Water gas has a lower heat of combustion than coal gas, so the calorific value was often boosted by passing the gas through a heated retort, into which oil was sprayed. كان لغاز الماء حرارة احتراق أقل من حرارة احتراق غاز الفحم، ولزيادة تلك القيمة مُرّر الغاز خلال غرفة ساخنة تعرّض فيها للرّشّ بالغاز.
