Product Description
Introduction

Exhaust gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam. Otherwise, the exhaust gas boiler could be used in oil/gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine.
 
Generally, the exhaust gas boiler is installed in gas duct, generate steam by absorbing the flue gas waste heat, and decrease the exhaust gas temperature. Compare with the ordinary steam boilers, exhaust gas boiler do not burn fuels. It could change waste into wealth, has the advantages of energy saving and low production cost. Because of the flue gas temperature is relatively low when enter into the boiler , the heating area is much larger. 

Main Exhaust Gas Boiler Types
 
Horizontal three wastes mixed burning blown gas boiler
Carbon rotary kiln exhaust gas boiler
Tank type carbon exhaust gas boiler
Coking exhaust gas boiler (after burning)
Hazardous waste incineration exhaust gas boiler
CDQ exhaust gas boiler, glass kiln exhaust gas boiler
Sintering machine  exhaust gasboilers, sulfuric acid waste boiler
Oil catalytic cracking of exhaust gas boiler
Non-ferrous metal smelting exhaust gas boiler
Steel smelting exhaust gas boiler
Pure low temperature exhaust gas boiler in cement kiln
Gas turbine exhaust gas boiler
 
Zhongding Boiler could design the boiler according to the user’s specific requirement.


Operate Process
 
Flue Gas:
The high temperature flue gas generated by waste material or waste liquid flows into the furnace, working medium inside the boiler will take it into the front and end smoke chamber in order, then high temperature flue gas becomes low temperature flue gas, and then discharged into the atmosphere through chimney.
 
Water:
Drum – Down pipe – Tube bank heat receiver – Riser pipe – Drum (water pump supply water after consumption)



Application

The exhaust gas boilers are widely used for various industries, such as glass industry, coking industry, pyrite-based sulfuric acid product industry, fertilizer plant, chemical industry (methyl alcohol, ethyl alcohol, formaldehyde, synthesis ammonia), cement manufacturing, cogeneration and concentrated heating for carbon rotary kiln, etc.


Advantage

​1. Boiler Customization
 
Zhongding Boiler dedicates to the research and design of waste heat boiler for many years, and it has achieved four national patents. Rely on the advanced technology and equipment, excellent quality and service, and supported by a large number of scientific research institutes, such as Xian Jiaotong University and Tsinghua University, Zhongding Boiler absorbs multi achievements and experience, and keeps on optimization and technology innovation. Based on smoke gas temperature, volume, and composition, Zhongding Boiler could customize the specific waste heat recovery boilers, to meet the operating requirement and maximum the boilers’ effectiveness.
 
2. High Quality

\

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.  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.
2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
