He does seems like it. I think he and his nearby buddy were fishing. I can see what looks like a fishing pole next to him as he seems to be trying to put bait on his line or something.

Who rolls up the bottom of his shirt just to bait a hook?

Who rolls up the bottom of their shirt to take a leak?

It's quite common practice for men to roll up their shirts to expose their bellies and lower back to try to cool down when hot in China.

Guy could be taking a leak, or just airing his belly to stay cool or both. But what does it matter anyways?

I guarantee you, there's no fish at that place

You will be surprise, who knows there's always a flounder or two hanging around at the piers.

The cycle is tangential to the issue. The issue is the rate at which each boiler can generate thermal energy.

The rate at which air is supplied to the boiler determines the rate at which fuel can be burned, which in turn determines the amount of energy available to generate, heat and pressurize the steam.

The production rate, pressure and temperature of the steam determines both how much power is supplied to the turbine, and the efficiency with which the turbine can extract that power to turn the shaft.

When other factors are held constant, increasing the rate at which the boiler ingest air increases the rate at combustion can occur, which increases the thermal energy added to the steam, and increase the energy that can be recovered by the turbine for powering the shafts.

Obviously it assumes the entire system had been designed to process the amount of steam generated at the perspective air intake rate and combustion condition.

So the conclusion is increase air does make boiler smaller or not? I thought you try to refute my claim that increase air will result in smaller island?
Many boiler run on natural circulation depending on venturi effect but less efficient !

Forced draft won't make the exhaust any smaller. The purpose of forced draft is to increase the amount of air fed into the boiler furnace. This allows fuel to be burned at a higher rate, thus allowing more steam under higher pressure and temperature to be generated in smaller and more compact boilers. But burning more fuel hotter in the presence of more oxygen increases the amount of exhaust gas. So it doesn't do anything to reduce the size of the exhaust.

Now you say in order to increase combustion you need more air that mean the need to add forced draft fan!

More air mean more volume rate of intake inside the furnace with constant stack diameter it also more speed to exhaust gas!

Which was my contention in the first place. Increase combustion alone will not improve the efficiency of the boiler need to add extra equipment

I see they are now making, with this pic, good progress on installing the Type 382 Sea Eagle 3-D Radar and other sensors on the main mast there.
