Opis:: This paper presents a model unit demonstrating the possibility of using a PBCHP10VB CHP unit driven by a piston combustion engine fed with gas fuels for heat and power cogeneration. A mobile unit available in the Department enables heat and power cogeneration at any place with available gas fuel, e.g. compressed in a pressure tank or from a production and transmission system. A radiator is connected to the unit’s heat connection for demonstrative purposes – this is the simplest model of a network using the heat generated by the unit, with the possibility of easy connection to another network for heating rooms and/or tap water instead of this radiator. Any three-phase load (e.g. a single phase converter) can be connected to the unit’s power connection. A constructed mobile power generator fed with alternative gas fuels (e.g. biogas) is described which can be used in the field in a biogas system for power generation with simultaneous heat recovery. The results of the first preliminary tests on the effect of the type of gas fuel used on the obtained electrical and thermal power and on the composition of exhaust gas from the driving combustion engine are presented. A plan for further tests is also outlined.

Opis:: The present paper is the result of the author's research project no. 4 T12D 030 28 on the "Analysis of the actual technical and operational parameters of gas CHP sets" carried out by him in the years 2005-08, and financed by the Ministry of Science and Informatization in Warsaw. The primary scientific objective of the Project was to establish, compare and analyze the actual values of basic technical, operational and economic parameters for different CHP (Combined Heat and Power) sets driven by gas piston engines, operated in Poland. An analysis of the techniques of fuel gas utilization in piston engine-driven cogeneration sets, being currently used (and also likely to be used in the future), finding their application in combined energy management, has been made within the Project, and a review of the operational conditions of a dozen or so CHP sets operated in Poland, fed by biogas, mine gas from hard coal mine demethanization has been carried out. The results of this analysis have been included in the present monograph which, in addition to the review of the conditions of CHP set operation, provides conclusions that have also utility importance, and therefore can well be useful in making the optimal design of a combined energy system consisting of combustion heat- and power-generating sets.

Opis:: This paper presents a concept and a technical analysis of a co-generation power set with a combustion engine powered by syngas produced in the process of wood waste gasification. The set is composed of a wood waste gas generator fitted with a filter system, a combustion engine, a current generator and heat exchangers. The foundations of the gasification process are described together with the most common solutions used worldwide. Moreover, the methods of adapting spark-ignition and compression-ignition engines to be powered by syngas produced in the wood waste gasification process are presented. The advantages of the presented solution and its possible applications in industry are shown. The assumed technical parameters of the set are as follows: mechanical-electrical energy – 200 kWh, heat recovered from the gasifier – 250 kWh, heat recovered from the engine – 200 kWh. The concept and design of the module cogeneration set is the effect of actions taken by the Institute of Automobiles and Internal Combustion Engines and by the Institute of Thermal Power Engineering of the Cracow University of Technology.

Opis:: This paper presents the reasons for the development of gas-combined power and heat units and justification for testing the effect of the used gas fuel on the performance of such units. A PBCHP10VB CHP unit driven by a liquidcooled piston combustion engine adapted for feeding with gas fuels is described. The concept is presented for testing the effect of different gas fuel mixtures, including biogas, on this unit’s operation, mainly on the obtained electric power from the current generator and the temperature of the liquid cooling the driving engine heating up output water and on the composition of exhaust gas from this engine. A simple device for obtaining gas fuels containing different combustible gas mixtures is presented. The instruments used to check the composition of the obtained gas fuel and check exhaust gas from the engine are briefly described. The paper describes a test stand for testing the effect of different gas fuels on the operation of a PBCHP10VB gas CHP unit manufactured by Power Blessed Co., Ltd registered in Shanghai, constructed at the Department of Mechatronics and Technical and Information Technology Education of the Faculty of Technical Sciences at the University of Warmia and Mazury in Olsztyn.

Tytuł:: Identification of fouling deposited on the heat transfer surfaces of the steam power plants heat exchangers

Opis:: The term “fouling” refers to a substance, which settles on the heat transfer surface and causes the rise of thermal resistance to the heat transfer process. Sometimes, fouling is regarded as deposit but that term should be only used to fouling in the form of solid. Taking the traditional division of matter states as a criterion for fouling classification, there are three sorts of fouling: the solid ones, e.g. boiler scale, metal oxides, mud; the liquid ones, e.g. lubricating turbine oil and the volatile ones, air as for example an inert gas. Despite maintaining the recommended methods of correction for the steam power plants working agents, such as: the feed water, the boiler water, the condensate and the water vapour, for example by using the phosphate-ammonia correction, both corrosion and deposition phenomena occur in the water and the steam sides of the heat exchanger. Recognition of the type and the amounts of deposits gathered on heat transfer surfaces of the steam power plants heat exchangers is used within the thermal-flow diagnostics and also supports the planning of overhaul and routine repair of these devices. The results of the author’s own experimental research based on the method of spectral analysis were presented in the paper. The study was carried out in order to identify the type of fouling settled on both the outer side (steam side) and the internal side (waterside) on the heat transfer surfaces.

Tytuł:: The assessment of surface layers texture of the fouling gathered on the heat transfer surfaces within regenerative feedwater heat exchangers

surface layer texture
Opis:: The fouling presence on the heat transfer surfaces, both on the waterside and the steam side of the steam power plants heat recovery exchangers usually leads to the loss of their heat transfer capacities. This loss appears owing to the high value of heat resistance of fouling. Furthermore, these deposits are most often formed with irregularities in the surface layers. These textures are usually characterized by a varied, often stochastic and difficult to define, geometric structures. The most common measure of their inequalities is the roughness parameter describing the surface geometry. The fouling surface layer texture can, on one hand, cause enhancement of the heat transfer process, but on the other hand, it may contribute to an additional increase in thermal degradation of the heat exchanger. Many experimental studies have shown that the greater the unevenness of the heat transfer surface on the waterside of a given heat transfer device, the smaller increase in the thermal resistance of the impurities over time, thereby increasing the amount of heat transferred. It should be emphasized, however, that the rise in roughness results in an increase in the heat transfer coefficient, while simultaneously intensifying the flow resistance of the working medium. Taking into account the heat transfer surface by steam side, the increase in the roughness promotes the formation of a thicker condensate layer, thus impairing the condensate drainage organization. It can be explained by the fact that deposits settle in a sort of quasi-rib effect, although with undefined ribbed grid, it may lead to the overflow of inter-finned passages. The article shows the previously mentioned phenomena and also presents the descriptive quantities for the fouling surface layer texture, based on the results of the author’s own experimental research.

Tytuł:: Evaluation of the thermal degradation process within the steam power plants heat exchangers

Powiązania:: https://bibliotekanauki.pl/articles/244895.pdf

Tematy:: steam power plants
fouling of heat transfer surface
thermal degradation determinants
Opis:: The consequence of the deposits presence on the heat transfer surface of the following heat exchangers: shell-and-tube condensers, the regenerative feed water exchangers, are commonly the loss of heat exchanger capacity, owing to the high value of heat conductive resistance of fouling. The process is more often defined as the thermal (heat) degradation of a given heat transfer device. The symptoms of heat degradation are usually defined as the difference between the values of thermal-flow parameters for the current and the reference state. Moreover, this process always entails an increase in the cost of energy conversion, leading to increasing the emission output of greenhouse gases consequently increasing the environmental degradation. It is worth mentioning that deposits settled on the waterside of heat transfer surface could also initiate the process of tubes obliteration. This phenomenon is characteristic for condensers cooled by seawater in particular. Reducing internal diameter of any single heat exchanger pipe by the deposits cause the rise in flow resistance and also reduce the condenser cooling water pump capacity. Ultimately, it leads to the reduction in water flow rate, resulting in an additional increase in the resistance of heat transfer. Furthermore, reducing the flow rate of cooling water causes the enhancement of the fouling settling rate. The paper describes the above-mentioned phenomena and presents the quantitative determinants of the thermal degradation description for heat exchangers based on the results of the author’s own experimental research.
