摘要:
Known chimneys or chimney furnaces use flue gas flow units for heating buildings, said devices having displaceable or fixed obstacles for deflecting flue gas for generating flue gas turbulence. The invention relates to a device and method for transferring heat through a flue gas discharge pipe (28) in which (44, 45) pivotal guide plates (37) are inserted in the longitudinal direction of the pipe run, at which the flue gas flow (22) is more or less deflected in a sinuous line as a function of the pivot angle (24) of the guide plates (37) that can be adjusted during furnace operation. A fan (19) can increase the flue gas flow (22). An optional furnace heat exchanger (29) generates additional hot water as needed. The controller (5) activates the actuators for the fan (19), guide plate pivot angle setting (24), and at least one circulating pump (10 or 11) as a function of the prescribed controlled variables such as flue gas temperature, reservoir temperature, heat exchanger performance, or flue gas flow. Due to the improved combustion, the invention enables increasing the energy efficiency of the furnace system, reducing pollutant emissions and fuel consumption, and increasing operator comfort. The independent adjustability and activation of the media flow makes integration in other heating circuits easier. Water or solar carrier fluid can be used as a heat transfer fluid for storing heat.

An apparatus is provided for rotating heated air in a chamber (16) adapted for receiving a heat source (36). The apparatus has a gas inlet opening (24, 26, 30) and a gas outlet opening (32), wherein the gas inlet opening (24,26,30) and the heat source are located in a lower area (12, 20') of the chamber (16) and the gas outlet opening (32) is located in an upper region (14) of the chamber (16) so that, when a heat source is placed in the chamber (16), an ascending gas flow may be generated in the chamber (16). The chamber (16) tapers inwardly from bottom to the top and that the gas inlet opening (24, 26, 30) is formed so that inflowing gas flows therethrough in a directed manner along a directional vector into the lower area (12, 20') of the chamber (16) such that a substantial component of the direction vector projects along an inner wall of the chamber and follows an at least approximately circular path along the inner wall in a common rotational sense around the heat source and then is drawn upwardly by a draw of the ascending gas flow along an approximately spiral path and then though the gas outlet opening (32). A cylindrical liner (220) is rotatably displaceable about the central axis (A-A) of the apparatus and includes at least one blocking portion (222) which, when the liner is selectively rotated about the central axis, selectively blocks the air flow through an adjacent channel (24, 26, 30). Further, a candle assembly is provided having at least one wick, the candle assembly formed of at least two wax parts which interface together to allow selective juxtaposition of wax parts having desired color combinations, scents, and wax compositions. The parts, when fit together conform to in inner form of a receptacle, and are held together with the at least one wick in such receptacle. Optionally, at least one part has a recess into which the at least one wick may he held in place or positioned to facilitate accurate assembly.

摘要:
A burner (40) having a transition zone (46) to act as a buffer between the primary zone (42) and the secondary zones (48, 50). The transition zone (46) allows improved control of near-burner mixing and flame stability by providing limited recirculation regions between the primary zone (42) and the secondary zones (48, 50). These limited recirculation regions transport evolved NOx back towards an oxygen-lean pyrolysis zone near the burner exit (52) for reduction to molecular nitrogen, thus decreasing emissions and unburned fuel losses.

A flue insert (50) for insertion into a flue stack (12). The flue insert includes a sleeve (52) that is inserted into the stack so as to function as part of the stack. A vane (54) is disposed in the sleeve. One end of the vane is fixedly attached to the sleeve. The opposed end of the vane is adjustably attached to the sleeve so that after the insert is installed, the overall length of the vane can be selectively set.
摘要:
A draught limiting and injection device for supplying combustion air to a combustion appliance and discharging combustion gases of the combustion appliance to a discharge device arranged on the outside of a building. The draught limiting and injection device comprises an outer tube (14) for connection to the combustion appliance and the discharge device. The device further comprises an inner tube (20) for connection to the combustion appliance and functioning as injector (24). The inner tube opens into the outer tube, and a wall of the outer tube is provided with a first air supply opening (12) for supplying combustion air to the combustion appliance. The wall of the outer tube is further provided with a second air supply opening (32) for possibly supplying air to the discharge device to limit the draught.
