The History Behind Texas Coal Power

Posted on May 23, 2015 by wpadmin

ANDERSON — Straddling a dammed-up creek 20 miles east of College Station squats the Gibbons Creek Steam Electric Station, a massive coal-fired power plant supplying the city-owned utilities of Denton, Bryan, Garland and Greenville.

In the plant, a boiler is suspended from a steel beam like a glowing bee’s nest hanging from a giant tree limb. A conveyor feeds the boiler finely ground coal, fueling a fireball hotter than flowing lava. . . The control room on top of the plant is aglow with computer screens where workers in overalls press buttons to control feeders, fans and flow rates, and monitor the behavior of the fireball inside the boiler. Good behavior is determined by how much and what form of sulfur, carbon, mercury, nitrogen, particulates and other contaminates the burning coal produces.

“All this is just a giant chemistry experiment,” said Jan Horbaczewski.

Landfill Gas and Biogas Symposium

The Landfill Gas and Biogas Symposium March 16-19, 2015 in New Orleans will give biomass managers a chance to assess their system and look for ways to increase efficiency using successful case studies. “At a DTE Biomass Energy site consisting of (2) CAT 3520 engines, a series of incremental improvements cascaded on each other, leading to a drop in plant operating costs of over 35% from 2010 to 2013 and a plant on-stream rate improvement from 93.2% to 96.6%. What appear to be common sense applications of problem solving proved themselves to be game changers…”

IPCC Climate Change Report makes a strong case for change

Posted on November 14, 2014 by wpadmin

The Intergovernmental Panel on Climate Change Nov. 2 issued its Synthesis Report – a combination three IPCC Working Group reports, which IPCC says are “the most comprehensive assessment of climate change ever undertaken.”

The report is the joint effort of 800 lead authors, almost 1,000 more supporting authors and a combination of 30,000 scientific papers. The report “distills and integrates the findings” and provides information critically important for policymakers, IPCC says.

But David Malakoff poses the pertinent question in his article in Science magazine: “whether the new IPCC report can help overcome the political and economic obstacles that have blocked major movement of reducing emissions.”

Vexed by Earthquakes, Texas Calls in a Scientist

“Surely the seismologist – this man of science, highly educated and blessed with good ol’ boy roots in West Texas – must know what he’s getting himself into. The Texas oil boom is the envy of the nation, a source of strength in uncertain geopolitical times. Smart people are moving in from the coasts. Investors are getting rich. Even a high school dropout can make decent money behind the wheel of a truck. Life is good…”

Students from Russia, U.S., Norway, Germany, Italy, China and U.K. arrived this week in Norilsk, Russia where they will spend two weeks in a field school to assess the effects of permafrost thaw on Russian urban infrastructure.

The student researchers will conduct permafrost research in the field as well as meet with representatives of the Norilsk-Nickel mining company and of local production plants and geological, planning, social and migration services to form a science-based dialogue about problems and solutions.

When spring 2015 approaches, sun spilling the landscape will find a group of scientists adrift at sea on “RV Lance” – once a top-of-the-line seal hunting boat, now turned research vessel.

On board the ship, an international collection of researchers will watch up-close as the arctic wakes, with instruments tuned not only to wildlife but to the most important creature of them all – the sea ice.
