INTRODUCTION: At present, the most common way for rural heating is conjunction coal-fired boiler with Kang. Due to the economic restriction, the boiler's operation time is limited, which lead to low indoor temperature and poor indoor air quality. Base on this situation, the paper presents a new rural energy usage mode based on biomass briquette boiler, which integrated cooking, water heating bed, water-water heater exchanger into a system. The new model meets the functions of cooking, domestic

METHODS: In order to analyze the feasibility and performance of this new system, a contrast experiment has been made on two houses with basically the same size and structure in Chifeng, to test the bed's surface temperature of new mode, Kang's surface temperature under traditional heating system and their indoor temperatures. RESULTS: The test data show that the bed surface temperature of new mode is 4.2 higher than traditional Kang; Indoor temperature of the room with new mode is 5.1 higher than the room with traditional heating system; The cooling speed of new mode room is 1.4 /h slower than the traditional Kang heating system room during night. CONCLUSIONS: The experiment results indicate the thermal performance of new mode is better than traditional mode. What's more, the water-water heat exchanger in new system can satisfy the basic domestic hot water demands, which has a strong practical.
