District heating - Import export

Engines for combined heat and power plants are operated with different fuels, including hydrogen, natural gas, biogas, sewage gas and special gases, plus diesel and other liquid fuels. In an exhaust gas heat exchanger, the hot exhaust gas from the CHP engines or CHP gas turbines is cooled, in the process heating water, a water-glycol mixture or thermal oil. This thermal energy can be used in a local or district heating system or for other industrial purposes.

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.

Colloide designs and builds customised energy centres which generate heat which can then be distributed to buildings or district heat networks. We can also incorporate CHP units within the energy centre, providing electricity along with heat and a low carbon heat and power solution. Our energy centres are often designed to have more than one energy source, allowing the plant operator to vary the energy sources in relation to the energy demand and the best value for money at a given time. The energy sources may include: Gas fired boilers. Biomass boilers. Heat pump. Oil fired boilers. Combined Heat and Power (CHP) unit Our centres are engineered to include the energy sources, thermal stores, instrumentation, control systems, pumping and pipework network – building in as much flexibility as possible so that the plant can be operated as efficiently as possible.
