Gas: Natural Gas

Equipment: CHP unit, CG200-NG*2, 400kW-electricty, 526kW- heat

A PowerLink gas CHP is in operation at a site in Russia to supply power and heat/hot water to a 4-star hotel. This hotel is made up of 20 floors, with a total area of 22,752m2. During peak hours, energy is provided to a total of 250 guest rooms. With the demand of hot water, three boilers were equipped to provide outputs for heating, catering, washing and cleaning facilities.

Why to have CHP installed in a hotel?

Each year, the hotel spends a huge amount on utility costs, but with the CHP unit, electricity and heat are provided, not only that it will cut down the spending, but it will also supply the hotel to remain in normal operation if there is a power cut to the building. The importance of having energy supply to a 4-star international hotel is excessively high. The backup of electricity to the facility would help to avoid financial loss, as well as the hotel reputation.

The installation period of 15 days, main installation work includes connecting the pipework for the supply of gas, lining all the cables to supply power, also to the grid, and  setting up the heat distribution management equipment to ensure the heat is able to reach every corner of the building. The operation hours of the two units are from 6am to 10pm each day on a typical day. This accounted for the peak hours where energy is likely to be used the most. It then automatically shuts down during non-peak hours. When the unit is off, any need on energy will be coming off the grid.

With the two CP unit, a minimum of 209 tons of hot water is produced each day for washing and radiator heating. The output temperature is of 85oC, and of course, the heat distribution management system would come in operation to carry water to where it needs, and the correct temperature out of the taps. Regarding the electricity, 3800kW is provided each day, all supplied to the hotel, and any extra needs will be supplied by the grid. In incidences such as power failure, the unit is equipped with an ATS system to allow automatic start of the CHP units.
