The heating type in northern China is becoming more and more concentrated, and the demand for heat supply is increasing. The thermal power market is increasingly strict with the heating flexibility of the unit. The adoption of new heating technology is an important means to solve market demand. The cylinder transfer technology has attracted wide attention because of its significant benefits, low investment cost and broad application prospects. This paper introduces and analyzes cylinder transfer technology, and compares it with the heating capacity, peaking-shaving capacity, economy and safety of the traditional steam extraction technology. The comparison results show that the cylinder transfer technology has obvious advantages, and it has the heating property with strong heating capacity and good heating characteristics.
