Boilers Structure
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.
Auxiliary equipment
Advanced Burner
Usual burner brand: Italy Baltur, Ecoflam, Riello, Unigas Germany Weishaupt, Finland Oilon. It is general mechanical proportion adjustment, two-stage fire.
Control System
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
Economizer
We adopts aluminum alloy fin tubes, its heating transfer area is 2-10 times larger than the bare tube, has a good heating transfer and mechanical property.
WATER PUMP
We adopts the stainless vertical pump with low noise, stainless impeller and pump body.
Steam header
Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.
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.
