Abstract: Coal is an important energy as well as a significant industry raw material.However，the excessive application of coal will cause serious air pollution.Clean and renewable energy is an important alternative energy for urban coal.Among them，agricultural and forestry biomass energy with rich resources and rigid dispose requirements，has a very important role in the replacement of urban coal.Status quo and problems of biomass heating technology，which used for replacing urban coal，were summarized and analyzed.After that，two kinds of preferential developmental biomass heating technology were proposed，and two typical cases were introduced.The work was anticipated to provide suggestions for development of biomass heating technology.
