실시간 성능 데이터는 에너지 집약도를 낮추는 데 중요합니다
안전하고 신뢰할 수 있으며 효율적인 용해로 운영은 어렵습니다. 가장 중요한 목표에는 연료 대 공기 비율의 최적화, 안전한 작동, 배출량 감소, 환경 규제 준수 등이 있습니다. 에머슨은 고급 공정제어, 동급 최고의 계측, 안전 시스템 및 소프트웨어를 결합하여 가열로 성능을 개선 및 최적화하고 배출을 줄입니다.
안전하고 신뢰할 수 있으며 효율적인 용해로 운영은 어렵습니다. 가장 중요한 목표에는 연료 대 공기 비율의 최적화, 안전한 작동, 배출량 감소, 환경 규제 준수 등이 있습니다. 에머슨은 고급 공정제어, 동급 최고의 계측, 안전 시스템 및 소프트웨어를 결합하여 가열로 성능을 개선 및 최적화하고 배출을 줄입니다.
연료 조성 변화는 연료의 발열량 및 효율적인 연소에 필요한 공기의 양에 영향을 미칩니다. 이로 인해 연소가 불안정하거나 불충분해집니다. 과잉 공기로 작동하면 안전 마진이 증가하지만 에너지 비용 및 배출 또한 증가합니다. 효율성을 안전하게 극대화하려면 연료의 발열량과 일치하도록 이상적인 양의 과잉 공기로 운영해야 합니다.

Micro Motion 코리올리스 유량계 및 밀도계
에머슨의 코리올리스 유량계는 화학 작업에서 질량 유량, 체적 유량 및 밀도 측정 요건에 맞는 최고의 신뢰성을 제공합니다.
Rosemount 무선 컴팩트 컨디셔닝 오리피스 유량계
업계 최고의 비용 효과적 솔루션인 Rosemount 3051SFC 무선 소형 컨디셔닝 오리피스 플레이트 유량계는 안전한 WirelessHART® 네트워크를 통해 정확한 다변량 측정을 제공합니다.
끊임없이 변화하는 규제 요구 사항을 감안할 때, 배출에 대한 제한을 준수하는 데 어려움이 있습니다. 규정 준수를 위한 기술 옵션을 이해하는 것이 최우선 과제입니다. 에머슨의 지속적인 배출 모니터링 솔루션으로 규정 준수를 보장하고 전반적인 성능과 운영에 대한 통찰력을 향상시킬 수 있습니다.
질소 산화물(NOx) 배출 모니터링 및 보고
산업용 연소 플랜트에서 빠르고 정확한 NOx 배출 모니터링을 보장합니다.
밸브 비산 배출
플랜트의 밸브가 비산 배출의 주요 원인입니다. 밸브를 업그레이드할 때마다 현재와 미래의 비산 배출 규정 준수에 더 가까워집니다.
DeltaV 발전된 제어 방식
연소 및 제어 효율성을 위해 기본 측정 및 데이터로 가열로 성능을 효과적으로 분석합니다.
필드 장치 관리
필드 장치의 사전 진단을 통해 장치의 구성 및 교정 상태를 유지하고 효과적으로 운영하여 생산 장비의 신뢰성을 보호할 수 있습니다.
Rosemount CT5100 연속 가스 분석기
에머슨의 Rosemount CT5100 연속 가스 분석기는 공정 가스 분석 및 배출 모니터링용으로 개발된 최초의 하이브리드 레이저 기반 분석기입니다.
AMS Optics 소프트웨어 플랫폼
상태 모니터링, 워크플로우 통합 등을 위한 통일된 소프트웨어 솔루션으로 자산을 전문적으로 관리할 수 있습니다.
가열로에 대해 자주 묻는 질문
대부분의 시설에서 대체 연료는 더 저렴하기 때문에 선택되며, 이는 일반적으로 품질 및 에너지 값이 변할 수 있다는 것을 의미합니다. 대부분의 가열로 연소 제어 시스템은 연소를 제어하기 위해 용적 유량이나 압력을 사용합니다. 연료의 열 함량을 측정하는 것이 더 빠르고 효율적입니다. 이 문제는 연료 공급 장치에 에머슨의 Micro Motion Coriolis 질량 유량계 또는 Rosemount 가스 크로마토그래프를 사용하여 해결할 수 있습니다. 두 가지 측정 중 하나를 Fisher 제어 밸브를 포함한 정밀 유량 제어와 결합하면 최적화된 솔루션을 얻을 수 있습니다.
연소 공기가 너무 많으면 효율성이 감소하고 너무 적으면 공정이 불안전하므로, 최적의 공기량이 있는지 확인하기 위해 잔류 산소를 측정하는 것은 중요합니다.
열효율은 총 연료 에너지 입력에 대한 유용한 열 출력의 비율입니다. 이는 연소 공기 예열, 폐열 회수 또는 버너 성능 최적화 등 여러 방법을 통해 개선될 수 있습니다.
화학 산업에서 다양한 유형의 가열로가 일반적으로 가열 응용 분야에 사용됩니다. 열분해 용광로는 에틸렌 생성과 같은 크래킹 응용 분야에 사용되는 다목적 히터입니다. 개질로는 스팀 메탄의 개량(SMR)을 통한 수소 생산과 같은 촉매 개질 공정에 사용됩니다. 증기 보일러는 발전 및 열 교환을 위한 고압 증기를 생성합니다. 열 유체 히터는 정밀하게 온도를 제어하기 위해 열전달 유체를 사용합니다. 소각로는 폐기물 처리에 사용되며, 축열식 히터는 폐열을 회수하여 재사용합니다. 직접 가열 방식의 가열로는 공정 유체를 화염에 직접 노출시킵니다. 이러한 가열로의 선택은 공정 요구사항, 연료 가용성 및 환경 고려 사항에 따라 달라집니다.
