Professional Coke Oven Gas Collection System Single Chamber Pressure Regulation System Solution Provider

Achieve full automation of Ascension pipe(AP) operations during the coke oven production process, improving the level of automation, production accuracy, and efficiency.

Stabilize and reduce GCM pressure, improving the control of fugitive emissions during the charging and early coking phases.

Ensure linked actions with rapid and accurate operation and feedback responses. Interlock control guarantees the reliable sequence of AP water seal cover, water seal valve, and high and low-pressure ammonia water valve operations, preventing smoke and fire incidents, and meeting environmental production requirements.

Maintain micro positive pressure at the bottom of the oven chamber during the coking cycle, effectively improving coke quality, protecting the coke oven body, extending the service life of the coke oven, and enhancing production efficiency.

Reduce high-temperature, high-heat positions at the top of the coke oven, prevent safety production accidents caused by misoperation, ensure high reliability of operations in emergency situations, effectively reduce safety production accidents, and meet safety production requirements.

SCPR^®- SAC System

Based on the coke oven operation plan and oven cars signals, the fully automatic SCPR-SAC system includes automatic opening and closing of the AP water seal cover, automatic opening and closing of the water seal valve, and automatic switching of high and low-pressure ammonia water.
SCPR^®-I Single Chamber Pressure Regulation System

While achieving the automatic operation of the SCPR^®-SAC system, it stabilizes and reduces the GCM pressure to a slight positive pressure, meeting the emission control requirements during the charging phase and ensuring no long-term negative pressure at the bottom of the oven chamber during the coking cycle.
SCPR^®-II Single Chamber Pressure Regulation System

With the addition of a dedicated regulation device, while the SCPR^®-II system operates automatically, the device ensures precise regulation of GCM pressure from slight positive to negative pressure, maintaining precise pressure control at the bottom of the oven chamber.

Dalian Pu Cheng Control System Co., Ltd. has designed and developed the Single Chamber Pressure Regulation (SCPR^®) system for coke oven gas collection. This system intelligently controls the pressure in the gas collection pipe while optimizing the ammonia spray system's suction capacity and coverage. It addresses the process requirements for large suction capacity needed during coal charging in different coke ovens and resolves the issue of smoke leakage from the oven door in the early coking stage. By regulating the pressure of the single oven chamber, it meets the requirement of maintaining a slight positive pressure at the bottom of the oven chamber in the late coking stage.

Building on this foundation, Dalian Pu Cheng has developed various single-chamber pressure regulation devices to meet different process requirements:

Device model	Application	Applicable for GCM pressure	Device control accuracy ※
SCPR^®-SAC※1	Top, stamp charging battery	180Pa ～ 80Pa	Automatic opening and closing system of standpipe
SCPR^®-Ⅰ※2		180Pa ～ - 50Pa	±3%
SCPR^®-Ⅱ※3		180Pa ～ -350Pa	±1%

※1SCPR^®-SAC system: Effectively enables automatic opening and closing of the ascension pipe(AP) system.

※SCPR^®-I system: Ensures no negative pressure in the oven chamber throughout the entire coking cycle under different GCM pressures(+180P~-50Pa).

※SCPR^®-II system: Achieves no negative pressure at the bottom of the oven chamber throughout the coking cycle under GCM negative pressure operation, with output gas pressure that can be linearly adjusted.

The SCPR^® single chamber pressure regulation device from Dalian Pu Cheng is suitable for new and existing coke ovens. It allows for the retrofit of various SCPR^® systems without production interruption by adding detection and control equipment. This ensures the automatic operation of the ascension pipe system or single-chamber pressure regulation. It effectively solves the problem of unorganized emissions during the coke production process, meets environmental protection requirements, upgrades the automation level of the coke oven gas collection system, improves the reliability of coke production safety, and extends the service life of the coke oven.
