The structure of gas fired water tube condensing boiler is arranged as drum longitudinal type “D” shape, it’s quickly assembled boiler with water tubes, has the characteristics of high steam quality, sufficient output, and high thermal efficiency, etc. The layout of economizer at boiler tail could effectively reduces exhaust gas temperature and improve boiler thermal efficiency.
The structure of furnace water cooling wall and convection gas flue is membrane wall, have good sealability, and effectively reduce refractory brick quantity and maintenance workload. This type oil fired water tube condensing boiler is delivered as a whole when leave factory, convenient for transportation, and has a short install period.
Characteristics of Condenser
1. By equipped with the condenser (economizer) at the tail of the boiler, make full use of flue oil heat, decrease the exhaust smoke temperature, the thermal efficiency is high than 97%.
2. The condenser uses fanned tubes to increase the heating surface, improve heat transfer efficiency.
3. The fanned tube adopts stainless steel to avoid low temperature corrosion.
High efficiency gas fired water tube condensing boiler is widely used for industry production and processing, and it could meet the large steam needs. It could used for textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc.
1. Product 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) Burner ---- Customer could designate the brand
2) Electric Control Cabinet ---- Customers could choose PLC or touch screen control cabinet, also, the brand of electric elements could be designated.
2) Water Pump ---- Customer could designate the brand, and the boiler could adopt variable frequency water supply, save energy and decrease operation cost.
4) Economizer ---- The boiler could equipped with economizer based on customers’ requirement, to improve boiler thermal efficiency.
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) Boiler Shell color ---- Customer could designate the color of boiler shell, elegant appearance.
2. High Quality Assurance
1) Before manufacturing a boiler, the boiler design drawing has to 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.
