As emission regulations continue to tighten, many coal-fired power plants have entered the era of ultra-low particulate emissions (≤5 mg/m³).Selecting the right dust-removal technology has become a critical engineering decision that directly affects environmental compliance, operating cost, and long-term system reliability. This article provides a comprehensive technical comparison of Electrostatic Precipitators (ESP), Baghouse Filters, and […]

Accurate temperature measurement is critical in industrial processes, yet technicians often encounter a common problem:the multimeter shows a “normal” resistance or mV value, but the temperature reading in the control system is still wrong. In most cases, the issue is not with the multimeter, but with how the measurement should be interpreted.By understanding the core

In the journey of becoming a skilled instrumentation technician, regular inspections of critical equipment are a crucial step. Such equipment plays a pivotal role in ensuring the smooth operation of production processes. Any malfunction in these systems could lead to significant disruptions. This guide will provide a detailed overview of the essential aspects of regular

A Distributed Control System (DCS) is the core automation platform that ensures safe, stable, and continuous plant operation. To maintain long-term reliability and prevent unexpected shutdowns, a structured routine maintenance program is essential.This document summarizes the key daily, monthly, and quarterly actions required for hardware, software, network infrastructure, and field instrumentation. 1. Hardware Maintenance (Daily

Capacitors are essential components in modern electronics, playing a crucial role in various circuits and applications. Their ability to store and release energy makes them versatile and indispensable. Here is an in-depth look at the primary functions of capacitors: 1. Energy Storage and Release Capacitors can store electrical energy in the form of an electric

Distillation is often perceived as one of the simplest unit operations in chemical processing. In reality, a distillation column is a highly integrated thermal–hydraulic–mass transfer system whose stability depends on the precise interaction of heat input, vapor–liquid equilibrium, internal pressure dynamics, and control strategy. When a column becomes unstable, operators are frequently blamed. However, most

Thermocouple compensation cables play a critical role in temperature measurement systems. They extend the thermocouple signal from the sensing point to the control room while maintaining measurement accuracy. Selecting the correct compensation cable ensures stable signal transmission, reduces cold-junction influence, and minimizes measurement error. This guide explains how to correctly identify different types of compensation

Cable manufacturing is a highly integrated process involving raw material preparation, conductor processing, insulation and sheathing extrusion, quality testing, and final packaging. To maintain stable product quality and support long-term customer reliability, manufacturers must optimize across the entire production chain. This article summarizes eight key dimensions of optimization that significantly enhance product quality, reduce defects,

Industrial instrumentation in chemical plants is highly vulnerable during the rainy season due to moisture intrusion, condensation, lightning surges, corrosion, and cable insulation degradation.This document provides a systematic and actionable protection strategy based on four principles: Prevent Water Ingress • Prevent Moisture & Condensation • Prevent Lightning & Surge Damage • Prevent Corrosion & Short-Circuit

Gas Detection Systems (GDS) are categorized as critical safety systems. Their primary functions—real-time gas concentration monitoring, alarm triggering, and emergency interlock—require extremely high reliability, fast response, and fail-safe communication. For this reason, international and domestic standards clearly state that GDS field detectors must NOT be connected using a shared bus network, including RS-485 multi-drop wiring.A
