A pulverized coal burner for a furnace adapted to be used in conjunction with a pulverizer which reduces coal to approximately 40 microns size in the presence of inert steam which conveys it under pressure to said burner tangentially to spiral the same within a fuel tube around a coaxial central tube axially adjustable within the fuel tube to adjust the relation between flared distribution and mixing members respectively on the discharge ends of said tubes. Combustion air is fed coaxially around the discharge end of the fuel tube for thorough mixture with the coal which is conveyed with a minimum amount of steam through said tube so as not to deter combustion in the combustion zone which is immediately adjacent the discharge end of the fuel and central tubes.
