本烟气冷凝式燃气热水器的结构采用烟气导流型。冷凝热交换器的材料为不锈钢。The structure of the flue gas condensing gas water heater adopts the flue gas diversion type. The material of the condensing heat exchanger is stainless steel.
工作原理是：The working principle is:
燃烧室在热水器的下部，高温烟气从燃烧室流入显热热交换器(为生活用水)，显热热交换器吸收大部分热量后，在显热热交换器的出口，烟气温度约降至200-250℃；低温烟气经过烟气导流板再经第二间隙流至冷凝热交换器，向上流动的烟气与冷凝热交换器中的换热管(管中为未经过热交换的冷水)发生热交换，烟气温度降到露点温度，再通过第一间隙、导流器由烟道排出，同时冷水是从冷凝热交换器进入后再流入显热热交换器的，这样冷凝热交换器内的冷水得到热交换后再流入显热热交换器，可使热水器的热效率提高12％左右；又在冷凝热交换器内，冷凝液积聚在底部，最后从冷凝液导管流出，经过中和处理后再排入污水排放系统。冷凝热交换器中的冷凝水管组采用不锈钢波纹管，结构无吸热片，不易结碳，且不锈钢耐酸腐蚀很强。The combustion chamber is at the lower part of the water heater. The high-temperature flue gas flows from the combustion chamber into the sensible heat exchanger (for domestic water). After the sensible heat exchanger absorbs most of the heat, the temperature of the flue gas drops by about to 200-250°C; the low-temperature flue gas passes through the flue gas guide plate and then flows to the condensation heat exchanger through the second gap, and the upward flowing flue gas and the heat exchange tube in the condensation heat exchanger (the tubes are not heat-exchanged The cold water) undergoes heat exchange, the temperature of the flue gas drops to the dew point temperature, and then it is discharged from the flue through the first gap and the deflector. At the same time, the cold water enters from the condensing heat exchanger and then flows into the sensible heat exchanger. The cold water in the heat exchanger flows into the sensible heat exchanger after heat exchange, which can increase the thermal efficiency of the water heater by about 12%. After neutralization treatment, it is discharged into the sewage discharge system. The condensed water tube group in the condensing heat exchanger is made of stainless steel bellows, the structure has no heat-absorbing fins, it is not easy to carbonize, and the stainless steel is highly acid-resistant and corrosion-resistant.
