Flue Gas Desulfurization (FGD) System Market

Report Overview

The Global Flue Gas Desulfurization (FGD) System Market size is expected to be worth around USD 37.4 billion by 2034, from USD 23.4 billion in 2024, growing at a CAGR of 4.8% during the forecast period from 2025 to 2034.

The Flue Gas Desulfurization (FGD) System Market represents a critical segment of global air pollution control, driven by rising emission standards and the continued reliance on coal-based power generation across emerging economies. The market focuses on systems designed to remove sulfur dioxide from industrial exhaust streams, ensuring compliance with tightening environmental regulations worldwide.

Thermax Limited is seen as a strong contender in cost-sensitive and mixed-fuel industrial markets in 2025, where compliance deadlines meet space and capex limits. Its advantage often lies in localized manufacturing, faster project turnaround, and the ability to bundle FGD with boilers, energy efficiency, and broader air pollution control solutions for a single-vendor approach.
