Abstract: A plate type heat exchanger for liquid is provided to prevent liquid boiling due to the difference of heat capacities as two kinds of the liquid exchange heat with each other, thereby improving the lifespan and the safety of a system. A plate type heat exchanger for liquid includes path spaces for fluid to be heated and heating fluid. In order to prevent the boiling of the fluid to be heated while a system is stopped operating since the temperature of heating fluid is much higher than that of the fluid to be heated, the path spaces(A1-An) for the fluid to be heated are formed larger than those(B1-Bn) for the heating fluid so as to provide a heat capacity(the boiling point) of the fluid to be heated equally to or larger than that of the heating fluid.

Abstract: 본발명은배기가스재순환연소방식을질소산화물(NOx)을저감시키는이론을적용하는응축식소형가스보일러의구조및 연소방법에관한것으로, 보다상세하게는보일러에있어서가장중요한기술개발대상과제인공해저감과효율향상에관한사항으로서보일러의안정된연소상태를유지하면서연소과정에서발생하는환경오염물질인질소산화물(NOx)의배출을최소화하고, 연소배가스중의포함된수분의보유열량을적극회수하여보일러의열 효율을극대화하기위한가정용및 소형가스보일러의구조에관한것이다. 상기와같은목적으로기존의소형가스보일러에서전혀사용되지않던구조로서배기가스의재순환연소법을적용하기용이하도록무동력의이젝터를사용하여배가스일부를연소용공기의공급력에의해서함께흡입되어혼합되도록하며, 기존의가정용보일러에있어서효율향상을목적으로열교환전열면확대와응축열회수를위하여 2개의별도열교환기를직열로연결하여사용함에따른열교환기의보일러내부공간배치특성이좋지않고보일러제작이나쁜단점의보완과전열성능향상을위하여충분한응축열을회수할수 있을정도의전열면적을갖는 1개의열교환기로서기존의판형핀의형태를그대로사용하면서판형핀형태의격벽을핀 중간에설치하여 2패스방식으로전열면을분리시키는데착안하여연소가스의유동구조를 2패스방식의구조를갖게함으로서기존의응축형보일러에비해구조를단순화시키고, 배가스의공해물질배출량을줄이며, 열효율을증대시킨보일러구조를갖는다. 이와같은보일러의구조는가정용을포함하는기존의소형보일러에비해서질소산화물저감을위한높은공기비연소에따른효율저하를방지할수 있으며, 보일러의연소량즉 부하의변화에따른응축수발생위치의변화와연소가스의급격한온도저하에의한굴뚝에서의응축현상으로인한폐해를완화시킬수 있고, 격벽의전열핀화에따른격벽의과열방지, 예혼합연소방법에배가스재순환법의적용에따른안정성유지및 수관군연소의적용에따른화실확보에따른보일러크기의감소등의많은장점을갖는다. 배기가스일부를재순환시켜서공기및 연료가스와함께모두미리혼합하여연소기에공급하여연소시키는방법은재순환시키지않는보일러의경우에비하여연소반응이지연됨으로서화염의온도를일차낮추어서열 NOx의발생을근본적으로억제할수 있는데, 일반적으로확산화염이나세미분젠화염과같이역화나가연한계밖의혼합기에대해서는안전성유지가비교적용이하나이와같이예혼합연소에서는배가스의온도가높으면자체발화하여연소기내부에서연소될수 있기때문에응축형보일러와같이배가스온도가낮은경우에만이 배가스재순환법을예혼합연소에적용하여연소중에발생을억제할수 있으며, 동시에화염중에핀붙이수관을배치하여화염온도를더욱낮춤으로서열 NOx 발생을최소화한다. 동시에보일러의핀붙이수관전열면을 2 패스방식으로확장배치하여배기가스의응축잠열을회수함으로써열효율을극대화할수 있을뿐만아니라응축수의배출이용이한구조이다.

Abstract: PURPOSE: A condensate neutralizer is provided to spray boiler pipe water or blow-down water having high alkalinity to a heat transfer face to prevent the heat transfer face of a condensing heat exchanger from corrosion. CONSTITUTION: A flow limit valve(12) is mounted on a blow-down pipe. A T tube is mounted in front of the limit valve to supply a part of blow-down water to a sprayer(14) through a filter(18) via an electronic valve(11) for pH balancing. An electronic valve(9) for blow-down adopts automatic mode instead of manual one. Thereby, inner pressure of a boiler is transferred to blow-down water by the limit valve to supply the blow-down water to the sprayer in any case. The spraying amount of blow-down water is controlled depending on the opening of the electronic valve for pH balancing. High-temperature high-pressure water in a boiler pipe is cooled through a blow-down water heat exchanger(10) to prevent sudden pressure falling. To spray the boiler pipe water or the blow-down water having regular alkalinity to a spraying nozzle or a pipe, the sprayer adopts a spraying orifice. The boiler pipe water or the blow-down water is sprayed regularly to the heat transfer face of a condensing heat exchanger. Therefore, a condensate having high acidity is washed out and the heat exchanger is prevented from corrosion.
Abstract translation: 目的：提供一种冷凝中和器，将锅炉管道水或碱度高的吹扫水喷射到传热面上，以防止冷凝热交换器的传热面受到腐蚀。 构成：流量限制阀（12）安装在吹风管上。 T型管安装在限制阀的前方，通过用于pH平衡的电子阀（11）通过过滤器（18）将一部分吹扫水供应给喷雾器（14）。 用于吹扫的电子阀（9）采用自动模式而不是手动模式。 因此，在任何情况下，通过限制阀将锅炉的内部压力转移到排放水中以将喷射水供应到喷雾器。 根据用于pH平衡的电子阀的开度来控制吹扫水的喷射量。 锅炉管中的高温高压水通过吹扫水热交换器（10）冷却，以防止突然的压力下降。 为了将锅炉管水或具有规则碱度的吹扫水喷洒到喷嘴或管道上，喷雾器采用喷嘴。 锅炉管水或排污水定期喷射到冷凝热交换器的传热面上。 因此，具有高酸度的冷凝物被洗出并且防止热交换器腐蚀。
