AB  - During the sizing of the radiant zone in boilers and furnaces, the most often used method is the Lobo-Evans model. This method is based on the perfect mixing model for flue gas flow inside the fire box, which represents a conservative or pessimistic flow pattern. This paper presents a different, optimistic model which is based on the plug flow for flue gas flow which results in the largest possible heat duty. The proposed model is given in two distinct forms-integral and numerical. As shown in the paper, the integral model results in small deviations with respect to the numerical model and, as such, is well suited for the engineering practice. Paper also presents an engineering approach to the calculation of the conductive heat transfer through the membrane wall, which is shown to be sufficiently accurate and simple for engineering calculations.

AB  - Paper presents new equations for calculation of stress intensification factors, sustained stress indices and flexibility factors for large diameter-to-thickness ratio elbows (i.e., D/T>100). The proposed equations overcome the need for pipe stress engineers to use numerical analyses in order to evaluate the piping which falls outside of the scope of typically used piping design codes. Regression analysis of the newly proposed equations is based on an extensive numerical database developed specifically for purposes of this paper, alongside with the data (both numerical and empirical) found in the open literature. Proposed equations prove to be a better fit to the database than the existing equations and have been shown to be applicable not only for large pipes, but also for normal piping (having D/T  lt = 100) typically found in industrial plants. In case of the adoption of the proposed procedure, it is implied that the proposed equations should be applied to all the bends within a piping system subject to the analysis and not only to the selected bends.

AB  - In the engineering practice, it may often prove necessary to provide quick and relatively accurate estimates of piping routing and material requirements in very early stages of a project. In these cases, there is typically no time to perform detailed pipe stress analysis in order to obtain accurate routing, which allows for sufficient piping system flexibility, and the designer is constrained to the use of rule of thumb approach and good engineering judgment. This approach, although often used, may prove challenging in many situations, one of which is establishing sufficient pipe loop dimensions. Method proposed by the authors in Jacimovic and Ivosevic (2020, "Shortcut Method for Pipe Expansion Loop Sizing," ASME J. Pressure Vessel Technol. 142(4), p. 041505) provides a procedure for quick estimation of U loops, while the present procedure aims to provide additional procedures for estimation of L and Z bends, thus completing the circle of shortcut methods for quick estimation of expansion requirements of piping systems.

AB  - Paper deals in-depth with the topic of sustained stress indices applicable to 90 degrees elbows based on non-linear finite element analysis models. A comprehensive overview of the existing literature sources is given in the first part of the paper, showing that there are little sources which deal specifically with this topic and that the ones that do exist result in important scatter of the results. As a result, more than few of the existing sources are non-conservative in their nature. Dedicated non-linear finite element studies have been performed on shell and solid models which are used in conjunction with the regression analysis in order to obtain explicit equations which can be used to calculate both in- and out-plane sustained stress indices in 90 degrees pipe elbows, which can then be used in the typical pipe stress analysis. Newly proposed equations prove to be a good fit for the numerical data, showing little deviation as shown by the correlation parameters presented in the paper. Final part of the paper presents a dedicated section on the high wall thickness elbows and shows the relationship between elbow wall thickness and maximum stress location. It is shown that beyond certain thickness, the maximum stress location shifts from the typical failure location (i.e., side wall) to the locations which are not typically expected (i.e., intrados or even away from elbow). This shifting may have an important effect on the theoretical models which assume failure location.

AB  - In the engineering practice, it is often necessary to define supporting scheme and expansion loop requirements for piping distribution systems in very early phases of a project. While placing pipe supports is a relatively easy and straightforward task, providing accurate loop locations and dimensions for hot piping systems can often be challenging. In the early phases of any project, it is impractical, costly and time consuming to perform detailed stress analysis of a piping system to provide expansion loop dimensions, and therefore approximate methods are often used. Comprehensive overview of these existing procedures most commonly used in the engineering practice is given in this article. However, the fact is that most of the existing methods are based on the inconvenient charts and tables with scarce background data. Procedure proposed in this article is based on over 150 expansion loop models and provides a simple and accurate analytical method to size and verify piping loops. Two fully worked examples show the simplicity and accuracy of the proposed model and its advantages over the methods typically used in the engineering practice.

AB  - This paper presents alternatives to Kalina cycles typically used in place of the organic Rankine cycle in biomass power plants. Overviews of both Rankine and Kalina cycles are given alongside the possibilities of using biomass as a viable energy source and recommended guidelines from the engineering practice for selection and management of these cycles. Benefits of Kalina novel bottoming cycle (and the alternative cycles presented herewith) over the Rankine cycle are the higher thermodynamic cycle efficiency and lower capital expenditures combined with the possibility of using low-grade heat sources, such as biomass or waste heat from exhaust gases. Analysis of ammonia-water binary system under various operating conditions has been performed for all the proposed cycles based on the published references and it has been shown that the proposed alternative models prove to be simpler and to have similar or even greater thermodynamic efficiency compared with the Kalina novel bottoming cycle.

AB  - Thermoplastic piping is becoming increasingly important in the general industry applications. Owing mainly to their corrosion resistance, light weight and low maintenance requirements, plastic pipes can be found in many industry branches with their use becoming ever more widespread. Despite this fact, up to date there are no piping codes or other sound references which would clearly and univocally define the procedure and parameters for thermoplastic pipe stress analysis. Paper discusses stress analysis and design of thermoplastic piping systems and proposes a dedicated procedure for their calculation. Presuming isotropic and perfectly plastic material properties, stress intensification factors, which do not exist in open literature, have been determined using finite element and regression analysis. Results presented in the paper show that the new equations result in a much better fit and much lower mean deviation than existing equations for metallic piping. Although stress intensification factors determined based on the finite element analysis can be found even in some of the most advanced piping codes in use today, it could be recommended that in future dedicated tests on physical specimens be made in order to confirm the presented findings or suggest better equations.

AB  - Removal of oxygen from feedwater is of paramount importance for safe boiler operation. Insufficient extraction of oxygen in deaeration vessels will lead to limited efficiency of oxygen scavengers and unsafe plant operation. The presented sizing procedure for packed deaeration columns is based on the similarity theory between heat and mass transfer and existing procedures. The goal of the proposed technique is not to achieve optimization of column dimensions, but to ensure that there is no undersizing of the packing height. This approach is justified considering the relatively low capital costs of deaeration columns in boiler plants. The proposed equations are based on an experimental setup involving several hundred operating regimes which have been verified and confirmed to have a high degree of accuracy.

AB  - Although contact condensers are extensively used for various industrial applications, procedures for calculation and sizing these vessels are scarce in the open literature. However, before new and reliable calculation procedures can be derived, it is important to obtain properly verified experimental results. In this paper, a novel validation procedure is introduced for the case of condensation of the complete amount of vapor that enters the device. The proposed procedure is based entirely on the theoretical model that must always be fulfilled in the aforementioned case. This fact makes it very useful in verification of experimental results for contact condensers with no vapor outflow.

abstract = "Although contact condensers are extensively used for various industrial applications, procedures for calculation and sizing these vessels are scarce in the open literature. However, before new and reliable calculation procedures can be derived, it is important to obtain properly verified experimental results. In this paper, a novel validation procedure is introduced for the case of condensation of the complete amount of vapor that enters the device. The proposed procedure is based entirely on the theoretical model that must always be fulfilled in the aforementioned case. This fact makes it very useful in verification of experimental results for contact condensers with no vapor outflow.",

AB  - Reboilers are essential for the proper work of distillation and stripping columns. Hereby the intensity of axial mixing along the reboiler (Peclet number) is used for the reboiler separation efficiency modeling and estimation for binary systems. Two fully worked examples show that the separation (Murphree) efficiency varies significantly depending on the adopted reboiler flow model. Murphree efficiency ranges between 1.40 and 0.663 in example 1, and between 1.962 and 1 in example 2. The general conclusion is that the reboiler performance must be considered carefully in the case of design of the new plants,as well as in the case of "brown field" projects.
