Heat Exchangers

Heat exchangers are devices used to transfer heat between two or more fluids. They are used for both heating and cooling processes. The fluids may be separated by a solid wall to prevent mixing or may be in direct contact. They are widely used in refrigeration, chemical/ petrochemical processing plants, power stations, refineries and sewage…

Generators.

A generator is a device that converts mechanical energy to electrical energy. The energy generated is used to power our everyday activities in homes, factories, ships. These generators are driven by prime movers such as steam turbines, gas turbines, internal combustion engines or hand cranks which drive the generators to produce electricity. Generators provide nearly…

Steam Turbines.

A steam turbine is a mechanical device that converts thermal energy from steam into mechanical energy. The steam generated from the boiler is heated to a very high temperature and pressure before it passes over the turbines at high speeds. The steam strikes the turbine blades at high speeds causing it to rotate on a…

Boilers.

Boilers are enclosed vessels used to produce steam, primarily for power generation. The steam produced can also be used for domestic purposes such as cooking, heating and sanitation. In power plants, boilers produce steam which are used to drive a turbine which generate electricity. Boilers require a source of heat which heats up the water…

Osmotic Power Station

Osmotic power is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods used are reverse electrodialysis and pressure retarded osmosis. Both processes rely on osmosis with membranes. The key waste product is brackish water. The technology of generating electricity by osmotic method was invented in 1973….

Biomass Power Plants

Biomass is fuel derived from organic materials, a renewable and sustainable source of energy used to create electricity. Some examples of biomass fuels include; forest debris, scrap lumber, crops such as sugar cane, manure, waste residue. With a constant supply of waste from construction and demolition activities to wood not used in paper making to…

Hydro Electric Power Plants

Hydro electric power plants utilize water in huge reservoirs to generate electricity. A dam is usually built across a body of water, creating a reservoir behind it. The dam is built with huge turbines located inside the dam. Outlets are created for the water from the reservoir to flow to the other side of the…

Solar Power Plants

Solar power is the conversion of energy from the sun to electricity. The process involves the use of photovoltaics or concentrated solar power or both. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light to an electric current…

Nuclear Power Plants

A nuclear power plant is a thermal station whose heat source is a nuclear reactor. As with thermal stations, the heat generated is used to produce steam which is used to drive a turbine. The turbine is connected to a generator which produces electricity. As the turbine rotates, it drives the generator that produces electricity….

Wind Turbines.

Wind turbines also known as wind energy converter are used to convert the kinetic energy of the wind into electrical energy. They come in two types, vertical and horizontal. The smallest turbines are used for charging batteries for domestic use while the larger ones are used to generate electricity for homes. Wind farms which refer…
