Chain grate boilers are mainly applied in the industrial boilers in China during the recent 30 years

and in the meantime the rational furnace arch configurations play an important role in ensuring the boilers combustion reliably and efficiently. Therefore

in accordance with the present situation of the coal used in the industrial boilers in our country

a special furnace arch design method isoffered in thispaper

which ascertainsthe furnace arch configuration through the coal combustion characteristic analysisso that the boilermanufacturersand usersmayreferwhile theydesign and retrofit furnace arch.
