The increasing investments being made in the industrial sector in many countries, especially emerging economies such as India and China, are fueling the rapid growth of numerous industries such as the petrochemical industry in those countries. The boom of the industrial sector is a major factor responsible for the soaring requirement for boilers across the globe. Moreover, the growing requirement for energy efficient devices and systems is further pushing up the sales of boilers in several countries around the world.  

Besides the aforementioned factors, the flourishing food processing industry is also boosting the sales of boilers all over the globe. Moreover, the rising initiatives being taken by various governments for promoting the progress of the food processing industry are positively impacting the demand for boilers. For example, the Indian government is providing numerous tax incentives to the small and medium enterprises (SMEs) operating in the food processing industry for setting up plants and expanding their business operations, which is, in turn, propelling the requirement for boilers in the country.

Because of the above-mentioned reasons, the usage of boilers will increase tremendously in industries, which will, in turn, cause rapid expansion of the global boiler market in the future years. In simpler terms, a boiler is defined as a vessel, closed on all sides, in which water is first heated and then circulated, either as steam, superheated steam, or hot water for providing heating, electricity, or power. Water tube and fire tube are the most commonly used types of boilers all over the world. 
Between the two boiler variants, the usage of the fire tube boilers is presently being observed to be significantly higher mainly because of their lower initial costs, easier handling, and higher fuel efficiency. Furthermore, the fire tube boilers have numerous applications in multiple sectors, owing to which, the sales of these boilers are considerably higher than the water tube variants, which are mainly used in the applications requiring less capacity section boilers.
