I think the answer you are looking for may be that water condenses at "normal" temperatures while CO2 does so only at unusually low temperatures. The 32F reference temperature for industrial combustion calculations is way above CO2 condensing temperatures, so the latent heat of CO2 can be...
Burning woodwaste is better than burning fossil fuels if the waste was going to rot otherwise (such as when landfilled). That is a no-brainer.
Cutting down trees to produce power is just as stupid as growing corn to produce methanol. It takes government grants to make it economically feasible...
Can't you set-up an extraction fan & hood near the source so as to evacuate say 10% more than the volume of steam you are generating. It would be better than mixing all that steam with the ambiant air before exhausting it outside.
What governs the evaporation rate is the heat from the steam. While blowing air might lower the water temperature, it will not increase the evaporation rate significantly. you still need to provide the heat via the steam coil.
If the incoming water is very hot, blowing air will get the water...
I wouldn't expect to run a boiler without the FD fan running. You will get away without the FD fan for a low load but at some point you will be smoking up the boilerroom. Balanced units are not designed for pressurised furnace operation. If the smoke doesn't bother you, hot spots on the external...
A PC boiler is designed suspension burning while biomass is usually burned on a grate or in a fluidised bed. You are looking at a major conversion and a sizable expenditure but there is no reason it can't be considered.
I would investigate two avenues:
1) thoroughly dry (with the flue gases)...
One could consider a heat pump on a warm stream to produce a hot stream for space or water heating and/or to run an ammonia chiller. It needs power but lowers the energy cost.
I suspect it wouldn't be cost effective.
The only reason to evaluate the loss through a failed steam trap would be to justify (to your stingy boss) spending the money to replace it. My tip is: spend the money on the new trap, not on the engineering.
Cheers
"Indeed, if I consider the water saturation pressure at air temperature, this is higher than ambient pressure.
Does it make sense to define a relative humidity in this conditions ?"
NO.
There can be an infinite quantity of water per pound of dry air because the temperature is above the...
I would venture YES but due consideration must be given to the question "a percentage of what".
For example: I would say that comparing the ratio of final temperatures (actual / calculated) is quite missleading. The ratio of actual / calculated heat transfer coefficient (or associated R value)...
I would put my concerns in writing and send them registered mail to your ex employer. This way you cover yourself by passing the responsability on and you can't be accused of trying to harm anyone's reputation.
