CO2 emission estimation - coal-fired boiler
CO2 emission estimation - coal-fired boiler
(OP)
Does anyone know an experimental formula to calculate the emission quantity if we only know heat value of coal?

RE: CO2 emission estimation - coal-fired boiler
I'm having some home computer problems so it might be tomorrow until I can post anything, if that book has it.
RE: CO2 emission estimation - coal-fired boiler
is just one link using Google and 'coal heating value carbon content'. Suggest you do some searching, you should be able to get a reasonable estimate though if you want a precise answer, you'll need to do an ultimate analyses on your coal.

This is just a rough estimate.

its not pr. 12 g of coal burned but pr. 12 g of "difference between coal and ash" produces 44 g of CO2

Perry VI fig 9-1, shows the fixed C % of different coals and their thermal values. From the graph we may see that there is no linear relationship between them. For example, there is a maximum of some 15,000 Btu/lb for bituminous coal having about 70% carbon, while anthracite with some 90% C has a reported value of 14,000 Btu/lb, both with the same degree of moisture. This means that volatile material in bituminous coal contributes more to heat release than an equivalent fixed carbon % in anthracite.
Volatile material is that part of coal liberated as gases or vapours from the thermal decomposition of carbon-combined substances when heated in the absence of air.

The 5th edition (student edition if that makes any difference) has it in chapter 9 but in both cases, it's easy to find the section.
