“…Apros is a commercial flowsheet-based tool for modelling and dynamic simulation of thermal-hydraulic processes. Apros has been used for modelling and simulating various industrial thermal-hydraulic systems, including nuclear power plants [71], combined heat power plants [160], renewable energy production systems [161], [162], as well as pulp and paper mills [70]. This simulation tool offers libraries of simulation components for common process equipment.…”

“…Among commercially available simulation software, only a few tools have demonstrated the capability in system wide dynamic simulation of CFB plants. In the studies with the Apros tool, 11–13 the process simulation reproduced operation data with reasonable accuracy and computation time, while keeping the modeling effort at the modest level by utilizing the model libraries.…”

“…For the general cases of the dynamic simulation of the CFB furnace as listed above, 8–13 immediate interest of the simulation codes was on the steam dynamics in association with the load control system of the generated power. From the point of steam generation, the furnace side was simplified as the source of energy to the water-steam side, reflecting the lack of interest or the modeling challenges on the specific behavior of the furnace solid dynamics.…”

In a circulating fluidized bed boiler, the large thermal mass and flow characteristics of the solids strongly affect the transient response of the circulating fluidized bed loop temperature, which determines the heat transfer rate to steam flow. Therefore, it is essential to interpret the dynamic response of the solid behavior in the circulating fluidized bed loop for the stable and efficient operation of the circulating fluidized bed boiler. In this study, the dynamic simulation of the solid behavior along with the flue gas flow in a circulating fluidized bed loop was performed by applying the core-annulus approach for the solid-gas flow inside the furnace and selected models for other physical phenomena of the fluidized bed. The circulating fluidized bed loop of a commercial boiler was selected as the target system. Especially, the model simulates the characteristics of the solid behavior, such as the local solid mass distribution, and the solid flow inside the furnace and the circulating solid according to the various operating conditions. These aspects are difficult to measure and quantify in a real power plant. In this paper, the simulated furnace temperature behavior as the representative performance parameter of the circulating fluidized bed loop was discussed along with the qualitative operation experiences reported in the literature. The operating conditions include the feed rate of fuel and air, the particle size, the solid inventory and the solid circulation rate. Furnace temperature behavior was reproduced through the simulation for each operating case in the literature and was analyzed with the solid behavior along with the combustion rate and heat transfer rate of the circulating fluidized bed loop. The simulation enables quantitative evaluation of the effect of the solid behavior on the temperatures of the furnace and return part in the various operating conditions.

“…This work relieves the shortcoming, as we used the commercial Apros (2016) simulation platform, which is traditionally used for the modelling and simulation of nuclear (see e.g. Näveri et al, 2010), and combustion (Lappalainen et al, 2014;Starkloff et al, 2015) power plants, but recently solar power technologies have also been addressed (Hakkarainen and Tähtinen, 2014).…”
