摘要： The present disclosure relates to a boiler for making hot water and room heating water available simultaneously, which is capable of enabling a user to use hot water and room heating simultaneously. According to the present disclosure, a thermal loss of room heating water may be minimized because the room heating water is independently supplied to a room heating pipe and returned regardless of the use of hot water, and the hot water with a high temperature may be consistently supplied because the hot water is independently supplied to a hot water pipe and returned regardless of the use of the room heating water. In addition, the boiler may serve as both a hot-water heat exchanger and a distributor (low loss header).

摘要： A method and an arrangement for recovering heat from flue gas of a boiler (10). The method comprises passing the flue gas (G) of the boiler though a flue gas cooling unit (1), cooling the flue gas (G) by transferring heat from the flue gas (G) into a circulation (3) of a flue gas cooling liquid (CL), transferring heat energy of said flue gas cooling liquid (CL) into a heat pump (2), and arranging the heat pump (2) for receiving heat energy also from a circulation arrangement (8) of a district cooling system. The heat pump (2) is coupled to a circulation arrangement (6) of a district heating system, wherein the method further comprises transferring in the heat pump (2) heat energy (H) received from said cooling liquid (CL) and from said circulation arrangement (8) of district cooling system into said circulation arrangement (6) of district heating system, for lowering the temperature of said flue gas cooling liquid (CL) and cooling fluid of said district cooling system, and raising the temperature of heating fluid of said district heating system.

摘要： Disclosed is a water supply system that conditionally fills with heated water. The water supply system has a water tank configured to store and supply heated water, a heater configured to heat water in the water tank, and a sensor configured to sense a temperature of the water in the water tank. In accordance with an embodiment of the disclosure, the water supply system has a water supply unit configured to selectively supply heated water or unheated water to the water tank based on the temperature that has been sensed. In some implementations, this is performed to reduce use of the heated water, which may result in energy savings.

摘要： Liquefied natural gas (LNG) boil off gas (BOG) and/or end flash gas (EFG) can be used to recondense refrigerant vent gas. For example, a method can include: passing LNG BOG through a first condensing heat exchanger and/or passing an EFG from liquefaction system through a second condensing heat exchanger; and condensing the refrigerant vent gas in the first and/or second condensing heat exchangers, wherein (when using the first condensing heat exchanger) the LNG BOG is the coolant in the first condensing heat exchanger and (when using the second condensing heat exchanger) the EFG is the coolant in the second condensing heat exchanger, and wherein (when using both condensing heat exchangers) the first and second condensing heat exchangers are in parallel and not in series.

摘要： A latent heat recovery heat exchanger includes a heat exchange portion and a case. The heat exchange portion includes a plurality of heat transfer plates layered on one another. The case accommodates the plurality of heat transfer plates of the heat exchange portion. The heat exchange portion includes a front plate portion provided as an outermost layer of the heat exchange portion. The front plate portion of the heat exchange portion forms a part of the case.

摘要： A forced convection fin tube condensing heat exchanger for supplying heat includes a shell, burner and fin tubes bundle. The burner is at the top of the shell, circular fin tubes bundle installed around the burner tightly, circularly and coaxially. The flue channel which is formed by the shell and a row of fin tubes bundle is below the burner. The flue flows along the flue channel to flue outlet. There are front and rear water manifolds at the two ends of the fin tubes. Water baffles inside the rear water manifold divide the rear water manifold into water inlet and outlet areas. The water enters the small portion of circular fin tubes bundle from water inlet area, through the front water manifold, back to the water outlet area via the main portion of the circular fin tubes bundle. The use of bent fin tube to improves efficiency.

摘要： A water heater has a primary heat exchanger having a first heat transfer tube, a secondary heat exchanger having a second heat transfer tube connected with the first heat transfer tube and being located higher than the first heat transfer tube, and an outflow path connected to an outflow-side end portion of the first heat transfer tube. The outflow path has an offset flow path portion including a rising portion which rises upward or obliquely upward from a connecting portion of the outflow path and the outflow-side end portion of the first heat transfer tube or from the vicinity of the connecting portion, the offset flow path portion being offset at a position higher than the outflow-side end portion. When hot water supply is temporally stopped, the water at high temperature in the first heat transfer tube flows into the offset flow path portion, thereby inhibiting such a disadvantage that water having a lower temperature than a target temperature is supplied because of a natural convection at the time of restarting hot water supply.
