This has been assessed as a key factor that is estimated to create lucrative opportunities for the market over the forecast period. A steam generator is a low water boiler of a type similar to a flash steam boiler. The usual construction is a helical coil of water tubes arranged as a single or single tube coil. Circulation is done as a forced circulation boiler in the flow and pumped under pressure.
Growth Drivers
Elevating Growth in Urbanization – The population movement from rural to urban regions, the concomitant decline in the number of individuals living in rural areas, and the manner in which societies adjust to this transition are also included. Urbanization is significantly increasing all over the world and is estimated to increase more over the forecast period. Globally, 55% of people lived in cities in the year 2018, and 68% are expected to do so by the year 2050. The urbanization rate is rising as more individuals are showing the tendency of moving to urban areas. As a result, the demand for electricity services has been growing, which has increased the usage of steam generator for different activities.
Increasing demand for electricity: The demand for electricity is increasing owing to the growing population, urbanization, and industrialization. Steam generators are used in thermal power plants to generate electricity, and the increasing demand for electricity is expected to drive the market for steam generators. Global electricity demand increased by 3% in 2019, with buildings and industry accounting for 80% of the increase.
Rising focus on renewable energy: The world is moving towards renewable energy sources, and steam generators are used in solar thermal power plants to generate electricity. The increasing focus on renewable energy is expected to boost the steam generator market. The world has seen a significant increase in renewable energy generation capacity in recent years. As of the end of 2020, renewable energy had a total installed capacity of 2,799 GW, which represents an increase of 45% compared to 2015.
Rise in Research Spending – Growth in the global market during the forecast period can be further attributed to increased investment in research and development activities to continuously find more viable solutions for steam generations. Research reports show that global R&D spending has more than tripled in real terms since 2000, rising from about USD 680 billion to more than USD 2.5 trillion in the year 2019.
Spiking Electricity Consumption – The world consumed nearly 23,500 TWh (terawatt-hours) of electricity in the year 2020, according to the International Energy Agency (IEA) and it is anticipated to grow more over the forecast period.
Rapidly Growing Chemical Industry – For instance, chemical demand is expected to increase by 8% each year by 2025. By 2025, India's chemical industry will contribute USD 290 billion to its gross domestic product.

End-user (Utilities, Chemicals, Pharmaceutical, Refineries, Pulp & Paper)
The global steam generator market is segmented and analyzed for demand and supply by end user into cell utilities, chemicals, pharmaceutical, refineries, pulp & paper, and others. Out of these types of end users, the utilities segment is estimated to gain the largest market share of about 35% in the year 2037. The growth of the segment can be accredited to the extensive use of steam generators by the utilities sector to recover heat from existing industrial processes. Moreover, based on materials, the austenitic segment is projected to hold the largest share over the forecast period owing to the high resistance to hydrogen embrittlement of this class of steels. Apart from that, the excellent heat resistance, corrosion resistance, and ductility of this steel are projected to drive the growth of this market segment in the coming years. A utility is an organization that maintains the infrastructure of a public service. Utilities are subject to public control and regulation, from local community-based groups to statewide government monopolies. Utility services include telecommunications, power, natural gas, certain transportation services, and water and wastewater treatment services provided by private companies. The telecommunications industry is made up of a mix of large and small players around the world. The AT&T company makes more money than any other carrier with the revenue of nearly USD 172 billion, but China's total telecom asset base is much larger than that. This overarching term has four basic principles, including utility of form, utility of time, utility of place, and utility of possession.
Material (Martensitic, Ferritic, Austenitic)
The global steam generator market is also segmented and analyzed for demand and supply by material into martensitic, Ferritic, Austenitic, and Others. Amongst these five segments, the martensitic segment is expected to garner a significant share of around 30% in the year 2037. Martensitic is a very hard form of the crystal structure of steel. It is named after the German metallurgist Adolf Martens. Similarly, the term can also refer to any crystal structure resulting from non-diffusive transformation. Martensitic is a descriptive term used to refer to martensitic stainless steels. Martensitic stainless steel is a type of steel with added carbon and has a body-centered tetragonal crystal structure. The main difference between austenitic stainless steel and martensitic stainless steel is that the crystal structure of austenitic stainless steel is face-centered cubic, while the crystal structure of martensitic stainless steel is body-centered cubic. Martensitic steel is very useful in automotive applications such as door beams, bumpers, very light and strong lower side rails (sill plates), cross car beams, and beams designed to prevent intrusion into the vehicle interior. Hence, growing sales of vehicles is estimated to boost the segmental growth. For instance, it was noted that global passenger car sales in the year 2020 reached about 63 million units.
