Thermal-economic analysis of heat-matched industrial cogeneration systems

Recent federal incentives in the U.S. concerning tax credits, fuel-use exemptions, and facilitation of sale of electric power to local electric utilities have greatly stimulated interest in industrial cogeneration. In particular, the ability to sell excess or all cogenerated electric power (i.e. arbitrage) has widened the options available to a potential cogenerator. In the present paper we consider a comparison of alternate cogeneration plants with an existing steam-only plant in terms of energy conservation and engineering economics. The concept of marginal cost of production is applied throughout. The criterion of economic selection is acceptable incremental rate of return on incremental investment based on the challenger-defender test of successively greater capital costs. As an example, coal-fired topping steam turbines as well as natural-gas-fired gas turbines and oil-fired diesels with waste-heat boilers are considered to replace a gas-fired steam-only plant and provide a range of electric power for the same thermal load.

Simulation analysis of a repowered double fuel CHP plant including a non‐evaporative heat recovery boiler

A repowering analysis of a conventional, coal‐fired industrial combined heat and power (CHP) plant by means of a gas turbine (GT) and heat recovery boiler (HRB) has been taken into consideration. The existing system, operating in one of the Polish chemical factories consists of coal‐fired boilers, back‐pressure extraction turbines, condensing turbines and steam‐fed district heat exchangers. Two variants of modernization have been proposed and examined from the thermodynamic, environmental protection and economical points of view. The first one includes HRB for preheating the boiler feed water, condensate, and district water, while the steam turbine (ST) system and coal boilers work without any structural changes. The other advanced variant introduces live steam superheaters to HRB. The coal‐fired boilers, in this light, supply only saturated steam (which is introduced into HRB), so they have to be readjusted by replacing the existing superheaters with convective vaporizers for proper flue gas cooling. Such a scheme ensures a considerable reduction of exergy losses in HRB and therefore leads to deeper flue gas cooling and a decrease of coal consumption for the assumed process steam and district heat demands. Heat and process steam demand duration curves for a typical year of operation of the plant have been adapted as input data. The mathematical model of the whole CHP plant has been built on GateCycle and Visual Basic software. The model includes design and off design analyses of boilers, steam and gas turbines and also takes into account shut‐down necessities, concerning machines during their operation outside the acceptable area of their key parameters (e.g. the minimum steam flow in the condensing section of the turbines from the point of view of rotor cooling). The computation was run many times for different sets of input data, read from the demand duration curves. Finally, the yearly values of solid and gaseous fuel consumption, as well as electricity production have been calculated. Both proposed variants of the repowered CHP system have been compared with the existing plant by means of the incremental cumulative economy of chemical energy and pollutant emission. An approximate classical economy analysis net present value (NPV), discounted pay back (DPB) has also been carried out. The whole computation has been replayed for several market GT models. The results obtained lead to the conclusion that repowering of a coal‐fired plant by means of a GT and HRB is a very effective way to improve the thermodynamic and environmental protection aspects of power and heat generation. The introduction of the live steam superheater into HRB provides additional advantages in these fields. The economic results indicate DPBs from 3 to 11 years, depending on the situation at the electricity and fuel markets. Copyright © 2004 John Wiley & Sons, Ltd.

Industrial use of geothermal energy at the Tasman pulp & paper co. ltd's mill, Kawerau, New Zealand

Tasman Pulp & Paper Co. Ltd's mill at Kawerau has an annual production capacity of 380,000 tonnes of Newsprint and 200,000 tonnes of Kraft pulp. The mill electrical requirement amounts to 128MW. Geothermal steam has a significant impact on the mill energy balance and contributes around 35% of the mills steam requirements. There are five geothermal to clean steam heat exchangers with a total capacity of 140t/hr of 345kPa saturated process steam and two boiler feedwater heaters which supply two chemical recovery boilers and three power boilers. Additional geothermal steam is used to heat combustion air and operate shatter sprays at the recovery boilers. A 10MVA geothermal turbo-alternator exhausts steam to a black liquor pre-evaporator and a heat exchanger to heat clean process water. All the available geothermal condensate is collected and treated in a condensate recovery plant to meet quality specifications for boiler feedwater. This meets all of the feedwater requirements of the geothermal heat exchangers plus the make up for the recovery and power boilers. Geothermal water separated in the borefield is used by Bay of Plenty Electricity in two Ormat binary cycle turbines which generate 2.0MW nett. The discharge from the binary cycle plant is also processed in an experimental pilot scale Precipitated Silica plant to recover silca which is used as a newsprint additive. The remainder is discharged through a serpentine canal to the Tarawera river.
