摘要： Energy and water are recovered from flue gases by cooling them to a temperature sufficiently below the acid dew point temperature by contact with an aqueous stream so as to recover the sensible heat and to reduce the water content of the flue gases by about 50%. The water by which the aqueous stream is enriched is subsequently flashed off to cool the stream back to its original temperature and the water vapor is then compressed to generate a higher temperature vapor stream which is condensed to recover the water and extract heat. The aqueous stream is continuously enriched with material such as calcium carbonate to control the pH sufficiently as to avoid substantial corrosion due to acidic gases removed from the flue gases and the aqueous stream is purged continuously or periodically to remove compounds such as chlorides, calcium sulphates, and fly ash solids picked up from the flue gases. The system may be operated in two stage fashion in which separate aqueous streams are employed to cool the flue gases in two serial stages.

摘要： This invention relates to the conservation of energy in a domestic gas water heater by utilizing the hot exhaust gases in a gas water heater for the preheating of the incoming unheated water into the water heater.The exhaust gases from a domestic gas water heater carry wasted heat and the present invention provides a mean to reclaim part of the wasted heat for the preheating of the incoming unheated water during hot water usage periods. During non hot water usage periods the heat in the exhaust gases is not reclaimed to prevent overheating of the water and also to prevent the formation of water deposit in the preheating assembly or heat reclaimer. During the non hot water usage periods the heat produced in the water heater is normally needed only to maintain the desired water temperature of the stored water in the water tank of the water heater.Due to the rapid heating or recovery rate, the present invention enables the use of a smaller water heater. The use of a smaller water heater reduces the normal heat loss from the stored hot water thereby further reduces energy consumption.
摘要翻译： 本发明涉及通过利用燃气热水器中的热废气来将进入的未加热水预热到热水器中的家用燃气热水器中的能量守恒。 来自家用燃气热水器的废气携带浪费热量，本发明提供了在热水使用期间预热未加热水的部分废热的方法。 在非热水使用期间，排气中的热量不被回收以防止水的过热，并且还防止在预热组件或热回收机中形成水分。 在非热水使用期间，通常仅需要在热水器中产生的热量来保持热水器的水箱中储存的水的期望水温。 由于快速加热或回收率，本发明能够使用较小的热水器。 使用较小的加热器减少了从储存的热水中的正常热损失，从而进一步降低了能量消耗。

摘要： An improved method of exchanging heat between combustion gases from combustion of fossil fuel with air and a fluid to be heated is obtained by initially introducing into the exhaust gases a volatile medium to be vaporized by said gases and subsequently condensing the vaporized medium by cooling the obtained mixture of combustion gases and vaporized medium to a temperature below the dew point. The cooling is performed by the fluid to be heated. The new method reduces the contents of polluting ingredients in the exhaust combustion gases and will keep the heat exchange structures clean.

摘要： A fan includes: an impeller including a main plate having a first plane, a plurality of first blades each formed the first plane, and a shroud formed integrally with the plurality of first blades; a fan case; a drive source; and a rotation shaft. The first blades each include a linearly protruding region that is linearly increased in height from an outer circumferential side to an inner circumferential side, and a curvedly protruding region that is curvedly increased in height from the outer circumferential side to the inner circumferential side, the height extending in a direction in which each first blade protrudes. The linearly protruding region is welded to the main plate. Accordingly, a highly durable fan can be implemented that allows sufficient durability to be maintained even under a high temperature environment or an acid environment.

摘要： A fluid heating apparatus may comprise a fluid pumping assembly configured to increase a pressure characteristic of the fluid between the fluid inlet and fluid outlet, and a heating assembly configured to heat the fluid between the fluid inlet and the fluid outlet. The heating assembly may define a first portion of a gas path such that exhaust gases from combustion in the heating assembly enter the gas path. The apparatus may also comprise a heat recovery assembly configured to recover heat from the exhaust gases and transfer recovered heat to fluid moving through the fluid path. The heat recovery assembly may define a second portion of the gas path in fluid communication with the first portion of the gas path. An exhaust gas movement device may be configured to pull exhaust gases through the first and second portions of the gas path to the gas movement device.
