Natural Gas-Based Cogeneration Unit

ITEEO specializes in full turnkey implementation, construction, maintenance and service (O&M) of natural gas-powered cogeneration-based (CHP) power stations of 300 kW to 10 MW capacity.

 

Cogeneration technology integrates two processes, generating electricity and producing heat in an effort to accomplish more efficient utilization of the gas. Diesel-powered or turbine-based electricity generation is typically low utilization and involves heat losses due to gas emissions and engine cooling. Cogeneration exploits these heat sources and recycles them for thermal processes. This way an overall efficiency of 65% to 85% is achieved, compared with just 20% to 40% in the single-purpose process. Additionally, the total cost of energy and power generation in a cogeneration system is lower than the production costs in two separate processes.

 

Common uses for cogeneration
  •  Electricity generation for self-consumption and/or for supplying the national grid and for sale to the electricity company

  • Use of the mechanical energy produced as a substitute for electricity to power mechanical industrial machinery

  • Production of steam and hot water through the thermal energy

  • Exploitation of the emitted residual heat to heat air, for industrial products and as a thermal lubricant

  • Use of the residual heat for heating processes or to produce refrigeration

  Steam boilers 

ITEEO supplies, installs and maintains steam boilers based on water tube technology, fire tubes or electricity.

Steam is produced by feeding water into a pipe system which collects heat produced in its surroundings through burning oil or gas.

 

This is a closed system, whereby the steam vapors increase its temperature or its pressure or both.

 

Several terms are commonly used in the steam industry:

 

Wet steam

Is water vapor at chemical equilibrium with liquid water. Wet steam has a univalent ratio between the pressure and the temperature, which is determined from the water’s equilibrium between gas and liquid. If the pressure of the wet steam is known, then it is possible to know its temperature, and vice versa. Wet steam usually serves in facilities where a high, stable temperature is needed. As long as the pressure remains constant, energy is supplied through water condensation, and the temperature remains unchanged.

 

Superheated steam -(“dry” steam)

Is steam whose temperature is higher than the temperature suitable for its pressure according to the steam tables, or - equivalently - its pressure is lower than the pressure suitable for its temperature. Superheated steam is created when wet steam comes in contact with a high temperature surface and may reach hundreds of degrees centigrade. Superheated steam is usually used in steam turbines. In these installations, the presence of water droplets may damage the turbine. By superheating the steam (heating the wet steam until it superheats), condensation of droplets is prevented prior to its passage through the turbine.

 

Steam ton

a term describing the heat transfer power of a steam boiler.

 

Water tube boiler

a term describing a work characteristic of a steam boiler in which the water flows inside the tubes and the fire, which increases the steam temperature and pressure burns in the envelope surrounding the tubes.

 

Fire tube boiler

a term describing a work characteristic of a steam boiler in which the water flows in the envelope surrounding the tubes installed in the boiler, while the fire, which raises the steam temperature and pressure, burns inside the tubes.
