Alginic pyrolysis oil, semi-coke combustion system and a two-cycle treatment composition

The present invention relates to the use of raw material resources, especially a seaweed pyrolysis oil, two-cycle system and a combination of char combustion treatment. The present invention is a pyrolysis furnace as a fast bed, circulating fluidized bed is to use char combustion means to the heat carrier circulating fluidized bed combustion ash generated by thermal cycling and noncondensable gas as a pyrolysis furnace. Alginate fragments were separated in an exploded heated gaseous pyrolysis bio-oil formed in the furnace and non-condensable gas, char quickly discharged directly into the bed outlet CFB, produce high temperature flue gas enters the gas-solid separator, down feeding the fly ash into the shuttle valve further pyrolysis bed as the heat carrier, flowing through the flue gas dust tail heating surface, and finally into the atmosphere, heating the steam generated by the tail heating surface for heating and power generation. Thus truly integrated and efficient use of algae biomass.
