Biomass Power Generation Process

바이오매스 발전소는 전형적으로 직접 연소, 혼합 연소 또는 가스화 형태입니다. 직접 연소 발전 방식의 경우 스팀은 목재 폐기물, 농업 폐기물 및 축산 폐기물과 같은 물질의 연소에 의해 발생된 열로부터 생성됩니다. 증기는 터빈을 회전시켜 전기를 생산하는 발전기를 구동합니다. 이 방법으로 바이오매스 물질의 안정적인 공급을 확보하고 이들 물질의 수분 함량을 균일하게 유지하는 것이 중요합니다. 혼합 연소 발전 방법은 안정적인 전기 흐름을 제공하기 위해 바이오매스와 석탄에 의존합니다. 바이오매스 연료가 부족하여 플랜트에 동력을 공급할 수 없으면 석탄이 추가됩니다. 가스화 발전 방법에서, 바이오매스를 가열하여 가연성 가스를 추출하고, 이를 정제하여 가스 엔진 또는 가스 터빈에 전력을 공급하여 발전합니다.

The trend of open system architecture is becoming an important issue with distributed control systems (hereinafter abbreviated as DCSs). To meet this demand, the operation and monitoring functions, and the system generation functions of the CENTUM CS 3000 system are designed to support Windows NT and OLE for Process Control (OPC).

Overview:

As more fieldbus devices are made practicable, demand is increasing for a distributed control system (DCS) which integrates fieldbus devices in its engineering, operation, and monitoring environments. Conventionally, control has been implemented by the dual-redundant CPUs and control bus within a DCS; however, sufficient reliability must be ensured even when it is distributed over field networks.

Overview:

The recent increase of devices enabled for a field network such as the FOUNDATION™ Fieldbus is phenomenal. This has been amplifying a requirement for distributed control systems (DCSs) to be capable of constituting a more pliant and efficient production control system by means of flexible connections to field networks in addition to traditional 4 to 20 mA signals.

Overview:

The environment surrounding process control systems has changed dramatically as the performance of personal computers improves and the Windows operating system advances, there has been a move towards the trend of open architecture.
