An industrial boiler is a closed vessel that uses various types of fuels to generate steam. The steam thus generated is used for various industrial heating and humidification applications.

A gear is a rotating machine that enables the transmission of torque through meshing of cut teeth or cogs with another toothed part or rack. The transmission occurs by tandem working of two or more gears using mechanical force to achieve the desired output and thus act as a simple machine. Manual gears are transmission devices that require human effort for operation, and are made of various raw materials such as steel, brass, cast iron, stainless steel, brass, aluminum alloys, and bronze.

Geothermal heat pumps (GHPs) are highly energy-efficient and cost-effective devices for central space heating and cooling. This technology is based on the fact that, at depth, the temperature of the ground is relatively constant, warmer than the air in winter and cooler than the air in summer.The Global GHP System market is expected to grow at a steady rate of 15.50 percent CAGR during the forecast period. The market was dominated by the EMEA region in 2013, followed by the Americas. Some of the major vendors in the market are Carrier Corp., NEURA AG, Robert Bosch GmbH, and Trane Inc.
