Voorbeeldzinnen

1. The Vsec is determined by continuous flow measurement e.g. before the heat recovery unit.
2. Examples of fuel inputs are any combustibles, steam and other heat imports, and process waste heat used in the cogeneration unit for electricity generation [4].
3. A cogeneration unit operating with maximum technically possible heat recovery from the cogeneration unit itself is said to be operating in full cogeneration mode.
4. Examples of heat other than useful heat are the following: heat rejected to the environment without any beneficial use [3]; heat lost from chimneys or exhausts; heat rejected in equipment such as condensers or heat-dump radiators; heat used internally for de-aeration, condensate heating, make-up water and boiler feed-water heating used in the operation of boilers within the boundaries of the cogeneration unit, such as heat recovery boilers.
5. Including unavoidable thermal energy losses and ‘non-economically justifiable demanded’ heat produced by the co-generation unit.
6. ‘boiler’ means the combined boiler body-burner unit, designed to transmit to fluids the heat released from burning;
7. Fuels used by plants containing at least one CHP unit are to be reported under Autoproducer CHP Plants. Autoproducer Combined Heat and Power (CHP) Plants
8. Fuels used by plants containing at least one CHP unit are to be reported under Autoproducer CHP plants. Autoproducer combined heat and power (CHP) plants
9. The thermal energy required to produce these additional electrical energy outputs has to be excluded from the useful heat output of the cogeneration unit as a whole.
10. The efficiency of the heat pump unit shall exceed the following minimum requirements of the coefficient of performance (COP) and primary energy ratio (PER).
11. For the CHP part, the plant operator shall check the load pattern (useful heat demand) and evaluate whether the unit operates in full cogeneration mode during certain periods.
12. If this is the case, the plant operator shall measure actual heat and electrical energy output from the cogeneration unit for this situation and during these periods.
13. In accounting for that excess electricity, the size of the cogeneration unit shall be assumed to be the minimum necessary for the cogeneration unit to supply the heat that is needed to produce the fuel.
14. Non-CHP electricity means the electrical energy generated by a cogeneration unit in a reporting period at times when one of the following situations occurs: no related heat produced by the cogeneration process or part of the heat produced cannot be considered as useful heat.
15. for the industrial use of the combined production of electric power and heat where it can be shown that the production cost of one unit of energy using that technique exceeds the market price of one unit of conventional energy. The production cost may include the plant’s normal return on capital, but any gains by the undertaking in terms of heat production must be deducted from production costs.
