摘要： PURPOSE:To reduce NOx, and to utilize radiant heat effectively by forming a combustion plate by a porous sinter and surrounding a flame forming section by a cylindrical reflecting plate, an upper section thereof is opened, while mounting the second reflecting plate to an upper section. CONSTITUTION:Hot-air blowoff ports 1A are shaped in front of the upper section of a box body 1 and suction holes 1B to the back of the upper section while the reflecting plate 3 which surrounds the combustion plate 9 consisting of the porous sinter of a combustion apparatus A is mounted. The reflecting plate 3 is the first hollow cylindrical plate, an inner surface thereof is specular, and the upper end section is opened. The second reflecting plate 4 is set up to an upper section in the box body 1 opposite to the upper opening section of the first reflecting plate 3. The surface at the side opposite to the flame forming section is also made specular in the same manner as the first reflecting plate 3 in the reflecting plate 4. Accordingly, radiant heat can be utilized efficiently.

摘要： PURPOSE:To realize a stable detection of the oxygen content in the room air with a small erroneous action by inactivating the oxygen content detecting element for a predetermined period of time after starting the combustion and providing an converting element making the operation of the above oxygen content detecting element effective after lapse of a predetermined period of time. CONSTITUTION:A signal A of an ionic current of flame is compared with a basic voltage D in a voltage comparator 3. The result of the comparison is supplied to a signal F. Counting is started after a reset signal E is released by a timer 2 for setting a predetermined time (about 15min), and when the reset signal E is in a nonreleasing state and during the counting operation, a signal meaning nonoxygen-starvation is supplied to a signal B, and after the counting a signal meaning oxygen starvation is produced. If either one or both of the signal F and the signal B show an oxygen starvation state, the signal C becomes nonoxygen starvation. When both signal F and signal B become an oxygen starved state, the signal E is released simultaneously with the combustion starting.

摘要： PURPOSE:To make uniform and stabilize the temperature of hot air by providing a secondary air forced supply port leading to an air supply path at the side plate of a combustion cylinder. CONSTITUTION:A secondary air forced supply port 7 leading to an air supply path 4 is provided in a side plate portion 2a of a combustion cylinder in the neighborhood of a combustor 1, whereby permitting the supply of secondary air for combustion to be performed exactly and stably. Thus, the secondary combustion reaction is accelerated, the length of secondary flame F2 is shortened, and space above the secondary flame F2 in the combustion cylinder 2 is increased, and hot air of uniform and stabilized temperature can be obtained. In addition, no eruption of the secondary flame F2 to the blow-off port 5 occurs and, therefore, damage to human body by burns can be prevented.

摘要： PURPOSE:To prevent an erroneous detection, by a method wherein a head and a vaporizing cylinder are coupled together through the medium of a conductor. CONSTITUTION:A conductor 6, through which the inside of a head 3 makes an electrical connection to the inside of a vaporizing cylinder 1, is provided. As a result, with the flame detecting rod 4 contacting of a flame F when burning, a flame current flows in a circuit, formed with the head 3, the conductor 6, the vaporizing cylinder 1, and a flame detecting rod 4, and firing and extinguishing of firing can be detected. Additionally, the flame can be detected correctly without the increase in an electric resistance even if a flame port part 3a in the head 3 is oxidated or corrected due to the combustion.

摘要： PURPOSE:To enable automatic regulation of a combustion amount, by a method wherein an air amount controlling system is controlled by means of an indoor temperature sensor. CONSTITUTION:A combustor 3 is preheated by a heater 3c, and air is flowed into a blast path 2 by means of a blower 1. Simultaneously, pressure is applied to a constant oil level vessel 6 through a pressurizing pipe 9, and a liquid fuel 5 is pushed out to vaporizing chamber 3a through a feed port 8 for combustion. During said process, a path 10a is in a condition to be fully opened, and an air amount also increases. Thus, a fuel is also increased in a supply amount to increase a combustion amount, and a rapid heating become feasible. When an indoor temperature rises, temperature, detected by means of an indoor temperature sensor 12, is compared with a given temperature in a control circuit 13, and when it exceeds a set temperature, an electromagnetic valve 11 closes a part of the path 10a. As a result, an air amount, passing through the path 2, decreases, and the liquid fuel 5, pushed out into the vaporizing chamber 3a, also reduces. Because the combustion amount decreases, an indoor heating is suppressed at a lowered level.

摘要： PURPOSE:To devise to keep the balance of air-fuel ratio to correspond to any condition by providing a fuel supply port and a bypass pipe arranged with a manual valve to conduct a part of air to the outside in a forced draft passage. CONSTITUTION:A forced draft device 3 is operated as soon as an adjusting valve 4 is opened. When a fixed amount of air is supplied to an air supply pipe 1, kerosene is sucked out from a fixed level oil tank 5 since a supply prot 12 of a fuel supply pipe 10 is arranged near the throat part of a nozzle 2. As a part of the air can be discharged to the outside through a bypass passage 22 by operating a manual valve 23 properly, the sucking amount of kerosene can be adjusted by adjusting the discharge air. The sucked kerosene is atomized and dashed to an evaporating face 15 to be heated and evaporated, and thus the pre-mixture of molecular fuel and air is fed to a combustion port 19 for combustion.
