Steam Boiler

WDR Electric steam boiler

WDR Electric steam boiler

WDR type electric heating steam boiler uses electric energy as energy source. It is a horizontal high-power boiler. It can be used in single or multiple units in parallel. It has no noise, clean, reduced pollution, and no smoke emission during operation. The furnace body electric control cabinet is separated to prevent the electrical components from aging quickly and affect the service life; the heater components are made of stainless steel electric heating tubes, which have low surface load, high thermal efficiency and long service life; separate small flange connections are used for easy maintenance; Its normal service life is about 20,000 hours, its thermal efficiency is nearly 95%, and it does not emit NOx (nitrogen oxides) to the atmosphere; the operating part adopts a special control system for electric boilers, with grouping and balanced starting functions, and four time intervals can be set to operate every day, which is safe to use Convenience.
Performance advantage
1. Stainless steel electric heating pipes, each group of electric heating elements are connected by centralized beam flanges, which are set independently, with simple structure, high mechanical strength, safety and reliability, and easy replacement.
2. The boiler starts fast, the steam quality is good, the operating load adjustment range is large, the adjustment speed is fast, and the operation is simple.
3. The heating element automatically adjusts the number of heating tube input groups according to the temperature difference and load changes, and can automatically switch the input sequence, which not only saves energy consumption, but also equalizes the running time of each group of heating tubes, thereby uniforming the life of the heating tube.
4. The heating element can also be manually turned on or off, which is convenient for users to flexibly adjust the heating value of the boiler.
5. Using intelligent boiler controller control and display screen, it can display equipment status, operating parameters and fault alarm by setting its working pressure, working time and other functions; it has the advantages of reliable performance, high degree of automation, and convenient use.
6. The outer tank of the main engine is insulated with aluminum silicate board, and both ends are covered with living body packaging, which is convenient for installation and maintenance, and ensures the long-term energy-saving operation of the boiler.
Protective function
1. Leakage: After the control system detects the leakage of the electric heating element, it will automatically cut off the power supply quickly.
2. Water shortage: When the boiler is short of water, cut off the heating tube power supply in time to prevent the heating tube from burning dry. At the same time, the controller sends out a water shortage alarm.
3. The furnace shell is over-temperature: the boiler stops running immediately.
4. Abnormal power supply: the boiler immediately stops running and interlocks sound and light alarms.
