History of the East London Line
HISTORY OF THE EAST LONDON LINE – FROM BRUNEL’S THAMES TUNNEL TO THE LONDON OVERGROUND by Oliver Green A report of the LURS meeting at All Souls Club House on 11 October 2011 Oliver worked at the London Transport Museum for many years and was one of the team who set up the Covent Garden museum in 1980. He left in 1989 to continue his museum career in Colchester, Poole and Buckinghamshire before returning to LTM in 2001 to work on its recent major refurbishment and redisplay in the role of Head Curator. He retired from this post in 2009 but has been granted an honorary Research Fellowship and continues to assist the museum in various projects. He is currently working with LTM colleagues on a new history of the Underground which will be published by Penguin in October 2012 as part of LU’s 150th anniversary celebrations for the opening of the Met [Bishops Road to Farringdon Street 10 January 1863.] The early 1800s saw various schemes to tunnel under the River Thames, including one begun in 1807 by Richard Trevithick which was abandoned two years later when the workings were flooded. This was started at Rotherhithe, close to the site later chosen by Marc Isambard Brunel for his Thames Tunnel. In 1818, inspired by the boring technique of shipworms he had studied while working at Chatham Dockyard, Brunel patented a revolutionary method of digging through soft ground using a rectangular shield. His giant iron shield was divided into 12 independently moveable protective frames, each large enough for a miner to work in. -
Thesis a Modeling Tool for Household Biogas Burner
THESIS A MODELING TOOL FOR HOUSEHOLD BIOGAS BURNER FLAME PORT DESIGN Submitted by Thomas J. Decker Department of Mechanical Engineering In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Summer 2017 Master’s Committee: Advisor: Thomas Bradley Jason Prapas Sybil Sharvelle Copyright by Thomas J Decker 2017 All Rights Reserved ABSTRACT A MODELING TOOL FOR HOUSEHOLD BIOGAS BURNER FLAME PORT DESIGN Anaerobic digestion is a well-known and potentially beneficial process for rural communities in emerging markets, providing the opportunity to generate usable gaseous fuel from agricultural waste. With recent developments in low-cost digestion technology, communities across the world are gaining affordable access to the benefits of anaerobic digestion derived biogas. For example, biogas can displace conventional cooking fuels such as biomass (wood, charcoal, dung) and Liquefied Petroleum Gas (LPG), effectively reducing harmful emissions and fuel cost respectively. To support the ongoing scaling effort of biogas in rural communities, this study has developed and tested a design tool aimed at optimizing flame port geometry for household biogas- fired burners. The tool consists of a multi-component simulation that incorporates three- dimensional CAD designs with simulated chemical kinetics and computational fluid dynamics. An array of circular and rectangular port designs was developed for a widely available biogas stove (called the Lotus) as part of this study. These port designs were created through guidance from previous studies found in the literature. The three highest performing designs identified by the tool were manufactured and tested experimentally to validate tool output and to compare against the original port geometry. -
Biogas Stove Design: a Short Course
Biogas Stove Design A short course Dr David Fulford Kingdom Bioenergy Ltd Originally written August 1996 Used in MSc Course on “Renewable Energy and the Environment” at the University of Reading, UK for an Advanced Biomass Module. Design Equations for a Gas Burner The force which drives the gas and air into the burner is the pressure of gas in the pipeline. The key equation that relates gas pressure to flow is Bernoulli’s theorem (assuming incompressible flow): p v2 + +z = constant ρ 2g where: p is the gas pressure (N m –2), ρ is the gas density (kg m –3), v is the gas velocity (m s –1), g is the acceleration due to gravity (9.81 m s –2) and z is head (m). For a gas, head ( z) can be ignored. Bernoulli’s theorem essentially states that for an ideal gas flow, the potential energy due to the pressure, plus the kinetic energy due to the velocity of the flow is constant In practice, with gas flowing through a pipe, Bernoulli’s theorem must be modified. An extra term must be added to allow for energy loss due to friction in the pipe: p v2 + −f ()losses = constant . ρ 2g Using compressible flow theory, flow though a nozzle of area A is: γ p γ ()γ − γ m = C ρ A 2 0 r2 (1− r 1 ) & d 0 γ − ρ 1 0 ρ where p0 and 0 are the pressure and density of the gas upstream of the = nozzle and r p1 p0 , where p1 is the pressure downstream of the nozzle. -

A Wood-Gas Stove for Developing Countries T
A WOOD-GAS STOVE FOR DEVELOPING COUNTRIES T. B. Reed and Ronal Larson The Biomass Energy Foundation, Golden, CO., USA ABSTRACT Through the millennia wood stoves for cooking have been notoriously inefficient and slow. Electricity, gas or liquid fuels are preferred for cooking - when they can be obtained. In the last few decades a number of improvements have been made in woodstoves, but still the improved wood stoves are difficult to control and manufacture and are often not accepted by the cook. Gasification of wood (or other biomass) offers the possibility of cleaner, better controlled gas cooking for developing countries. In this paper we describe a wood-gas stove based on a new, simplified wood gasifier. It offers the advantages of “cooking with gas” while using a wide variety of biomass fuels. Gas for the stove is generated using the “inverted downdraft gasifier” principle. In one mode of operation it also produces 20-25% charcoal (dry basis). The stove operates using natural convection only. It achieves clean “blue flame” combustion using an “air wick” that optimizes draft and stabilizes the flame position. The emissions from the close coupled gasifier-burner are quite low and the stove can be operated indoors. Keywords: inverted downdraft gasifier, domestic cooking stove, natural draft *Presented at the “Developments in Thermochemical Biomass Conversion” Conference, Banff, Canada, 20-24 May, 1996. 1 A WOOD-GAS STOVE FOR DEVELOPING COUNTRIES T.

INTRODUCTION The present investigation is the beginning of an attempt to supply a long-felt need of an accurate knov/ledge of the spectral energy distribution, of some standard sources of Hght, in the visible and in the ultra-violet parts of the spectrum. The problem is a difficult one and heretofore has never been given thorough attention. Once the spectral energy distribution of a standard source of illumination is accurately known, it is possible to obtain the spectral energy distribution of other weaker sources of radia- tion by indirect methods, such as by spectrophotography or spectrophotometry. The standard sources which are the most easily reproduced are probably well seasoned incandescent lamps 243 244 Bulletin of the Bureau of Standards [Voi. -

Looking By Donald Dewey ER G This is where Humphrey Bogart delivers the classic line to Ingrid Bergman in Casablanca (1942). at You, Kid GRAN 30 SCANDINAVIAN REVIEW SCANDINAVIAN REVIEW 31 Ingrid Bergman at 26 HAT IS THERE LEFT TO SAY ABOUT INGRID BERGMAN? Journalists and biographers and film historians have been dipping W into Bergman’s life (1915–1982) so relentlessly for so long that it is easy to forget that it wasn’t always in the public domain. The woman’s career, off and on screen, started being dissected so minutely so many decades ago that just about the only survivors from all those labors are her children and a hand- ful of actors from the already-41-year-old Murder on the Orient Express. In short, and though many of us are loath to admit it, the world of Ingrid Bergman seems to have warp-sped away from us to distances we might not have thought possible. It may not be as remote as Planet Garbo, but it is still out there, back in that century they used to call the 20th with an air of self-satisfaction making it sound like the tiniest of steps before infinity. (“My God, man, it’s the 20th century!”) There is, of course, the record of her many performances—filmed, kinescoped, taped, digitized, hologrammed, whatever technical development preserves them next.
