One week after a catastrophic fire at the North Hyde electrical substation plunged the UK’s flagship Heathrow Airport into chaos, questions are mounting about what went wrong—and what the incident reveals about the vulnerabilities in Britain’s aging power infrastructure.
A massive explosion and fire that erupted around 8:20 p.m., on Thursday, March 20, at the North Hyde electrical substation near the international airport caused widespread power outages across West London and prompted the temporary closure of Heathrow Terminals 2 and 4. The airport faced significant disruptions, forced to cancel over 1,300 flights—outages that affected more than 290,000 passengers.
At its peak, the fire knocked out power to an estimated 67,000 households and businesses. The London Metropolitan Police declared a major incident at 12:42 a.m. on March 21. With more than 70 London Fire Brigade personnel on the scene, crews worked to evacuate residents and contain the blaze.
“The fire involved a transformer comprising 25,000 liters of cooling oil fully alight,” said London Fire Brigade Deputy Commissioner Jonathan Smith during a press briefing.…
Coastal California has a big advantage when it comes to growing vegetation – just about any plant, from anywhere will grow and thrive here. Ironically, this is also a disadvantage. Frequently “exotics,” (non-native species) out-compete the native plants and take-over. The exotics, like other unwelcome house guests, have undesirable habits, like dying, drying out and exploding..

The post Rediscovering Fire: Advancements in Gas Turbine Combustion appeared first on POWER Magazine.
Gas power market drivers and a quest for relevance in future decarbonized systems are driving fundamental shifts in gas turbine combustion design approaches.
Combustion lies at the heart of gas turbine technology. It provides the core function of adding heat, through a controlled burn of large amounts of fuel and air, to a gas turbine’s conversion of chemical energy into mechanical energy and, for power generating turbines, electrical energy. In concept, a combustor essentially comprises a fuel injector and a wall to contain the flame. But far from simplistic, the process must achieve a delicate balance of equivalence ratio between the fuel and available oxygen; flame stability; and operational stability to support acceleration and operation of the gas turbine over the entire load of the machine.
Developers have attempted to refine this complex dance for decades, as John Gülen, a fellow at Bechtel Infrastructure & Power Corp. and the American Society of Mechanical Engineers, and the author of several books profiling the evolution and status of gas turbine technology, told POWER.…
