The present invention provides a process for burning coal instead of oil comprising the stages of coal gasification, gas combustion and optionally gas purification, utilization of residual heat of flue gas and flue gas discharge. The present invention further provides an apparatus for burning coal instead of oil. By present invention, the fuel cost for an oil-burning apparatus can be reduced by about four-fifths, so the resources of oil and natural gas can be saved either. Furthermore, the present invention has the advantages such as good reliability, high heat efficiency, high level of automation, high return on investment and good environmental benefits.
