Performance Characteristics：
1. High efficiency and energy saving
Utilizing highly efficient Korean vacuum hot-water boiler technology, the boiler operates under vacuum conditions with low heating point. The steam heating (condensing for heating) effectively improves heat efficiency with good ability to exchange heat and tri-circulation design. The rear smoke path installs surplus heat recycle equipment to increase resource usage rate. The heat usage rate is as high as 91%.
2. The unit operates under pressure with safety
The unit operates in vacuum. The heat media is under vacuum condition with no danger of expansion or explosion. The boiler also stores constant heat-media water without danger to burn out. There are many self-protection installations with un-matchable safety features by other boilers.
3. No Rusting, no accumulation to prolong usage life
The heat exchange machines uses stainless steel material for the heat-media to operate under closed space. Under high temperature, there is no rusting, no furring to prolong the life of the boiler, almost twice as the normal boilers, making it almost 20 years.
4. Abundant models, various usage for one machine
There are vertical, horizontal, oil-burning, water-pipe, and gas-pipe various models for the users to choose. Heat exchange machine and collection machine are separate. Warm water and clean hot water bearing can be alternated based on needs to satisfy different needs from the customers for guarantee of the cleanness and stability of hot water.
5. Small volume, easy for installation
Module design, high quality heat exchange components, and the unit bulk is small. All these made transportation and installation easy. In a small space, many units can be used together.
6. Extraordinary Environmental friendly functions
Utilizing high functional burner with circulating flame structure design to completely burn the fuel. Various environmental indicators reach the national standards of travel zone exhaustion.
7. Elimination of complicated inspection procedures
The unit operates under vacuum conditions, eliminating the reporting for inspection for pressured vessels. There is no annual inspection needed, and no special permit is need for operation.
8. Intelligent Control
Touch-screen display, simulated buttons, with Chinese and pictured display operating conditions, online operating manual, automatic failure detection, and automatic operation and manual operation are both available. True dialogue between people and machine is possible.
工作原理(Work Principles)
真空熱水鍋爐是利用熱媒水的相變進(jìn)行熱交換的，燃料燃燒釋放出的熱量被熱媒水吸收，當(dāng)溫度上升至某真空度狀態(tài)下的飽和溫度時(shí)，蒸發(fā)成飽和蒸汽，完成次相變過程；飽和蒸汽容重較小，在真空室迅速上升，并在真空室與冷凝交換器進(jìn)行熱交換，蒸汽被冷凝成水，釋放出凝結(jié)潛熱，完成第二次相變過程。凝結(jié)水流進(jìn)蒸發(fā)室繼續(xù)吸熱，完成相變循環(huán)。
真空熱水鍋爐的下部結(jié)構(gòu)由燃燒室和傳熱管束組成；上部為真空室，其中插入了U型管熱交換器；真空室外接抽氣單元，使真空室保持穩(wěn)定的真空度，并將真空室內(nèi)不凝結(jié)氣體抽出，提高U型熱交換器的換熱效率。
Vacuum hot water boiler uses the change of heat-media water to exchange heat. The heat created from fuel burning is absorbed by heat-media water. When the temperature rises to the saturation point under vacuum, the water evaporates to steam, completing the first phase of change. The volume of the saturation steam is quite small. It rises fast in the vacuum room and heat exchange occurs in the vacuum room with the condensing device. The steam then is condensed to form water, releasing condensed heat, completing the second change phase. The condensed water flows into evaporation room to continue to absorb heat, completing the exchange circulation.
The bottom structure of the vacuum hot water boiler is made of the firebox and heat passing pipes. The upper part of the vacuum room with U-shape pipe heat exchange device. The vacuum is connected to air-pumping unit, making a stable vacuum in the room. The air pump also pumps out the steam that does not condense, increasing the heat-exchange efficiency of the U-shape exchange devise.
