District networks for customers and companies

The centralized heat production and its distribution through district heating networks, in the short and long range, is increasingly used for big buildings, used as dwellings, offices or administrative functions, as well as for municipalities and other users with high thermal requirements.

Thanks to the high versatility of use, the Tatano district heating networks can be adapted perfectly to different types of applications: from the in-house micro-network to a complex of few utilities such as terraced houses, up to a macro-network for the district heating of entire neighborhoods and small communities, ensuring reliability, high energy efficiency and low fuel and management costs.

In the micro-networks, the wide product portfolio and the high system expertise of Tatano express the maximum potential, since the heat generator, located in the power plant, is also supplied directly by Tatano.

In high power ranges, the focus is on the implementation of bio-energy countries, usually in rural areas where there is enough biomass available for heating most of the buildings.

District heating is a system for the distribution of thermal energy produced centrally with innovative technologies towards decentralized users.

A district heating network can be seen as a group of small thermal power stations (substations) which, unlike traditional power stations, are interconnected to form an intelligent, dynamic and highly efficient distribution network called "Smart Thermal Grids".

The district heating heat source may consist of a biomass heating system or residual heat and waste from electric cogeneration plants.

District heating has an extremely simple operation that can be summarized in three main phases:

  • The water in the primary circuit (general distribution network) is heated by the thermal energy production system (possibly cogeneration) and brought to the operating temperature: it can be around 90 ° C or, in the case of overheated water, around 110 ° C.
  • Once it reaches the user place, the primary thermal carrier fluid passes through the substation to give off the heat transported to the secondary circuit, which feeds the user system. This fluid will supply the heating system and the production of domestic hot water.
  • After transferring heat to the user place, the heat transfer fluid of the primary circuit returns to the central heating system to be reheated and start a new cycle.

 

Advantages and benefits for the protection of the environment and society

  • District heating, with the same thermal energy produced, generates a lower amount of CO2 compared to a traditional system composed of autonomous CTs.
  • It allows the reduction of costs for the production of thermal energy thanks to the high efficiency of the system and the maximum versatility in the choice between the different fuels.
  • It Eliminates the costs of construction and maintenance of small thermal power stations in each user, facilitating the use by end users with a greater security than the traditional thermal power system.
  • It Guarantees an accurate measurement of energy consumption through heat metering systems, with consequent cost savings for each individual user.
