摘要： The embodiments of the present application disclose a combustion control system of a gas water heater or wall-hanging boiler, and a control method thereof. The system comprises: a flue gas channel consisted of a combustor, a heat exchanger and a stepless speed regulating fan and a smoke tube, which are connected sequentially; a control unit connected to a signal input end of the stepless speed regulating fan; a wind pressure sensor assembly that detects a pressure signal upstream of an impeller of the stepless speed regulating fan, a signal output end of the wind pressure sensor assembly being connected to the control unit; the control unit comprising a storage for storing a correspondence relationship between the pressure signal upstream of the stepless speed regulating fan and a thermal load of the combustor, and a controller that controls operation of the stepless speed regulating fan according to the correspondence relationship. The present application further regulates the rotational speed of the stepless speed regulating fan by detecting the pressure signal upstream of the impeller of the stepless speed regulating fan, thereby achieving a better wind-resistant performance of the present application.

摘要： A device, system and method for heating fluid (air) in a flue to create a draw prior to combusting a fuel in a combustion device. The device, system and method includes a housing that may be integrated about the flue. The housing may include a heat exchanger that itself may include a heating source that may be in thermal communication with the flue and a temperature differentiation driver. The heat exchanger may operate to transfer heat energy from the heating source to a fluid constrained to a path created by the flue. The result is a pressure differential created within the flue to help draw the fluid out of the combustion device. The heat exchanger may be configured such that it may cause heat transfer to the heavier, more dense fluid contained within the ventilation system prior to combusting fuel in a combustion device, thereby causing the fluid to be relatively less dense thus creating a draw.

摘要： A flue tuning and emissions saving system is disclosed. The device or system includes an inlet duct (20) having an inlet cross-sectional area and an outlet duct (18) having an outlet cross-sectional area that is the same as the inlet cross-sectional area. An outer duct (16) that is of an outer duct cross-sectional area is sealingly connected to the inlet duct (20) and the outlet duct (18), while separating the inlet duct (20) and the outlet duct (18). At least one disc (12) that is positioned at a specified distance S between the inlet duct (20) and at the same S to the outlet duct (18) and centered in the outer duct, the disk (12) includes a specified disc area so that flow of an exhaust gas entering the system through the inlet duct (20) will be diverted by the disc (12) into the outer duct (16) before the flow continues to the outlet duct (18) without encountering a restriction in flow cross-sectional area. When two or more discs are used, an annular fin (22) that extends from the outer duct to create a passage of the inlet duct (20) diameter that separates the discs.

摘要： A plastic chimney cap is molded in one-piece from either a thermoset or a thermoplastic resin. The chimney cap has a wall extending continuously around a closed-circuit. The wall interior surface defines an interior space. A plurality of vent holes through the wall communicates with the interior space to vent combustion gases. A roof is attached to the upper edge of the wall. A flange is disposed outside the lower edge of the wall and has a perimeter extending completely around the wall. A shoulder connects the flange with the wall. Thickened reinforced regions with threaded holes and mounting screws are spaced apart around the flange perimeter for fastening the chimney cap to the flue. The interior surfaces can be coated with a metallized coating for heat resistance.

摘要： A duct system contains a narrow, liquid tight conduit filled with cold water which can be used to prevent fires in the ducts of chimneys, high rise buildings, restaurants and the like. If a fire starts in a duct, the wall of the duct heats up very slowly because of its proximity to the thin walled conduit containing the cold water (which gets warmer as the fire builds momentum). If the fire persists and the heat of the outer wall rises to a designated temperature (e.g. 200 degrees Fahrenheit), a valve opens and the heated water (the originally cold water) is flushed out and fresh cold water is brought in, further impeding the fire's progress. The fire will likely burn itself out without ever igniting any combustibles outside the duct walls. The flushed out water can be sprayed onto the roof of the building to prevent any burning fly ash from starting a fire on the roof.
摘要翻译： 管道系统包含一个填充有冷水的狭窄的液密导管，可用于防止烟囱，高层建筑物，餐厅等的管道中的火灾。 如果火焰从管道中开始，则由于其靠近含有冷水的薄壁管道（随着火势增加而变暖），管道的壁面加热非常缓慢。 如果火持续存在，外壁的热量上升到指定的温度（如华氏200度），阀门打开，加热的水（原来的冷水）被冲洗掉，并引入新鲜的冷水，进一步阻碍了 火的进步。 火灾可能会燃烧，而不会点燃管壁外的任何可燃物。 冲洗出的水可喷洒在建筑物的屋顶上，以防止任何燃烧的飞灰在屋顶上起火。
