摘要： PURPOSE:To realize a short length flame by a method wherein both sides of a secondary air passage body have flame openings and a secondary air injection plate is arranged downstream of the flame openings, which are inclined towad the downstrream of the passage body. CONSTITUTION:When the combustion is performed, a combustion air supplied by a fan 1 is divided into a primary air and three kinds of secondary air by a divider plate 2 and then supplied to the main body of the burner 3. In turn, the fuel is supplied by the fuel pipe 5 and injected from the nozzle 6, mixed with the primary air while it is flowed in the mixture passage 17, thereafter injected into the combustion chamber 21 from the flame openings 9... via clearance 12 and combustioned. At this time, since the flame opening plate 10 is inclined toward the downstream side, a flame diversed in the combustion chamber 21 is formed. In turn, the secondary air is divided and supplied into a pair of secondary air chambers 13 and the passage 8 and supplied as an opposing injection flow inclined toward the flame by the injection plate 15 inclined toward the downstream of the chamber.

摘要： PURPOSE:To prevent occurrence of flash back by such a structure that a fan is made to be small by providing flame holes and air holes in an angled convex- concave pattern and shortening the length between the air holes opposing to each other and mixture passages and air passages are arranged alternately in a unit integrally molded of a material of high conductivity. CONSTITUTION:A combustion part is constituted by an plurality of units each having an angled convex-concave pattern. The air holes are formed on the both sides of the convex part of the pattern, with the length between the opposing secondary air holes 10 being shortened in the length l, and the flame holes 9 are arranged in the concave surfaces between the convex parts. The mixture passages are provided, each having a mixture gas passage 6, a mixture gas box 7 and a flame hole 9, and the air passages are also provided, each having a secondary air supply port 13, a secondary air supply pipe 5, and an air hole 10. Shortly before reaching the flame holes and air holes 10, both passages are constituted by the unit integrally molded of the material of a high conductivity, with the length few times as long as the depth of the flame hole. By this, the fan can be made to be as small as possible and the occurrence of flash backs can be prevented.

摘要： PURPOSE:To contrive reduction of pressure loss for secondary air supply, by a method wherein a high load combustor part is constituted by casting a heat exchanger pipe in aluminum material whose thermal conductivity is favorable and holding a flame hole, a secondary air jet and fin part for heat exchange between heat exchanger pipes. CONSTITUTION:As mixed gas reacts at a high temperature within a hatched area, a temperature of a flame hole 10 and a secondary air hole 11 becomes high, but if a device is a water boiler, the temperature can be reduced to a low temperature 50-100 deg.C as the temperature of the flame hole 10 and the secondary air hole 11 is close upon that of a material to be heated flowing within a heat exchanger pipe 9 as they are constituted of aluminum material having favorable thermal conductivity and the heat exchanger pipe 9 is built-in the vicinity of the flame hole 10 and the secondry air hole 11 in a body. With this, a fan can be miniaturized as the temperature is lowered and a pressure loss is reduced.

摘要： PURPOSE:To contrive the enlargement in high-load combustion and TDR (Turn Down Ratio) range in a combustion device for a heating system in which forced air supply is made through a fan, by a mechanism where in the combustion chamber walls are composed of fins and water tubes, with secondary air outlets being provided in stages in a part of the combustion chamber walls. CONSTITUTION:The amount of secondary air to be supplied via the No.1 and No.2 passages is properly adjusted through the adjustable dampers 6 and 7 respectively to be fed into the secondary air chambers 8 and 9. The secondary air then flows out of the secondary air outlets 10 and 11 to be directed uniformly at the flame forming in the combustion chamber 15. The secondary air jet stream sends the flame spreading all over the combustion chamber 15 so that the flame undergoes heat exchange at the heat exchanger 17 which is of one-piece construction with fin pipes to be let out of the exhaust port 18. In this way, the supply of secondary air enables large-capacity, high-load combustion, helping extend TDR control range. Besides, the combustion chamber walls designed to serve as heat exchanger help prevent rise in temperature of the secondary air chamber and keep secondary air from being heated excessively. This enables miniaturization of the burning system employing a small-size fan.

摘要： PURPOSE:To enable a quick fire transfer into a shelter at ignition in the combustion safety device having a combustion sensor for a stove gas burner and the like by providing a fire transfer space within the shelter in which the sensor is arranged and opposed to a flame hole surface of the burner. CONSTITUTION:The gas burner 1 has the shelter 4 for arranging the sensor 2 made of zirconium oxide and the like and detecting an oxygen concentration difference occurring in the vicinity of the flame hole surface in a position opposite to the flame hole surface by means of a container 3. In this case, the shelter 4 is arranged to define a space near the falme hole surface of the burner 1 so that at the burner ignition, the fire can be transferred quickly into the shelter 4. Thus the sensor 2 surrounded by the shelter 4 can prevent any misoperation and detect any incomplate combustion of the burner 1.

摘要： PURPOSE:To accomplish high-load, high primary combustion with short flame, by drawing primary air through combined use of the suction effect exerted by the injection pressure of gas and that exerted by the suction pressure of a fan. CONSTITUTION:Since the air volume of a fan 9 is controlled by a combustion detecting element 21 consisting of a frame rod and others such that gas is combusted at a constant air-fuel ratio, primary air is drawn by the ejector effect exerted by the injection pressure of gas ejected from a gas nozzle 22 and also by the suction pressure of a fan 9. Thus, it is enabled to increase the amount of primary air drawn into the apparatus and therefore to accomplish high-load, high primary combustion of gas.
