BC Bugwood Envirochem Services Inc. CHP system, a positive steam pressure is maintained downstream of the power turbine. This greatly reduces the power extraction as the cycle is sensitive to this factor. Expansion turbines lose efficiency at low flows unless their rotational speed is increased. However, steam is quite voluminous and turbine impeller sizes prevent compensating speed increases. A practical small-scale steam system will have an overall system electrical efficiency of about 10% - 12%. Steam systems have inherent dangers associated with their boilers. Local regulations determine the training and registration requirements of operators. Highly trained personnel, where needed, add to the operating cost of steam systems. Exiting flue gas is typically about 315°C - 345°C, which limits flue gas cleaning options. CHP heat is offered as low-pressure steam, which limits the transport distance when used for district heat. CHP heat demands reduce the system electrical efficiency significantly. Few steam systems are offered below 3 MWe. They are custom configured and are difficult to justify economically, even in a CHP application. 5 Attemporator 10 Superheate Boiler Turbine 6 7 Co-generation process 1 Economizer 9 2% blowdown Feed Pump 4 8 Figure 4.3.1 Condensate return and makeup 3 Deaerator Small Steam CHP System Organic Rankine Cycle: The organic Rankine cycle (ORC) differs from the steam system in that it uses an organic fluid (or synthetic oil) in place of steam. The system operates in a closed loop by re-circulating the working fluid between selected pressures. The peak pressure and temperature is again limited by material considerations and will be similar to small-scale steam systems. However, the lower system pressure can be increased and still be matched to the low-heat reservoir temperature. The higher pressure exiting the turbine means a reduced volume flow. A greater mass flow of organic working fluid is required to compensate for its lower enthalpy but this is partially mitigated by the effects of the higher molecular weight of the fluid. The net benefit is that a smaller turbine impeller can be used. The turbine impeller can be as small as 20% of the size of an equivalent power steam system turbine. To reduce the inherent hazards of steam boilers, ORC systems typically employ a separate heat recovery circuit. ORC systems will use an independent combustor with heat recovery from the hot flue gas. Thermal oil is circulated through a heater in the combustor flue gas to collect heat and transfer it to the ORC power cycle. This approach bypasses the need for a registered steam operator in most jurisdictions. The double circuit adds complexity to the system and thus system Page 40PDF Image | IDENTIFYING ENVIRONMENTALLY PREFERABLE USES FOR BIOMASS
