Blowout Preventers (BOPs) are a configuration of valves and piping used to ensure pressure control of a well. A typical BOP stack might consist of one to six ram-type preventers and one or two annular-type preventers. A typical configuration has the ram preventers on the bottom and the annular preventers at the top. The configuration of the stack preventers is optimized to provide maximum pressure control and safety in the event of a well control incident. It is common to have an annular preventer or two on top of the stack since annulars can be closed over a wide range of tubular sizes and the openhole, but annular preventers are typically not rated for pressures as high as ram preventers. The BOP stack also includes various spools, adapters and piping connections to permit the circulation of wellbore fluids under pressure in the event of a well control incident.

The spill began on April 20. The oil spill started when there was an abnormal pressure change, interpreted as a gas kick, which they could not control, and a blow out resulted. Crude oil poured on the rig floor and caught on fire. The intense heat from the burning of crude coming onto the rig floor and stored oil on the rig caused the rig to collapse and sink. The gas kick means gas had entered either the drill pipe or the marine riser. The weight of the fluids in the hole (usually drilling mud) should always be sufficient to prevent influx of reservoir gas and oil. It was this underweighting or lost fluids in the wellbore, not the rig catching fire and sinking that caused blow out and subsequent oil spill. A poor cementing of the production casing is a possibility. There is an investigation ongoing, which hopefully will have more details. It is not known why the blow out preventers (BOP) failed to actuate. BP has stated that it can, after the Maconda well is capped, remove the BOP stack for investigation. This might be several months away.
Flue gas is the gas that is emitted from a combustion process within a building or industrial facility, while stack gas refers to the mixture of gases emitted from a chimney or stack. In general, flue gas is the specific type of gas that is produced from a specific process, while stack gas is the broader term that encompasses all gases emitted from a stack or chimney.

Before you fix something you've got to understand the well. The oil is leaking from a wellbore, which is really a pipe that allows oil to flow from an underground deposit at about 13,000 ft to the ocean floor. The oil at present is coming up through the pipe, then passing through the blow out preventer (BOP) stack and escaping through the riser. A cement seal is in place between the casing pipe and formation at least from the ocean floor to part way down the last string of pipe. You don't want to destroy this seal. I guess the bomb idea is to destroy the BOP and wellhead. Oil would continue to flow without the stack, but the bomb would shake the earth so much that you will break down the cement seal between the pipe and formation, fractured some of rock, and oil will come out from both the pipe and the behind the pipe. I imagine there would be a pile of rubble subsea, from which the gas would make a worm hole followed by easy passage of oil.
Smoke, hot air, and various pollutants are typically emitted from a power plant stack. These byproducts are released as a result of burning fuels such as coal, oil, or natural gas to generate electricity.

A bad or clogged stack relay i have found bad oil will cause the stack relay to clogged
About the most common application of flue gas is as a heat source. Recall that flue gas is the stack gas from plants fired with combustibles (coal, oil, gas, biomass, etc.), and it exhausts into the atmosphere. We spend a lot of money monitoring stack gas to keep the combustion process as tightly controlled as possible. That minimized emissions. The heat in the stack gas can be used to heat water or the like, and the preheated water can then be fed back into the boilers to create the steam that drives the turbines that generate electric power (which is one example, but a common one). The heating of the (boiler) feedwater with the flue gas increases the efficiency of the whole operation. It's classic steam cycle power generation, and the preheating of feedwater within the stack (by the flue gas) is a time-proven tactic to reduce costs.

The BOP or blow out preventer is used to shut in a well when all other means have failed. It shuts in a well by either cutting through or crimping the production tubing or drill pipe in the well. As was clearly shown in the 2010 Macondo well blow out, the blow out preventer can not close in the well in all cases.
