Boilers Structure

WNS Series Oil/Gas Fired Hot Water Boiler

1. Adopts horizontal type three pass structure and large diameter corrugated furnace, has large combustion space, could absorb the thermal expansion effectively.

2. The spirally corrugated tube is used to strength the disturbance of flue gas, the heat transfer efficiency is 2 times of common tube.

3. The boiler shell use aluminium silicate board for heat preservation, has low heat loss, increase the boiler thermal efficiency.

4. Equipped with multiple safety protection devices, such as pressure controller, pressure transmitter, water level alarm, safety valve, etc. To ensure the boiler safe operation.

Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.

Water softener

Water softener

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.
