in ammonia plant there is synthesis waste heat boiler vertical type is used .why?

why whb philosophy vertical instead of horizontal. i want internaldiagram
If you are asking why a waste heat boiler is toughened, it is to capture all of the energy produced in the cycle of making the ammonia. There is residual heat towards the end of the cycle, and this heat can be used to generate steam, which can be reach-me-down to drive a turbine or provide heat in another location.

What type of boiler is suitable for a flat with no external wall access and no waste pipe connection.?
Jun 16, 2007 by raysheauk | Posted in Maintenance & Repairs
I have a hot fizzy water be illogical boiler and a hot air heating boiler.I wish to put back both with one boiler and install central heating.Both of my boilers are in a cuboard in my living leeway, with a service duct going up the building and no access for waste store pipe,I live on the 8 floor.
New fan flued boilers only need a 100mm diameter opening through an external wall. I'm sure you must have one as I cannot envision a flat with no windows. Consult a heating plot they should give you a recommendation and a quote free of charge.

What is the most efficient way to convert heat to electricity ?
Sep 29, 2008 by Paul H | Posted in Engineering
Have a multitude of heat sources available geothermal and waste wood being the sheer ones, considering installing a industrial wood boiler, turbine and generator. is this attainable for a system running at about 350btu's
Heat alone is not enough, you also constraint a cold heat sink.
But geothermal heat is in use as a power beginning, as is burning waste wood.
350 BTU per what? per second, per hour, per year?
per imperfect, that is 370 kW, a large amount of power for a individual habitation.

For condos in a 6-unit bldg, is individual forced air heat cheaper than steam radiators on a common boiler?
Dec 27, 2006 by chi_chica | Posted in Maintenance & Repairs
I have infer from that water-based radiators are much more efficient and hospitable than forced air, but I can't find comparisons for steam radiators. With steam, you can not hold back the temperature of individual radiators (so some rooms are fantastic overheated while others are freezing) and boilers are apparently often oversized because they were installed/sized before the sham of double-hung windows and other weather proofing devices resulting in a lot of waste. In beyond, all of the people in our building keep different hours, which means that many of us are paying for heat we do not use and sometimes do not lust after (like at night). Our heating bill is enormous--in the neighborhood of $300-$400 a month per part for a 1200s ft apt. Also, none of us have central air, which would be a great benefit to having phoney air heat (use the same ducts for a/c). I believe central AC would also be more efficient. Does anyone recognize what makes the most financial sense or where to look for answers?
Get some quotes from an HVAC train. Todays furnaces are much more efficient than even those of 10 years ago, let alone steam heat.
"Glad" heating does not have to be the old radiators on the walls anymore.... you can have rapturous heat lines installed in floors, or ceilings now, or, there are even some modest units that look like electric baseboard heaters.
Bottom activity for myself?? If its a 'condo'... I own it... Id rather have stilted air than the old radiators any day, heheheh.
Check with your electric utility also, when getting prices on new systems... you can sometimes get rebates, or credits, by switching over to stimulating furnaces.
First thing I would do, would be to get some quotes coming in by the resident HVAC dealers.
Good Luck

Coals vary a lot in their energy content. The energy released by the burning of coal is typically between 23 a?
Dec 23, 2008 by Efrat S | Posted in Physics
Coals shift a lot in their energy content. The energy released by the seething of coal is typically between 23 and 33 Mega Joules per kg of coal. The power workshop above uses coal rated at 23.9 MJ/kg to heat the boilers. Some of that heat is converted to electrical vitality, but most is waste heat discharged into the environment. Assume that it takes about 2.20 kg of oxygen to blacken 1 kg of coal (The actual amount varies with the type coal). Find the whole mass of the reagents used in operating for 30 days
A power seed burns coal and generates an average of 650.0 Megawatts (MW) of electrical power while discharging 1079.00 MW as waste heat. Find the amount electrical energy generated by the plant in a 30-day days.
