A hot beverage brewing apparatus. A pressurized hot liquid delivery system provides liquid under pressure within a range of acceptable brewing temperatures without any mechanical pump. Water is apportioned into sealable tank volumes, one of which is heated to boil the liquid and produce steam under pressure. The pressurized steam displaces the liquid from the tank volumes in proportion and at a temperature that is within the acceptable brewing range. The hot liquid under pressure is directed to a capsule receiving station to infuse a material in a capsule. The capsule dispenses the brewed beverage without contacting the brewing apparatus.

The device and the method for forming steam are used for household appliance. Principle: water enters into the heated spiral tube chamber through the inner end of the spiral tube chamber; water contacts the side wall of the spiral tube chamber, and is vaporized, then diffused along the spiral tube chamber; part of the water droplets diffuses with vapor, and contacts the side wall of the spiral tube chamber gradually, then is vaporized; vapor is obtained from the outer end of the spiral tube chamber. In one word, the invention provides a method to obtain “dry” steam which doesn't contain water. It is more efficient than other facilities.

A method for operating a syngas cooler is provided. The method includes channeling a flow of syngas into an annular cooling chamber having a longitudinal axis, injecting a cooling fluid into a manifold such that the cooling fluid is channeled substantially circumferentially about the annular cooling chamber, and discharging the cooling fluid from the manifold such that the cooling fluid contacts a surface of the cooling chamber at a predetermined angle relative to the axis of the cooling chamber.

A necessary size and number of modules each obtained by housing a member including heat exchanger tube panels each comprising a heat exchanger tube bundle and headers for the heat exchanger tube bundle, an upper casing of an exhaust heat recovery boiler (HRSG), provided above the heat exchanger tube panels, heat insulators, and heat exchanger tube panel support beams provided on the upper surface of the upper casing into a transportation frame, are prepared according to design specifications of the HRSG, and side casings and a bottom casing except for the ceiling part casing are constructed in advance at a construction site of the HRSG, and the modules are suspended from above between adjacent support beams of the ceiling part to dispose the heat exchanger tube panel support beams of the modules at the set heights of the ceiling part support beams, and the support beams and the ceiling part support beams are connected and fixed via connecting steel plates, whereby the respective modules are transported to the HRSG construction site and can be easily constructed.

A method for generating steam from a feedwater inlet stream including impurities is disclosed. The method involves receiving the feedwater inlet stream at an inlet of a steam generator and causing the feedwater stream to flow through a tubing circuit to an outlet of the tubing circuit, the tubing circuit having a substantially un-rifled bore defined by a metal wall. The method also involves delivering a heat flux to the feedwater stream through the metal wall of the tubing circuit to generate steam by causing evaporation of feedwater within the tubing circuit, and controlling at least one of a flow rate of the feedwater stream and the heat flux to cause generation of an outlet stream at the outlet includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass. The steam portion provides sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature.

A method and device for forming steam with high pressure and a cleaner or iron comprising the device are provided.

A liquor gun holder for a recovery furnace includes a rail assembly, a carriage assembly moveably mounted onto the rail assembly such that the carriage assembly is moveable longitudinally along the rail assembly, a pivot pin supported by a bearing and extending laterally from the carriage assembly, and a cleaning assembly pivotally mounted onto the pivot pin such that the cleaning assembly is rotatable about a horizontal axis extending longitudinally through the pivot pin and is positioned laterally from the carriage assembly and the rail assembly, the cleaning assembly including a clamp adapted to secure a liquor gun thereon such that the liquor gun is rotatable with the cleaning assembly and is positioned laterally from the carriage assembly.

A combination space and hot water heater is comprised of an inner tank having an outer casing spaced therebout with insulation being interposed between the casing and the inner tank. The inner tank has a glass-lined inner surface and a heater is provided within the inner tank for heating a same volume of water within the inner tank. An anode is provided within the inner tank. A closed water circulating circuit is connected to the inner tank for circulating hot water from the tank through heat exchange means connected in the closed water circulating circuit. Preferably, but not exclusively, the heat exchange devices are radiators. The inner tank contains a predetermined same volume of recirculating water wherein minimal deposits are accumulated in the inner tank by not admitting fresh water thereby substantially preventing the build-up of deposits on heat exchange elements within the tank and the formation of harmful bacteria in radiators and corrosion and further wherein a high constant efficiency is achieved and the life expectancy of the hot water heater is substantially prolonged. At least one heat exchange coil is disposed in the inner tank and immersed in the water contained therein. The heat exchange coil is connected at one end to an outlet coupling to which a domestic hot water line is connected. An opposed end of the heat exchange coil is connected to an inlet coupling. The inlet coupling is connected to a pressurized water supply.

This invention concerns a heat-resistant assembly having a heat-resistant block conformed to the contours of boiler tubes and the surface of their connecting rib. The heat-resistant assembly has an arm which protrudes from the surface of the rib toward the heat-resistant block and which has a catch on the end. The block has an indentation in which the catch on the arm engages. The block can be hung on or removed from the tube assembly by means of the arms and indentations. The heat-resistant assembly is further distinguished by the fact that a space is created between the end of the arm and the indentation of the block. A fusible substance, which will melt when the temperature of the arm exceeds a given value, is placed in the space. The heat-resistant assembly is further distinguished by the fact that an indentation is formed in the block in which a heat-resistant sleeve is adhered to engage the arm. This arrangement makes it possible to manufacture the heat-resistant block using press molding.

The invention provides a damping steam boiler. The damping steam boiler comprises an upper boiler barrel, a lower boiler barrel, rising pipes and falling pipes, wherein the rising pipes and the falling pipes are connected between the upper boiler barrel and the lower boiler barrel. The rising pipes are internally provided with flow stabilizers, and the multiple flow stabilizers are arranged in the same rising pipe; and the space between every two adjacent flow stabilizers is constantly reduced in the fluid flowing direction of the rising pipes. According to the damping steam boiler, through gap changing of the flow stabilizers, when steam-liquid two phase flowing exists in the rising pipes, heat transmission is reinforced; and meanwhile, vibration of the rising pipes is weakened, and the noise level is reduced.

For inclusion on the line between the liquid wash supply and the discharge jets of a vehicle windshield liquid wash pumping system, a liquid wash heater secured on an engine manifold or exhaust pipe, comprising a housing with a thin-walled, relatively small diameter, non-linear liquid wash tube contained therein.

A low thermal expansion Ni-base superalloy contains, by weight % (hereinafter the same as long as not particularly defined) C: 0.15% or less; Si: 1% or less; Mn: 1% or less; Cr: 5 to 20%; at least one of Mo, W and Re of Mo+½(W+Re) of 17 (exclusive) to 25%; Al: 0.2 to 2%; Ti: 0.5 to 4.5%; Fe of 10% or less; at least one of B: 0.02% and Zr: 0.2% or less; a remainder of Ni and inevitable impurities; wherein the atomic % of Al+Ti is 2.5 to 7.0.
