Abstract

Abstract: In order to reduce the comprehensive costs of capital construction and improve the economic level of unit operation, a technical innovation is carried out in the air-gas system for one 330-MW CFB unit in a certain power plant. The scheme of single primary air (PA) fan and single secondary air(SA) fan is adopted for the first time in China, which significantly reduces the construction costs and land occupation. However, some new requirements are put forward for the air-gas system design accordingly. The half-a-year operation shows that single PA fan and single SA fan can operate stably and reliably with high efficiency and low maintenance costs.

Key words: CFB, air fan, single arrangement
