Oil Gas Fired Water Tube Hot Water Boiler

The structure of natural gas fired water tube hot water boiler is arranged as double drums longitudinal type “D” shape, it’s quickly assembled boiler with water tubes, has the characteristics of sufficient output and high thermal efficiency (97%), etc. The structure of furnace water cooling wall and convection gas pass is membrane wall, have good sealability, and effectively reduce refractory brick quantity and maintenance workload. The layout of economizer at boiler tail could effectively reduces exhaust gas temperature and improve boiler thermal efficiency. This series diesel fired boiler is delivered as whole when leaving factory, convenient for transportation, and has a short install period.

Rated Capacity:

4.2MW~25MW

Pressure:

<2.5 Mpa

Certificate:

ISO 9001, CE, BV, SGS, ASME

Fuel:

Natural gas, LPG, Diesel, Heavy Oil, etc.

Boilers Structure

Oil Gas Fired Water Tube Hot Water Boiler

1. Adopts double drums and arranged as "D" shape, sufficient steam storage and large combustion space, achieve high steam quality and high thermal efficiency

2. The boiler uses whole membrane wall structure and double drum, has compact structure and good flame filling degree, reduce heat loss, reduce refractory brick quantity and maintenance workload.

3. There are economizer and condenser at the tail of the boiler, make full use of flue gas, decrease the exhaust smoke temperature, the thermal efficiency could higher than 97%.

4. Set up inspection hole and manholes on the boiler, convenient for maintenance.

5. Adopts PLC full automatic intelligent control cabient and interlock protection program, to ensure safe and convenient operation.

It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.

Quality

Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.

boiler quality
we choose domestic well-known manufacturer who can provide component report of raw material, to ensure the raw material is qualified. After the completion of raw material procurement, there are specialized technicians in our factory to make sampling chemical composition analysis and physical performance analysis, and we can also provide raw materials inspection report.
We adopt numerical control cutting, which has the advantage of high precision, neat cutting surface, nice appearance and high material utilization.
Boiler manufacturing
Boiler production
We adopt submerged arc fully automatic welding. When each welding process is done, the 100% X-ray inspection will be arranged for every welding seam, which can prevent the defective parts from flowing into the next process.
