Electric Tank Heater Explosions: Risks You Need to Be Aware Of
It is an urgent matter that you immediately review any electric tank heaters for design and installation issues that can lead to explosions and take action at once to avoid an incident.
Combustion Safety Issues Raised by Refractory Blast
During the refractory dryout process, there are many things that can go wrong and cause explosion incidents. Combustion related incidents can occur if flame safety devices or fuel/air ratios are not correct.
Medical University Cured Of Boiler Explosion Ailments
The CEC team brought to an end a long history of explosive "near-misses."
Near Miss - Pilot Stability Evaluation
A boiler was damaged and out of service for more than two weeks due to a delayed main flame ignition.
Flame Detector Site Tube Cautions
There have been a number of cases where we found site tubes (small pipe nipples attached to burners and flame detectors) that have contributed to false flame detector signals.
Light-Off Problems Lead to Three Explosions
The explosions destroyed one boiler and damaged three others, fortunately no injuries were reported. The incidents came after the three boilers experienced trouble lighting-up, had fuel/air ratio, or burner capacity problems.
Fatal Natural Gas Explosion
Natural gas in air reaches its lower explosive limit at a concentration of only 4.3%. Even small leaks, over time, can accumulate in confined areas and support combustion with an ignition source.
Safe and Efficiency Testing = Gas Train Safety
Safe and efficient gas train component testing is everyone's goal. This article discusses the risks associated with various test methods and equipment to make testing easier and more accurate.
Plugged 3-Way Valves Hamper Switch Functionality
CEC engineers have found that automatic valves fail the recommended tightness test at the rate of 10-15% for large size boilers and 2-3% for smaller boilers.
Workplace Emergency Planning from Combustion Safety, Inc.
Whether you work at an industrial plant, school, hospital, or even a large apartment building, your site's facility staff should review their ability to shut off natural gas both outside at the main shut-off and inside at different locations.
Flame Scanner Failure
The life of electronic components and scanners degrades considerably with higher temperatures.
April 17th, 2000 Paint Shop Oven Explosion
A paint shop oven exploded at a major auto manufacturer’s facility. It is our understanding that the oven had been experiencing problems for some time.
Urgent Safety Notice Leaking or Frozen Plug Cock Valves
One of the key findings in our safety inspections is that more than 60% of lubricated plug cocks leak potentially explosive levels of natural gas when in the closed position.
Urgent Safety Notice Gas Train Vent Insect Protection
CEC's Combustion Safety Team has found that many facilities do not have insect screening installed on their gas train regulator vent terminations.
Urgent Safety Notice For Air House Testing
In some cases cracks or voids may exist in the heat exchanger surfaces. This can cause the combustion chamber to become pressurized by the supply air fan.
Hot Water Heater Explodes In Elementary School
Explosions from even simple, relatively obscure, equipment like hot water heaters can be destructive and/or deadly.
