Pandan a pwosè pwodiksyon angrè an, se yon gwo gwo dezè chalè pou ka refè, espesyalman nan chabon founo gazéification. Pa installation yon chodyè chalè tounen yon dezè pou sòti anba yon maladi chalè a nan chemine a, yonn kapab ankò bezwen yon chabon dife chodyè pou pase jiska en. Sou dis syèk pase, pi plis angrè konpayi yo te chanje metòd gaz ap fè yo soti nan yon tradisyonèl ti kal mare kabann yon kabann laj ekay craquage (nan mitan gwo pwesyon chabon gazéification).

During the the fertilizer production process, there is a huge potential waste heat to be recovered, especially in the coal gasification furnace. By installing a waste heat boiler to recover the heat from the furnace, one can no longer need a coal burning boiler for steam output. Over the past decade, more and more fertilizer plants have switched their gas-making method from a traditional small scale fixed bed to a large scale fluidized bed (mid-high pressure coal gasification).
