CDQ Waste Heat Recovery Boiler

CDQ Waste Heat Recovery Boiler

CDQ waste heat boiler is used by coking industry, the inert gas is used as a medium to cooling high-temperature coke, the absorbed inert gas is passed to the boiler, and then fed into the coke oven by circulating fan for recycling, to achieve high-temperature waste heat recovery.

CDQ device has a good energy saving, reduce costs, reduce environmental pollution, sets of high quality coke and many other advantages. I developed this type of waste heat boiler has been widely used, it is an effective solution to the particular problem of boiler seals, wear, expansion, etc., fully able to adapt to the CDQ system load changes.

Rated Capacity:

5~50t/h

Waste Heat

Boilers Structure

CDQ Waste Heat Recovery Boiler

1. 80% waste heat can be recovered by using the coke dry quenching technology.

2. Coke-quenching boiler operates under negative pressure. If the sealing is not good, the leaking oxygen will cause coke combustion in the coke quenching tank, and the leakage of corrosive smoke will aggravate the corrosion of the heating surface.

3. Steam produced by CDQ boiler is used for generate electricity, emissions of SO2 and CO2 comes from fuels (oil, gas, etc) combustion is reduced.

Auxiliary equipment

CHIMNEY

CHIMNEY

Carbon steel material, the diameter is bigger than common manufacturers, exhaust gas temperature is lower than others.

ASH BLOWER

ASH BLOWER

Use air pulse shock wave soot blower for ash removal, significantly effective, simple operation, high degree of automation.

DEAERATOR

DEAERATOR

Take use of high quality deaerator, remove oxygen from water and prevent boiler oxygen corrosion.

WATER PUMP

WATER PUMP

We adopts the stainless vertical pump with low noise, stainless impeller and pump body.

Steam header

Steam header

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.
