结构特点及技术优势
Structural features and technical advantages
电真空热水锅炉的下半部结构为水室，水室壁上安装有不锈钢加热管，通过电加热管将电能转化为热能，上半部为蒸汽空间，其中插入了由不锈钢管组成的列管式热交换器。由于锅炉整体是在负压状态下，故绝对安全。炉内的热媒介，在锅炉运行的全过程中，不进、不出、不增、不减，只封闭在锅炉的真空室内，在锅炉的传热管与热交换器之间传递热量。炉内的热媒介是完全脱氧的纯净水，无腐蚀，无水垢。
The lower haf of the electric vacuum hat water boier is a water chamber.A stainiess steel heating tube is installed on the wall of the water chamber, The electric heating tube converts electrical energy into heatThe upper haf is a steam space in which a row of stainless steel tubes is inserted. Tube heat exchanger.As the whole boiler is under negative pressure. it is absolutely safe.The heat mediun in the furnace does not enter, exit, increase, or decrease during the entre operation of the boiler.it is only enclosed in the vacuum chamber of the boiler and transers heat between the heat transfer tube of the boiler and the heat exchanger.The heat medium in the furnace is pure water with complete deaxidation,no carrosion and no scale.

安全Security
锅炉运行时的内部绝对压力为0.02~0.065Mpa，此压力低于大气压力，即机组处于真空状态，因而不会发生爆炸，同时上部低压蒸汽空间安装有机械防爆装置，在电器保护措施全部失效的情况下，也不会因为锅炉超压而发生危险。
The intemal absolute pressure of the electric vacuum hot water boier during operation is 0.02-0.065Mpa, which is lower than the atmospheric pressure, that is. the unit is in a vacuum stabe, so it will not explode. At the same time the upper low-pressure steam space is equipped with a mechanica exploslan-ereof device to protect the slectica applances. if al the measures fall, there will be no danger due to boiler overpressure
环保 Environmental protection
由于采用电热管加热给水，电能直接转化为热能，不需要采用燃烧的方式将化学能转化为热能，不会排放有害气体及飞灰，不会产生灰渣，完全符合环保方面的要求。
Since the electric heating tube is used to heat the feed water, electric energy is directly converted into heat energy, and there is no need to use combustion to corvert chemical enerey into heat energy. no harmul gas and fiy ash are emilted. and no ash is generaled, whch fuly eets the reauremers of environmental protection
高效High efficient
电真空热水锅炉电加热管被热媒水完全包围，更好的吸收加热管散发出来的热量，同时锅炉外侧用硅酸铝针刺毯进行炉体保温，更大限度的降低锅炉散热损失，以提高热效率，整体热效率可达98%以上。
The electric heating tube of the electric vacuum hot water boiler is compietel surrounded by the heating medium water, which can better absorb the hea emitted by the heating tube. At the same time, the aluminum silicate needie bianke is used for the funace body insaton on the ouside of the baler which greatly reduces the boier heat oss. in order to imprave the therral efficiency the owerall thermal effioiency can reach more than 98%. 
便捷 Convenient
本系列锅炉结构紧凑，安装运输方便，锅炉整体安装在坚固的底座上，可整体对锅炉进行吊装和放置，同时侧边设有爬梯可方便地安装其他辅机设备;上部换热器采用不锈钢直管，两侧水室可同时打开，对不锈钢管进行清理和维修。
This series of boilers are compact in structure, easy to install and transport The boiler is installed on a solid base, and the beller can be hoisted and placed as a whole. At the same time, there is a ladder on the side for easy installation of other auxiliary equipment; the upper heat exchanger adopts stainless steel straight The water chambers on both sides of the pipe can be opened at the same time to clean and repair the stainiess steel pipe.
使用寿命长Long service life
由于真空锅炉内部是大气密闭的整体，而在运行时，中间介质水中的氧析出，排出炉外，炉内长期不会发生氧腐蚀一次性加入小量的热媒水，有限小量的钙镁离子，运行时不增不减，因此锅炉内部不发生结垢，增加了锅炉使用的寿命，是一般锅炉寿命1.5~2倍。换热器部分采用不锈钢管制造，耐腐蚀，设计使用寿命超过20年以上。
Since the inside of the vacuum boiler is an airtignt whoe, and during operationthe oxygen in the intermediate water is separated outand dischaned out of the fumace. There will be no oxygen corasan inthe lumace for a long time A small amount of heat medium waterand alimited amounocaicium are added at one tme Maonesium ion dces not increase or decrease during aperation, so no scaiing occurs insine the boiler. which hcreases he sevioe life oi the boier, which is 1.5 to 2 times the service ile of the general boder.the heat exchanger par is made of stainless stee tube which is coroson resistant and has a desioned service tfe chmore than 20 years.

控制准确A ccurate control
真空热水锅炉选用PLC 可编程 控制器，控制器可根据外
界负荷变化，全自动调节运  行，热7 K温度可在20 -85℃之间
自由设定，设定后机组能自动调节温度，确保恒温。同时控制
器还可自动检测燃烧器和炉体内部的故障，发出声光报警。
The vacuum hot water boiler uses PLC programmable controller. The
controler can auomalically adjust and operate according to externel bad
changes.The hot water temperature can be set freely between 30 and 85 0
After setting, the unit can automatically adjust the temperature to ensure
constant temperature.. At the same time, the controller can also automatealh

delect the laults in the burner aht alsms. and the fumace bady. and send out sound ans

一机多用 Multi-usage
一台机组可配置多个换热器，供应不同温度、不同用途的热水，如中央空调用水、卫生热水、工艺热水等。公司遵循最大能量配置’原则，确保每个换热器单独供热时都能达到最大供热量，使用户能以最小投资获取较好效果。
One unt can be equipped with muliole heat exchangers to supnly hal
water of different temperatures and purposes. such as central air conditoning waler, sanitary hot water, process hot water. etc. The comeeny falows th principle of 'maximum energy configuration’ to ensure that each hea exchanger can achieve the maxmum heat supply when heating separately, so that users can obtain the best results with minimal investment
