According to Straits Research, the global steam boiler market size was valued at $18.07 billion in 2025 and is projected to grow from $18.7 billion in 2026 to $24.63 billion by 2034, registering a CAGR of 3.5% during the forecast period 2026–2034.
A steam boiler, often called a steam generator, is a device that generates steam by heating water. A steam boiler is an equipment or a component that uses heat from the combustion of a fuel source to heat water within a boiler, producing steam for various applications, including heating and power generation. The general efficiency of a steam boiler is between 80% to 90%. This efficiency is partially attributable to partial oxidation, radiation loss, and other thermal losses. A steam boiler's steam is utilized for power generation, industrial applications, and heating.
Rising demand for steam boilers from end-use industries is a significant factor propelling the growth of the steam boiler market. In addition, a spike in investment in the power generation industry due to increased energy demand contributes significantly to the growth of the global steam boiler market. However, a rise in investment in renewable energy power generation, rigorous government regulations regulating greenhouse gas emissions from conventional fuel sources, and a high initial cost for steam boilers hinder the market's progress. In contrast, technological developments in steam boilers for high heating efficiency and the modernization of aging infrastructure for power generation are predicted to provide growth opportunities for the top competitors in the steam boiler market. However, the implementation of stringent government regulations regarding environmental pollution from coal-based and other conventional fuel sources, as well as the rapid growth of the renewable energy sector, are the primary factors impeding the growth of the global steam boiler market in the coming years.
The demand for Steam Boilers from End-user Industries and Increased Investment Towards Adding Power Generation Capacity to Drive the Global Steam Boiler Market
Developing economies such as China, India, Japan, and Brazil are driving the rise of the steam boiler market by continuously and consistently increasing their energy demand. This is because steam boilers are used as a source of power generation when energy demand is higher than usual, allowing industries to continue manufacturing and other processing activities uninterrupted. In addition, industries such as oil & gas, manufacturing, power generation, paper & pulp, and processing have witnessed a boom in demand for steam boilers due to their rapid startup, high efficiency, and dependability. This aspect is anticipated to considerably contribute to the growth of the global market over the forecast period.
In the coming years, an increase in oil and gas exploration and production, expansion projects, and other construction activities in developing and developed nations will fuel the demand for steam boilers. Numerous oil and gas sector activities, including refining, crane operation, oil well digging, on-site pre-stressed concrete building, welding operations, and heating & processing, require consistent electric power and steam. This growing demand for energy and steam can be fulfilled by a steam boiler, which significantly contributes to the expansion of the global steam boiler market.
The steam boiler industry is continuing to see enormous expansion thanks to the steady flow of technological advancements that have been made in product manufacturing over the past many decades. This is because of growing urbanization and industrialization rates, which have increased power demand. In addition, the market for steam boilers in Asia-Pacific, the Middle East, Latin America, and Europe presents growth opportunities due to rising investments in the region's new power generation infrastructure. This has resulted in a dramatic growth in the capacity for producing energy, which, in turn, increased the need for steam boilers.
North America is expected to dominate the market with the largest share and a CAGR of 3.4% during the forecast period. In North America, the United States is the foremost producer and consumer of steam boilers. Canada and Mexico are other countries in the region offering enormous steam boiler market potential. Food processing, power generating, and oil & gas sectors, which are steadily expanding in the region, generate a significant need for steam boilers.
Asia-Pacific is expected to hold the second-largest market share of USD 6,916 million with a CAGR of 3.9% during the forecast period. China, Japan, India, South Korea, and Australia are the leading contributors to this region's market growth. In addition, Asia-rapid Pacific's population growth and economic expansion fuel the expansion of the food processing, chemical, pharmaceutical, oil & gas, and healthcare industries.
