Market Overview
Power plant boilers play a critical role in electricity generation by converting water into steam using coal, gas, nuclear, or renewable energy sources. These steam-generating systems are integral to the operation of thermal power plants, contributing significantly to global energy production.
As nations move toward decarbonization, traditional boilers are being replaced or retrofitted with advanced systems like supercritical and ultra-supercritical boilers. These systems operate at higher pressures and temperatures, leading to increased boiler efficiency and reduced carbon emissions. Moreover, the transition toward hydrogen-ready and biomass-fueled boilers is becoming a prominent trend.
Global Power Plant Boiler Market size and share is currently valued at USD 23.57 billion in 2024 and is anticipated to generate an estimated revenue of USD 40.03 billion by 2034, according to the latest study by Polaris Market Research. Besides, the report notes that the market exhibits a robust 5.4% Compound Annual Growth Rate (CAGR) over the forecasted timeframe, 2025 - 2034
