Measuring instruments and gas analyzers
for the thermal energy and electricity production


Fuji Electric measuring instruments support professionals in the thermal energy and electricity production during each phase of their production process in order to:

  • reduce production cost
  • increase yields,
  • extend the service life of installations,
  • guarantee the quality of the finished product.

Boiler

A boiler is a closed container in which water or other liquids are heated or vaporized to provide steam or hot water to other equipment or facilities.
Fire, high temperature gas or electricity are used as heat sources for boilers.

 

 Water tube boiler

Two drums are arranged high and low, connected to each other by a number of water tubes, through which the water circulates.
The tubes are heated by combustion gas to produce steam.

HOW TO CHOOSE THE INSTRUMENTATION FOR the boiler ?

 

industriAL BOILER

Feed Water Control (FWC): keeps the water level in the drum constant.
Automatic Combustion Control (ACC): Controls fuel and air flow rates to improve combustion efficiency while ensuring safety and preventing pollution, and maintaining constant vapor pressure

ChIMNEY 

The chimneys allow the emission of combustion gases.
The combustion gases are blown by a draft fan towards the chimney. They are then rejected by the chimney to be dispersed in the atmosphere.
The height of the chimney should be determined taking into account the effect of weather conditions, surrounding geography and constructions, as well as the spread of regulated pollutants.

This is why it is essential to have air pollution monitoring equipment.

 

HOW TO CHOOSE THE INSTRUMENTATION FOR THE CHIMNEY ?

  • Flue gas humidity measurement and flue gas flow measurement
  • Dust measurement
  • Gas emissions monitoring (CEMS continuous emission analysis system)
  • Temperature measurement and control of the flue gas
  • Pressure measurement and control of the flue gas

 

The production of electricity from fossil fuels (coal, oil, natural gas) takes place by transforming thermal energy into electrical energy.

Steam turbine

A steam turbine uses high-temperature and high-pressure steam to rotate shafts of electric generator.


HOW TO CHOOSE INSTRUMENTATION FOR THE STEAM TURBINE ?

  • Pressure measurement for the steam turbine (steam, air)
  • Pressure control for the steam turbine (steam, air)
  • Flow measurement for the steam turbine (steam, feed-water, fuel, air, flue gas)
  • Flow measurement for the steam turbine (steam, feed-water, fuel, air, flue gas)
  • Temperature measurement and temperature control for the steam turbine
  • Oxygen measurement for the steam turbine (combustion control)
  • Oxygen control for the steam turbine (combustion control)
  • Gas emission measurement for the steam turbine

Cogeneration power plants (Combined heat and power plants)

Cogeneration is simultaneous production of electricity, by gas turbine which  runs by combustion of fuel, and by steam turbine which uses the wasted heat  from gas turbine.
It is a highly efficient power generation system. Cogeneration  plants can reach efficiency ratings higher than 50%.
Environmental impacts can  be further reduced by using LNG as fuel, because LNG emits no SOx nor dust  when combusted.

HOW TO CHOOSE INSTRUMENTATION FOR THE COGENERATION ?

  • Pressure measurement for the cogeneration (steam, air)
  • Pressure control for the cogeneration (steam, air)
  • Flow measurement for the cogeneration (steam, feed-water, fuel, air, flue gas)
  • Flow measurement for the cogeneration (steam, feed-water, fuel, air, flue gas)
  • Temperature measurement and temperature control for the cogeneration
  • Oxygen measurement for the cogeneration (combustion control)
  • Ogyxen control for the cogeneration (combustion control)
  • Gas emission measurement for the cogeneration

Gas turbine

A gas turbine, also referred to as "gas  turbine engine," is a internal combustion  engine fueled either with fuel oil or gas.
The combustion gas drives a turbine to  generate electric power.
Due to the high  output capacity, gas turbines are used to  supply power during peak.

HOW TO CHOOSE INSTRUMENTATION FOR THE GAS TURBINE ?

  •  Pressure measurement for the gas turbine (steam, air)
  •  Pressure control for the gas turbine (steam, air)
  •  Flow measurement for the gas turbine (steam, feed-water, fuel, air, flue gas)
  •  Flow measurement for the gas turbine (steam, feed-water, fuel, air, flue gas)
  •  Temperature measurement and temperature control for the gas turbine
  •  Oxygen measurement for the gas turbine (combustion control)
  •  Ogyxen control for the gas turbine (combustion control)
