  • Impact of Fuel Variability and Operating Parameters on Biomass Boiler Performance
    Impact of Fuel Variability and Operating Parameters on Biomass Boiler Performance by Nazanin Abbas Nejad Orang A thesis submitted in conformity with the requirements for the degree of Doctorate of Philosophy Chemical Engineering and Applied Science University of Toronto © Copyright by Nazanin Abbas Nejad Orang 2019 Impact of Fuel Variability and Operating Parameters on Biomass Boiler Performance Nazanin Abbas Nejad Orang Doctor of Philosophy Department of Chemical Engineering and Applied Chemistry University of Toronto 2019 Abstract Biomass boilers provide up to one-third of the energy requirement in pulp and paper mills by burning hog fuel, which is a mixture of wood-waste available at the mill site. The quality of this fuel varies significantly depending on its source and storage conditions. This fuel variability often causes biomass boiler operation to be unstable and unpredictable. This study consists of two parts: the first part investigates the impact of fuel variability on combustion and develops means for mitigating these impacts to achieve stable boiler operation. The second part identifies the most influential parameter in boiler operation using multivariate analysis, and develops a predictive statistical model for optimization of biomass boiler thermal performance. In the first part, wood species are differentiated by their initial particle density. For all wood species examined, particle density decreases throughout the combustion process but at different rates depending on the combustion stage. During the devolatilization stage, the density decreases significantly as a result of rapid mass loss. This sharp decrease causes particles to be light enough to be entrained and/or be lifted off from the grate by the flue gas.

Cotton, Arthur Freedman Associates, Inc. and Orin Hollander, Holland Technologies, Inc. This is part two of a three-part series on boilers. In part one, the authors discussed boiler design and classification. Part two will discuss boiler components, and part three will describe the various chemistries used in boiler water treatment. Boiler Components The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump. In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions. Water sample points may exist at a number of places. Most typically the condensate, deaerator outlet, feedwater (often the economizer inlet), boiler, saturated steam and superheated steam will have sample points.

  • Watertube Boilers
    Watertube Boilers Learning Outcome When you complete this module you will be able to: Describe various watertube boiler designs, including large generating units. Learning Objectives Here is what you will be able to do when you complete each objective: 1. Describe early designs and construction of watertube boilers. 2. Sketch and describe the design and construction of packaged watertube boilers. 3. Describe the design, construction, and components of large scale steam generating units. 1 BLRS 6016 INTRODUCTION The watertube boiler differs from the firetube design in that the tubes contain water rather than combustion gases. In the watertube boiler, the combustion gases travel over the outside surfaces of the tubes and transfer their heat to the water within the tubes. WATERTUBE BOILERS Longitudinal Straight Tube Boilers Fig. 1 illustrates one of the earliest straight tube boilers. The drum runs longitudinally in relation to the tubes. The straight inclined tubes run between vertical headers at the front and rear of the drum; these headers are connected to the drum at their top ends. The combustion gases make three passes across the tubes as indicated by the arrows in Fig. 1. AL_4_0_4.mov A AL4_fig1.gif Figure 1 Straight Tube Design (Longitudinal) The water circulates from the water space of the drum down the rear header, up the inclined tubes (at an angle of 15° to the steam drum), to the front header, and then back up to the drum. 2 BLRS 6016 Figure 2 AL4_fig2.gif Babcock & Wilcox Boiler (1877) The early boiler shown in Fig. 2 had an elaborate setting.

  • Boiler a Boiler Is a Closed Vessel in Which Water Or Other Fluid Is Heated
    Boiler A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. (In North America the term "furnace" is normally used if the purpose is not actually to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation,cooking, and sanitation. Contents • 1 Materials • 2 Energy • 3 Configurations • 4 Safety • 5 Superheated steam boilers 5.1 Supercritical steam generator • 6 Accessories 6.1 Boiler fittings and accessories 6.2 Steam accessories 6.3 Combustion accessories 6.4 Other essential items 6.5 Gas safe check • 7 Draught • 8 See also • 9 References • 10 Further reading Materials The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking. However, ferritic stainless steel is often used in superheater sections that will not be exposed to boiling water, and electrically-heated stainless steel shell boilers are allowed under the European "Pressure Equipment Directive" for production of steam for sterilizers and disinfectors. In live steam models, copper or brass is often used because it is more easily fabricated in smaller size boilers. Historically, copper was often used for fireboxes(particularly for steam locomotives), because of its better formability and higher thermal conductivity; however, in more recent times, the high price of copper often makes this an uneconomic choice and cheaper substitutes (such as steel) are used instead.
