Energy Saving

Although saving of energy to be developed in life culture, but technology shall also come in help to increase efficiency of systems and equipment. ZETA’s management and engineering team always research and develop “Energy Saving” in all project executions.

Thermal Storage

Thermal energy storage (TES) systems can store heat or cold to be used later under varying conditions such as temperature, place or power. The main use of TES is to overcome the mismatch between energy generation and energy use.

In TES systems energy is supplied to a storage system to be used at a later time, involving three steps: charge, storage and discharge, giving a complete storage cycle. One of the main filed in TES is ICE Bank system.

The ICE BANK responds to many problematic in both industry and buildings. Hundreds of variations of the system allow a made-to-measure solution which will generate substantial efficiency on energy consumption, maintenance, operation and even investment. Moreover, the increased reliability and flexibility will give new ways of designing and operating your installation.

Its working principle is very simple:

To store the cold, a given volume of water is frozen, this phase change between water and ice is actually the most powerful mean to store a great cooling energy in a small volume. To recover this cold, the ice is melted. The efficiency for a load/unload cycle is around 100% thanks to the very good insulation of the tanks.

Waste to Energy

Industrial and household waste has become a valuable alternative fuel source in waste-to-energy plants, either through large scale incineration to power steam turbines or by using gas produced in landfill sites to fuel gas turbines. Modern waste-to-energy solutions can help to ease two major environmental problems by reducing both the landfilling of wastes, and demand for fossil fuels. ZETA’s presented technologies can greatly facilitate this favorable utilization of recovered wastes.

The use of incineration to convert municipal solid waste (MSW) to energy is a long-established method of waste-to-energy production, entailing burning a refuse derived fuel to power a steam turbine. There are a number of other technologies that are able to produce energy from waste without direct combustion, many of which have the potential to produce more electric power from the same amount of fuel than would be possible by direct combustion.

Conversion technologies include an array of emerging technologies that are capable of converting post-recycling residual solid waste into useful products and chemicals, including ethanol and biodiesel, and clean renewable energy. The technologies may be thermal, chemical, or biological. These technologies have been used successfully to manage MSW.

These technologies consist:

  • Hydrolysis (is a chemical decomposition process that uses water to split chemical bonds of substances.)
  • Gasification (is a process that uses heat, pressure, and steam to convert materials directly into a gas composed)
  • Anaerobic digestion (is the bacterial breakdown of organic materials in the absence of Oxygen)
  • Plasma arc (is a non-incineration thermal process)
