Heat recovery steam generator is energy recovery heat exchanger which recovers heat from a hot gas stream such as combustion turbine or other waste gas stream. It produces steam that can be used in a process or is used to drive steam turbine. They help in converting water into superheated steam in four different segments: evaporator, economizer, super heater & water preheater. Different components are put together in order to meet the operating requirements of the unit. Moreover, they provide thermodynamic link between gas and steam turbines in order to achieve optimum performance in a combined cycle power plant. It can be used widely in energy projects.
Increase in the utilization of cogeneration technology with growing investment in generation capacity expansion is expected to stimulate the growth of the market, for instance, according to the U.S. Energy Information Administration, the contribution of coal in total U.S. energy consumption had declined by 4% in 2018 as compared to 2017. Moreover, expanding industrial sector with shifting trend towards non-conventional energy utilization is anticipated to positively influence the market growth. Rise in the cost of electricity, support of regulatory environment and decline in the capital costs are the factors augmenting the growth of the market. These systems have gained importance in the recent years across energy-efficient industries on account of their ability to minimize carbon footprints and support clean energy initiatives.
The global heat recovery steam generator market is estimated to surpass more than USD 9 Billion by 2027 and is anticipated to record a CAGR of around 4.5% over the forecast period i.e. 2019-2027. The market is segmented by design, rated power, mode of operation & application. The market is segmented by design into horizontal drum and vertical drum, out of which, the horizontal drum segment is anticipated to have significant growth owing to ease of compatibility and low capital expenditure. These systems have compact and flexible designs and are used in gas turbines. They consist of horizontal exhaust fans with heat exchanger tubes that are organized vertically.

The market is further segmented by rated power into 0-30 MW, 30-50 MW, 50-100 MW, 100-200 MW, more than 200 MW, out of which, 0-30 MW capacity heat recovery steam generator is expected to witness growth attributing to expansion of cogenerating units in order to sustain energy and heat consumption in small industrial, commercial and isolated grid networks. Increasing implementation of distributed generation technologies in static energy applications is expected to stimulate the market growth.
On the basis of mode of operation, the market is segmented into cogeneration HRSG and combined cycle plants, out of which, cogeneration heat recovery steam generator is anticipated to grow at a significant rate owing to the technology widely used with cogeneration application in U.S. and in European countries on account of growing adoption of gas-fired technology. Combined cycle plants are anticipated to have growing demand on account of effective design, easy configuration and high efficiency as compared to other alternatives. Moreover, these plants generate heat energy and electricity in one cycle enabling more efficient energy usage than in traditional cycle plant. By application, the market is segmented into chemical, refineries, utilities, pulp & paper, commercial and others.
Energy generation from steam has wide scope of efficiency improvement as the energy loss can be reduced by the implementation of heat recovery steam generator. With rising challenges from the contemporary generation technologies, the efficiency improvement has led to the reduction in the cost of unit energy production and this is expected to boost the market growth.
The installation of HRSG requires huge investment and maintenance of the product requires huge costs. This factor is expected to restrain the market growth during the forecast period. Additionally, the labor is not skilled enough to operate HRSG which may further hinder the growth of the market.
