Control Of Fuel Combustion In Boilers

This book examines key issues in improving the efficiency of small and medium power boiler units by adding control systems for the fuel combustion process. The original models, algorithms, software and hardware of the system developed for controlling the fuel combustion process are presented. In turn, the book presents a methodology for assessing the influence of climatic factors on the combustion process, and proposes new methods for measuring the thermophysical characteristics, which require taking into account the concentration of oxygen in the air. The system developed here was implemented on a boiler of the NIISTU-5 type, which is widely used for heat power engineering in Ukraine and other Eastern European countries. Given its scope, the book offers a valuable asset for researchers and engineers, as well as lecturers and graduate students at higher education institutions dealing with heat engineering equipment.

Establishes minimum requirements for the functional design specification of combustion control systems for drum-type, fossil-fueled power plant boilers. Addresses combustion control subsystems in boilers with steaming capacities of 200,000 lb/hr (25 kg/s) or greater, including (but not limited to) furnace pressure control; air flow control; & fuel flow control when firing coal, oil, gas, or combinations thereof.

This book is for anyone who works with boilers: utilities managers, power plant managers, control systems engineers, maintenance technicians or operators. The information deals primarily with water tube boilers with Induced Draft (ID) and Forced Draft (FD) fan(s) or boilers containing only FD fans. It can also apply to any fuel-fired steam generator. Other books on boiler control have been published; however, they do not cover engineering details on control systems and the setup of the various control functions. Boiler Control Systems Engineering provides specific examples of boiler control including configuration and tuning, valve sizing, and transmitter specifications. This expanded and updated second edition includes drum level compensation equations, additional P&ID drawings and examples of permissive startup and tripping logic for gas, oil, and coal fired boilers. It also covers different control schemes for furnace draft control. NFPA 85 Code 2007 control system requirements are included, with illustrated examples of coal fired boilers, as well as information on the latest ISA-77 series of standards.

Depending on what part of the country that you reside in, gas-burning heating systems can be either an absolute necessity or a rarity. For those that maintain, service and install gas heating systems or those just looking for a more in-depth source of accurate information, this modular training program focuses on furnaces and boilers that burn natural gas or LP. The combustion of gas to generate heat can be dangerous and should be thoroughly understood by HVAC technicians. This program covers many facets of gas heating including: combustion, system components and controls, heating sequences, installation, and troubleshooting. Through advancements in technology, modern heating systems have become far more efficient than their predecessors. Integrated circuit boards and electronic ignition systems have replaced the mechanical controls and manually lit pilots of older systems. Today, technicians may encounter furnaces or boilers that are older than they are, complex high-efficient systems, or anything in between. It is critical that they have a working knowledge of all these systems. This manual provides students and practicing technicians with the information and knowledge necessary to safely work on systems that incorporate gas combustion to provide heat. The information to service, maintain, and install these systems is also presented in an easy-to-understand format. The manual is full of color images and diagrams and includes end-of-chapter worksheets. Gas Heating was written to be a primary text that focuses specifically on gas-burning heating systems which can be used as a stand-alone text or a supplement to your current text book.

Now you can use the answerbook that has helped thousands of companies slash their operating costs by eliminating wasteful inefficiencies in their boiler plants. The fully illustrated text brings you testing and flame evaluation techniques, steps for improving control of excess air flow, easy-to-follow boiler efficiency calculation methods, guidelines for optimizing boiler maintenance procedures, and a wealth of other useful details for improving combustion efficiency. The expanded and updated fourth edition includes chapters covering tuning of industrial boilers, as well as current approaches for NO[subscript x] control. Also covered are techniques for improving steam distribution system efficiencies, strategies for reducing waste heat energy losses in stack gasses and expelled waste water, and an examination of specific boiler characteristics and components, including fuel types, firing methods and steam demands. Loaded with time-saving checklists, illustrations and case histories, this book will provide an invaluable resource for anyone involved in efforts to cut fuel consumption and improve steam generation system productivity.

Boiler Control Systems provides definitive information on the design, implementation, maintenance, & operation of large-scale control systems for boilers. It forms a bridge between the disciplines of the electronics engineer & the plant engineer to enable each to understand the issues involved. The book deals first with plant engineering issues, then moves on to consider control systems themselves, & finally a wide range of practical considerations such as commercial aspects, measurements & site considerations. Boiler Control Systems will be of immense use to boiler designers, systems engineers in process control, plant owners, operators, & maintenance staff.
