Product Description
Introduction
Industrial hot water boiler is widely used for hot water supplying or heating in enterprise, hotel, school, hospital, gym, swimming pool, laundry, civil architecture, etc. The fuel could be oil, gas, coal, biomass, electric, etc. Zhongding Boiler concentrates on the invention of high-tech environmental protect and energy saving industrial hot water boilers, including circulating fluidized bed boiler, waste heat boiler, oil gas fired boiler, coal/biomass fired boiler, and electric heating boiler. As the professor of industrial boiler manufacturing, Zhongding boiler takes several measures to solves the problems of boilers during the industrial production, such as poor quality, safety issues, low efficiency, and high combustible matter content in ash, etc. Moreover, Zhongding Boiler could customize the boiler products based on customers’ requirements.

Advantage
1. Boiler Customization 

Zhongding Boiler owns a mature R&D and design team, and cooperates with multiple scientific research institutions for a long time, i.e. Tsinghua University and Xi’an Jiaotong University. Zhongding Boiler could customize the boiler based on the requirement of customers, water quality and fuel characteristics, to meet the operating requirement and maximum the boilers’ effectiveness.

\

1) Grate  ----  Based on the fuel characteristics (size, humidity, and volatility, etc.), equipped with different grate, such as fixed grate, chain grate, and moving grate, etc. The chain grate could divided into small flaker grate, chain belt grate, bar grate.
2) Burner  ----  Customer could designate the brand.
3) Secondary Air Device  ----  Based on the fuel characteristics, could equipped secondary air device, to decrease the heat loss of incomplete combustion, improve boiler thermal efficiency.
4) Air Preheater  ----  For the fuel with high humility, could equipped with air preheater, uses the waste heat of flue gas to heat the air, and improve the combustion condition, decrease heat loss form incomplete combustion heat loss.
5) Water Treatment Equipment  ----  Based on the water quality, could equipped with different water treatment equipment, generally, there are soften water treatment and reverse osmosis water treatment equipment.
6) Electric Control Cabinet  ----  Customers could choose PLC or touch screen control cabinet, also, the brand of electric elements could be designated.
7) Water Pump -- Customer could designate the brand, and the boiler could adopt variable frequency water supply, save energy and decrease operation cost.
8) Dust Removal Device  ----  Based on the requirement of dust emission in different area, could equipped with different dust removal devices (multi-tube cyclone dust catcher, bag dust collector, double towers desulfurization)
9) Economizer  ----  The boiler could equipped with economizer based on customers’ requirement, to improve boiler thermal efficiency.
10) Variable Frequency Motor  ----  The boiler could adopt variable frequency water supply pump, blower fan and induced draft fan, etc., save energy and decrease operation cost.
 
2. High Quality Assurance 

\

1) Zhongding Boiler owns a professional design engineer team, before manufacturing, every boiler design drawing will be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) Nondestructive testing will be done to ensure the welding quality, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) Hydrostatic test will be done to ensure the leakproofness and strength of boiler pressure parts, generally, the testing pressure is 12.5 times of rated working pressure.
6) All the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international quality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
 
3. Safety Assurance

To ensure the safe operation of industrial boilers, Zhongding Boiler make several measures on boilers, including boiler instruments, auxiliaries and control systems, etc.
 
1) Reliable boiler auxiliaries and multiple safety protection devices, such as pressure controller, pressure transmitter, water level alarm, safety valve, etc.
2) Adopts PLC control cabinet and full automatic interlock protection program, has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and phrase-lacking or overloading of motor, etc.
3) Equipped with explosion doors, prevent deflagration in furnace, discharge high energy, and automatic reset as well, to ensure the boiler operate safety and efficiently.
4) For oil gas boilers, adopts complete gas manifolds and protection system, including filter, pressure regulating valve, and solenoid valve, etc., to ensure the safety performance of fuel.
5) For electric boilers, all the electrical components have the CE and CCC certification, to guarantee the safety operation and long working time.
 
4. Professional Installation and After-sale Team

1) Professional engineer installation team offer the door to door installation and after sale service. The boilers will operate smoothly and safety, and you will get them without worries.
