度急剧下降的同时降低温度上升，从而供给温度变化小的热水。
