Heat efficiency of steam injection boiler is generally low in oilfields. Flue heat loss is the main factor affecting boiler heat efficiency and depends on fluegas temperature and volume.
The calandria arrangement in the furnace floor fluegas channel that is formed by the ondol pier bricks with circular sections greatly lowers the local resistance loss of fluegas.
