Abstract: Natural trend of improving and upgrading civil heating, and the necessity and urgency of optimizing source and heating mode in north China county town were expounded in this paper. According to the current situation of garbage disposal and civil heating within north China county area, the matching relationship between the amount of garbage generation and civil heating demand was studied. The optimal heating mode (central heating mode within a typical county town based on combined heat and power generation by garbage incineration) was obtained and presented in this paper in order to provide a kind of clean, environmental, economic, efficient, recyclable, safe and reliable civil heating mode in line with the concept of sustainable development (energy resource, heating source and heating system) for upgrading people’s life quality in most north China county towns sustainably.
