In coal fired boilers, what is the efficiency of CHAIN GRATE compared to FLUIDIZED BED?



about 80-85 % for the gyve grate and 85-90% for the fluidized bed

Leaking back boiler coal fire - not in use as have oil fired CH but how do we remove it, can we do it ourself?

Hi, please alleviate, we have bought a house that has oil fired CH but we also have a coal fire. So far as we know the back boiler is nothing to do with the heating anymore and the pester is all rusty and wet which makes us think the back boiler blow up or is leaking. We want to remove the back boiler root and knock out the fireplace to install a multiburner, but aren't tried if we can do it ourselves, or how to do it. Has anyone any suggestions as to if we can do it and how. Also can we remove the pipes that run down the side of the chimney heart?


canbe done yourself, my suggestion (as a plumber) would be to call in the experts, as it gets very messy and hardc calling

What are some threats to coal-fired boiler power stations going out of business?

There is 23,000 MW of hot air power planned in Texas. Can you guys consider of some other reasons?


Humbug power can't compete with coal and neither can ground based solar unless you've got much more safely a improved energy storage systems then we have now (right now all slew does is reduce the CO2 emissions from fossil sustenance burning and fool people into thinking they can explicate the global warming problem without splitting Uranium).

23 GW of ramble capacity probably means about 5 GW of average power postulated that the wind turbines don't produce power when the coil isn't blowing (which means you'll still have to have about 5 GW of trusty power to back it up and that means fossil fuels (methane as likely as not, coal can't respond fast enough)).

The threat to coal comes from atomic power which unlike wind and ground based solar can absolutely replace coal (notice how France has actually managed to get rid of coal while Germany which is investing a lot in finish up and solar is still building coal plants?). In the subsequent fusion and space solar power will also state look after threats to coal, assuming nuclear fission hasn't already wiped it out when we get them. It wouldn't take much of a carbon tax to flourish coal uncompetitive with nuclear.

Wood and coal fire steam engine boilers if banked right is as good as diesel..should we put them back in use?

With today's technology, the engines could be more valuable
in horsepower and the stacks filtered to environmental standards. Commodities can be moved seashore to coast and
not one drop of imported oil need be occupied. Parts lubrication
can come from home grown sources and drilling domestically.


Yes we should. Thanks for a legitimate question.

Greening the Black of Coal

Some how extensive ideas come across as crazy when you first hear them. I thought that Jim Holm's approximation of recycling coal fired power plants by converting them into nuclear power plants was asinine the first time I encountered it. I now think it is a terrific idea. I wrote about the conviction in May and it recently bubbled up on the "Energy from Thorium" discussion means. I usually don't openly discuss ideas that come up on the scrutiny form, because I think what is said in the discussion form is a off the record conversation. But in the case of converting coal fired power plants into LFTR plants, this is an viewpoint that has been floated by Holm, and which I seconded in May.
Jim and I differ on preferred reactor technology. Jim thinks in terms of Pebble Bed Reactors, I dream in terms of Liquid Fluoride Thorium Reactors. There are several of big reasons why I contrive my solution is better, but I will put off talking about that right now. The big advantage of coal shrub conversion is cost savings. What makes nuclear plants so dear is that you have to build everything from scratch.
Big power plants occupy lots of acquire. You need to build buildings to house the animation producing technology, whether it is coal fired boilers, or nuclear reactors. You also need a erection to house the energy converting technology, the steam or gas turbines and their betrothed generators. Finally you need space to handle the wasteland from your energy production. In the case of coal fired power plans, squander is coal ash. In the case of conventional nuclear plants and Pebble Bed Reactors, destroy is spent fuel. In the case of LFTRs it turns out that there is microscopic waste, and perhaps even no waste at all. At any rate, the LFTR has an uncommonly modest land requirement, and could be easily accommodated in the areas now dedicated to coal fired power plants. So there is no further shortage to purchase new land. The cost of land purchase is thus saved.
Secondly, many of the buildings of a coal...
