Abstract

The article considers the possibility of joint application of mathematical processing and computer 3D modeling of the technological process line for processing ash and slag waste from thermal power plants (TPP). The authors suggest considering an approach to the design of the ash and slag waste processing site by mathematical processing and 3D computer modeling. The mathematical processing with the help of E- network device and the creation of a 3D model allows to plan the site for processing ash and slag waste, select the appropriate technology and thereby ensure the environmental effect of both existing and projected power plants. The authors present the results of processing the technological process of recycling ash and slag wastes of TPP in terms of E-networks using mathematical processing in the Simulink application, which displays the device model from the standard blocks available in the program and performs the necessary calculations. 3D models of individual equipment units selected on the basis of mathematical processing calculations in the Simulink application, were created using computer 3D modeling in a graphical editor. A 3D visualization of the technological section of ash and slag waste processing was performed, which allows to clearly show the planned section at the design stage, which, if necessary, will allow to easily make changes to the project.

Summary

Introduction

The problem of utilization of ash and slag wastes (ASW) is relevant. During the operation of the TPP, more than 10% of the processed coal goes to waste. A small part of the ASW is being utilized. In the process of recycling, wall cinder blocks and paving slabs are produced. In Russia, there are more than one hundred thermal power plants, their ash dumps are filled with ASW, and the expansion of such dumps is impossible and has a negative impact on the environment. About thirty million tons of ash and slag are produced each year
