摘要:
An exhaust vent adapter is provided for use in a heating system having a plurality of heating units, which allows all heating units to discharge combustion gases through a single exhaust opening. The adapter comprises a body with a plurality of discrete chambers formed therein, each chamber communicating with a separate heating unit. The body of the adapter has a single exhaust opening formed therein, through which each chamber is independently connected to a separate exhaust vent pipe. The vent pipes leading from plurality of the chambers are concentrically arranged, and may be extended through a single opening in either the wall or ceiling of a building in which the heating units are installed. In a preferred embodiment, the body of the adapter has a single divider secured therein, which defines two chambers and segregates the combustion gases from a pair of heating units.

A power generation system has a power generation unit (1), a casing (2) accommodating the power generation unit (1), a ventilator (3) configured to ventilate the interior of the casing (2), and a first exhaust gas passage (4) configured to pass therethrough an exhaust gas from the ventilator (3) which is discharged out of the casing (2). The first exhaust gas passage (4) merges with a second exhaust gas passage (6) connected to a duct (11) open to outside air before the second exhaust gas passage (6) is connected to the duct (11), the second exhaust gas passage (6) being configured to pass a combustion exhaust gas from a combustion device (5) configured to generate heat to be supplied to a heat load.

The present invention relates to a control method of preventing backflow of exhaust gas of a multiboiler that is composed of a plurality of boilers connected in a line, each of which includes a wind pressure sensor measuring wind pressure of air flowing into a combustion chamber and a controller controlling the number of revolutions of a fan supplying air into the combustion chamber on the basis of the wind pressure measured by the wind pressure sensor, and in which any one of the controllers is set as a master controller and the other controllers are set as slave controllers and the master controller and the slave controllers are connected by a communication line to communicate with each other, and the control method includes: measuring wind pressures of air flowing into the combustion chambers using the wind pressure sensors in the controller of boilers that are in operation; and calculating the average wind pressure of the boilers that are in operation in response to information about the wind pressures measured by the controllers of the boilers that are in operation, using the master controller, determining the control amount of wind of the fans of boilers that are not in operation on the basis of the average wind pressure, and then operating the fan of the boilers that are not in operation on the basis of the determined results. According to the method, it is possible to provide a multi-boiler or a multi-water heater that does not generate additional cost for installing the dampers are not needed and does not substantially breakdown due even though it is used for a long period of time, thereby saving cost for maintenance.
摘要:
A fan assembly comprising two fans (4, 10) for supplying combustible gases to two burners (5, 9) respectively. The flow parts from the first and second burners are combined in a common manifold. Temperature censor (6, 11) detect the temperature of the gases passing through each fan, and the speed of a particular fan is increased if the temperature sensor detects reverse flow of combustion gases.

The invention relates to an arrangement (1) including two burners (10), which has a common exhaust gas guiding device (2) and a common supply device (3) for combustion air. A backflow barrier (4) blocks a flow of a gaseous medium in a flow direction and is arranged in the exhaust gas guiding device (2) or in the supply device (3). The backflow barrier (4) has an opening (40) and a movable element (41) which is movable between two positions. The opening (40) is open in case the movable element (41) is in one of the two positions and closed in case the movable element (41) is in another of the two positions.
摘要:
A collective air intake and exhaust chimney suitable for outdoor installation which avoids clogging by snow or frost, which comprises an inner flue (8), a heat insulating layer (12), an outer flue (13), an intake passage (10) between the outer flue and the heat insulating layer, and an exhaust passage inside the inner flue. The device has a double flue branch (3) suitable for connection, e.g., to each floor of a building, which is preferably similar in size and structure to the double flue (8, 12, 13) of the intake and exhaust chimney, and is adapted to be slidably fitted to the intake and exhaust pipe of a forced draft direct vent type heater, and is supported by a supporting member.
摘要:
The adjustable pipe fitting of the invention has double walls in accordance with Type B standards established by the American National Standards Institute and Underwriters Laboratories. In the preferred embodiment, the invention comprises a main conduit having three sections which are rotatably coupled together. A branch conduit is securely connected to the main conduit so that fluid communication exists between the branch and main conduits. The branch conduit also comprises three sections which are rotatably coupled together. The main conduit sections and the branch sections are coupled together at oblique angles relative to their respective longitudinal axes to provide a means for adjusting the fitting to accommodate connector pipes having various angles and orientations.
