8 Requirements for design of CHP engine rooms construction Placing and space Minimal free space from unit base frame on side of the unit 1200 mm (for both side) Minimal free space in front of electrical switchboard 1200 mm Minimal free space from side where piping connection 1000 mm Engine and generator are coupled and mounted on steel base frame with inserted anti-vibration elements. Transmission of the vibration is minimal. Normally there is no need to prepare antivibration concrete blocks. It is sufficient to calculate the floor as for static weight loading capacity Requirement for engine room floor: dust free concrete or pavement Ventilation of engine room Engine room should be ventilated naturally or by ventilators with minimum three times per hour air change rate. Minimal air change quantity technically required corresponds to the heat lost from cogeneration unit and inlet air to be burned by engine see technical parameters chapter. Other safety requirements for air change will be solved according to locally valid safety rules and standards. To avoid freezing problems and because of better starting conditions it is recommended to keep inside temperature in the engine room not lower than 5 C. Oil handling equipment Oil tank is an option. Usually is mounted on the console on the wall of the machine room. Setting of electrical switchboard Switchboard is part of CHP module for under 200 kwe (including MGM 200) Switchboard is separated single mounted part for over 200 kwe CHP units. Setting of emergency dry cooler Outside a) placed on concrete foundation b) placed on bracket mounted on building Venting (degassing) piping above the roof with min. distance 3 m from possible source of the fire. Exhaust piping a) independent exhaust piping DN100 leaded over engine room piping is made of stainless steel DIN b) leaded into chimney overpressure system required Heating customer system (secondary circuit) Co-generation unit can be optionally equipped with secondary (heating) circuit water pump Three way valve controls return heating water temperature Safety valves on primary and secondary circuits It is absolutely necessary to keep water flow through customer heating circuit when engine is in operation. Danger of exhaust boiler damage. Electrical equipment and power supply system Earthing of the object with earth resistance less then 5 Ω must be supplied to the switchboard. Generator will be fix grounded according to standard ČSN article Arrange power outlet 3f+N+PE/16A close to the unit. Other requirements and space demand Inlet gully for drainage from the exhaust Fresh water including the washbasin in the engine room Specific solution and local requirements is always recommended to consult with the manufacturer of the co-generation unit in advance.
