TL;DR: The utility model relates to a gas heater with functions of primary water preheating and heat insulating during interruption period, which comprises a cold water inlet (1), an ignition controller (2), a hot water outlet (4), a pressure reducing valve (5), a water outlet pipe (6), a tap (10), water temperature inductor, a circulation water pump (7), a return pipe (8), and a double-pipe three-way connector (9) as discussed by the authors.
Abstract: The utility model relates to a gas heater with functions of primary water preheating and heat-insulating during interruption period, which comprises a cold water inlet (1), a cold water inlet pipe (2), an ignition controller (3), a hot water outlet (4), a pressure reducing valve (5), a water outlet pipe (6), a tap (10), a water temperature inductor, a circulation water pump (7), a water return pipe (8) and a double-pipe three-way connector (9). The utility model has the advantages that when the utility model is freshly opened or is opened again after the utility model is closed in the process of use, water temperature is effectively preheated so that the water discharged is hot water because the water temperature inductor and the circulation water pump respectively have an inner circulation system, and water resource is saved.

TL;DR: In this article, the authors presented a method for enriching a blast furnace gas with coal briquette preheaters and dedusters to increase the heat value of the gas and reduce the emission of carbon dioxide.
Abstract: A blast furnace gas enrichment apparatus and a method belong to the technical field of blast furnace gas. The apparatus comprise a feeder, a coal briquette preheater, a distributor, a heat exchanger, a gas-heating furnace, a gas bustle pipe, gas spray guns, a shunt, an ash tray, a gas enrichment furnace, a deduster, a gas storage tank, an oxygen pipeline and a gas outlet pipeline. Blast furnace gas is adopted as material, gas is adopted as energy, oxygen is adopted as oxidizer, and non-coking coal, nut coke and the like are adopted as reducers; after nitrogen is removed from the blast furnacegas and the blast furnace gas passes through a preheater and is enriched, the gas carries out heat exchange, and enters a gas heater, the gas heater utilizes the high-heat value gas to burn with oxygen to provide heat for the blast furnace gas, so that the temperature of the blast furnace gas reaches 800 DEG C to 900 DEG C, the blast furnace gas is blown into the furnace from around the furnace wall, coal briquettes are packed in the gas enrichment furnace, the main reduction task is fulfilled in the coal briquette-packed bed, and thereby high-heat value gas is produced. The invention has theadvantages that: the heat value of the blast furnace gas is increased, and the emission of carbon dioxide is reduced.

TL;DR: In this paper, a heat generator assembly with a hot element and a cold element is described, where the thermal coupling portion is provided with two lateral heat transfer surfaces (55a,55b) which are not parallel to the hot element.
Abstract: The heat generator assembly (25) has a heat generator (54) which is provided with a hot element (31) and a cold element (41) which are thermally coupled to each other and directed outwards in opposite directions. The thermal coupling portion is provided with two lateral heat transfer surfaces (55a,55b) which are not parallel to the hot element and cold element. An independent claim is included for gas heater.
