on the test data of a 300MWe coalfired boiler, the simulation results of BP model were given, and Analyzed the accuracy of the model. Section III introduced NSGAII algorithm and steps involved in implementation to the multiobjective optimization of a coalfired boiler combustion problem. Section IV performed application of
Optimisation of cutting cycles in conventional underground coal sections to improve productivity serves as an area of study that deals with the utilisation of the machines in conventional underground coal sections. Utilisation of machines focuses on reducing the time that machines spend idle and increasing the amount of time during shifts that machines are actively contributing to production. This can be .
From the mine to the plant. Coal handling systems are an integral part of a complete material flow and quality management system (Figure 1). In recent years, the main focus was on the optimisation of single parts of this system, such as mine planning or advanced automation solutions.

Prior to optimization of primary airflow it is prudent to perform clean air balancing. This will insure minimum fuel line velocities in all fuel lines must exceed 3,300 feet/minute (Fpm). Fuel line velocities above 3,300 Fpm are to insure coal entrainment in primary air. • Air velocities below 3,000 Fpm allow coal to fall out, accumulate or
A framework is proposed for integration of unit modeling, process synthesis, analysis, optimization, and process design of coal gasificationbased energy and chemical processes. The conceptual models of these processes are built by the modeling and synthesis blocks in the framework, which are the bases of analysis and optimization.

operation optimization [1]. In this paper. the optimization is at the operation level. In this sense, the synthesis and design of a system are known and fixed. The conventional thermodynamic optimization process of an energygenerating system usually focuses on the energy saving or exergy saving. This kind of optimization has many drawbacks: (1)
coal quality and blending ratios on the fuel cost in a thermal power plant. 2 PROCEDURE FOR CALCULATING FUEL COST For the purpose of optimizing the fuel cost a sensitivity analysis of all the parameters was carried out. Fig2 shows the cost optimization flow chart. The work was divided into five major parts, namely Fig2: Cost optimization flow chart i.
The developed criteria allow for more reliable and trustworthy optimization, thus, four additional aspects of clean power generation from coal are investigated. First, design and optimization of pressurized oxycoal combustion at the systemslevel is performed while utilizing a direct contact separation column (DCSC) instead of a surface heat ...
Automated multiobjective optimization proposes a reliable and promising method to integrate CAD and CAE tools with optimization methods in an automated fashion to perform faster, more accurate, more efficient and more costeffective designs in the field of coal combustion and gasification.
This paper presents the design optimization for the Xianglushan tungsten mine using the room and pillar mining technique. The influence of pillar height, pillar length, pillar width, room length and room width on the stability of room and pillars was examined through .
The abrasiveness of a coal is a function of the mineral matter characteristics. An empirical expression was developed by Raask which allows for comparative analysis of coals and is presented by the equation:
This paper presents the design optimization for the Xianglushan tungsten mine using the room and pillar mining technique. The influence of pillar height, pillar length, pillar width, room length and room width on the stability of room and pillars was examined through analyses using the orthogonal experimental design method. The pillar and room sizes were identified as the most critical factors.
Solving LargeScale Optimization Problems with MATLAB: A Hydroelectric Flow Example By Seth DeLand, MathWorks Setting up and solving a large optimization problem for portfolio optimization, constrained data fitting, parameter estimation, or other applications can be a challenging task.
The storage capacity of a coal matrix can be considered as a economic resource; however the coal matrix permeability is very low. The coal fracture system, particularly the cleat system, provides media for fluid flow in the coal system. The cleat system contributes to overall formation permeability.

From a systems perspective, optimizing an oxyfired coal plant with carbon capture is very challenging, as the subsystems of the power plant are tightly integrated. For example, adjusting the flue gas recycle rate will impact the air separation unit (ASU), boiler, steam cycle and CO2 process unit (CPU) – essentially the entire power plant.
