Based on the combustible islands, the feasibility of setting fire isolation belt in the large space building to prevent the fire spreading was discussed. With the knowledge of fire dynamic, the mode of fire isolation belt in large space building was built. To be convenient to engineering application, three typical courtyard fire was researched. The result shows that the fire power primarily affects the width of fire isolation belt. And 11.2 m wide fire isolation belt can effectively stop high-power fire spreading. When the fire power is determined, radiation from fire is much larger than the radiation from heat smoke layer. And when the height of single storey exceeds 15 m, the radiation from heat smoke could be neglected.
