By means of on-siteinvestigation, inspection,interior experiments, theoreticalanalysis and calculation, a detailed analysisis carried out on the causeof the partialcollapse accident about a waste-heat boiler steel structure in a cement plant of Hunan province of China. The resultsof inspectionand analysis show that: as a key part of load transfer, the connection weld of long thin steel plate is poor in quality, meanwhile, the detail of beam-column connection can not meet the requirement of rigid joint stipulated by the design, which are the main causes for the collapse accident of boiler steel structure. Based on the analysis of accident cause, some problems worthy of consideration are put forward to the design and constructionof this kind of structure, such asthe weld procedure and quality control of long thin steel plate connection weld, etc.

Industrial Waste Heat

In order to improve the utilization rate of industrial waste heat and improve the fine design level of waste heat power station, this paper constructs the mathematical model of waste heat boiler and steam turbine, and puts forward the optimization design method of thermal system of waste heat power generation project. By using typical cases, it is proved that there is the optimal design pressure of HRSG, which makes the power generation of the system maximum, and provides a method to improve the power generation of HRSG.

The installation to be discussed in this paper was one of the first gas generator, power turbine, centrifugal compressor design combinations to be put in ground (as opposed to airplane) power applications. As a consequence the control systems, waste heat boiler installation and other parts of the facility proved to be other than adequate for continuous duty industrial plant use and as such, has gone through a subsequent development period to overcome the many problems that were encountered. This should be kept in mind as one reads the article. The present-day industrial gas generator units incorporate simplified and reliable control systems and other successful features as a result of this earlier experimental and prototype installation. Revisions to the Phillips Petroleum Company Dumas Helium Plant Pratt Whitney GG3C gas generator and related equipment have greatly increased onstream capabilities. Replacement of unreliable controls and electrical relays has decreased unwarranted shutdowns from 80 hr in 1963 to 8 hr in 1967. Improvements in lubricating oil have increased the time between oil changes from 300 to 3000 hr. Design changes in bearings, exhaust hood, and the lubricating oil system have increased the gas generator’s reliability. The Cooper-Bessemer RT-48 free power turbine has operated maintenance-free since startup. Cooper-Bessemer’s latest design has solved the reaction turbine hood stress cracking problem. Use of this type facility in helium plant service offers advantages, but lack of flexibility has caused a considerable amount of product loss at Dumas Helium Plant.

Steam Cycle

An experimental project is now underway to demonstrate the advantages of the Kalina cycle technology. A Kalina Cycle Experimental Plant (KCEP) will be built as a 3 MW bottoming cycle using the waste heat from a facility within the Energy Technology Engineering Center (ETEC), a U.S. Department of Energy laboratory located in Canoga Park, California. The design of the experimental plant is presented, including the process flow diagram, heat and mass balance, and specifications for the plant’s major equipment; the waste heat boiler, turbine generator and distillation/condensation subsystem. Using a mixture of ammonia and water at a mass ratio of 70/30, and a new condenser design based on absorption principles, the Kalina cycle plant will attempt to demonstrate its superiority over the Rankine steam cycle. Based on single pressure designs at comparable peak cycle temperatures, the Kalina cycle’s output should exceed that of the steam cycle by 25 percent.

Thermodynamic Performance

California State University, Sacramento, has constructed and put into service a stand alone cogeneration laboratory. The major components are a 75 kW gas turbine and generator, a waste heat boiler, and a 10 ton absorption chiller. Initial testing has been completed with efforts concentrating on the gas turbine engine and the absorption chiller. A two part thermodynamic performance analysis procedure has been developed to analyze the cogeneration plant. A first law energy balance around the gas turbine determines the heat into the engine. A Brayton cycle analysis of the gas turbine engine is then compared with the measured performance. While this engine is quite small, this method of analysis gives very consistent results and can be applied to engines of all sizes. Careful attention to details is required to obtain agreement between the calculated and measured outputs; typically they are within 10 to 15 percent. In the second part of the performance analysis experimental operation of the absorption chiller has been compared to that specified by the manufacturer and a theoretical cycle analysis. While the operation is within a few percent of that specified by the manufacturer, there are some interesting differences when it is compared to a theoretical analysis.
