A district heating is a centralized system of heat generation and distribution that aims to provide domestic hot water (DHW) and heating to different buildings and facilities.
A district heating consists of 3 parts:
This is the part where the heat is generated, usually by a heater, and from which it is distributed in the form of heating and hot water.
It is in charge of delivering the hot water to the final consumers.
It is the part closest to the end consumer where the heat exchange between the fluid coming from the boiler and the water takes place to provide DHW and heating service.
The biomass district heating is a system able to supply heat in the form of sanitary hot water and/or heating to a network of buildings and installations by means of the combustion of material coming from a biological process.
In recent times, this type of system has become popular, especially in Europe due to certain advantages such as:
Biomass heaters in a district heating system are responsible for generating, through the combustion of material from a biological process, the heat needed to supply services such as domestic hot water (DHW) or heating to the network of buildings and facilities.
This type of biomass heaters and its combustion system must be focused on reliability and continuous operation of the system, due to the constant demand they must meet.
A district heating heater works more than 8,000 hours a year, so it must have an automatic cleaning system and a robust design that prevents unwanted shutdowns.
The type of heater in a district heating can vary between different heat transfer fluids, such as hot water, steam or thermal oil, depending on whether it is a district heating for pure electricity generation or part of a cogeneration.
Although the most popular system is the pusher grate system for combustion of woody biomass, some heat networks work with combustion systems adapted to other fuels, such as fluidized bed, dust injection or fixed grates.
Sugimat, as a company specialized in the manufacture of industrial boilers, has two district heating:
As part of the Bricker Project, Sugimat supplied a 1.5 MW cogeneration unit.
Supply of a 1.5 MW boiler for the generation of 220 kW electric and 1200 kW thermal at 80 °C.
