Dates of signing contract / commissioning :
Mar.12th 2015/ the end of December of 2019
Contents of project:
- to match with 5.5 stamp charged coke oven with capacity of 1.09t/a
- Hot coke transfer system
- Coke bucket car
- CDQ chamber and gas supply device
- Charging device
- Coke discharging equipment
- Coke discharging chute
- Gas circulating system including primary dust collector, Secondary dust collector, Circulating fan, Thermal tubular heat exchanger, etc
- Coke handling system
- CDQ boiler system
Features of major design:
-CDQ chamber
The CDQ chamber, which is positive pressure cylindrical vertical brickwork, has a shaft kiln structure.
- Primary dust collector
The primary dust collector is the gravity settlement tank type de-dusting device, which is used to remove coarse coke fine contained in the circulating gas.
- Secondary dust collector
The secondary dust collector adopted is the multi-cyclone type separating dust collector which is suitable for CDQ process to further separate small sizes of coke fine from the circulating gas. In this way the abrasion of coke fine to the blade of the circulating fan will be reduced.
Scope of contracting:
ACRE has been responsible for complete basic engineering, detailed engineering, equipment & material supply, training, commissioning and technical service.
Project Highlights:
- CDQ chamber, which is positive pressure cylindrical vertical brickwork, has a shaft kiln structure to decrease the investment of construction and cost of operation.
- adopt inclined double-flue structure to prevent the duct outlet from being blocked by part of coke blocks that blew up by the cooling gas and extend the service life of refractory of double-flue.
- The primary dust collector top is constructed with a simple and steady brick-arch structure. The inner wall of arch top and upper arch wall of the primary dust collector suffer from current flushing and coke fine abrasion.
