[Abstract]Hebei Huadian Shijiazhuang Luhua Thermal Power Co.， Ltd. adopts a positive pressure dense phase double casing pneumatic ash conveying technology. With the increase of operating time， problems such as increased gas consumption， insufficient ash conveying output， and severe wear and tear of pipelines and equipment occur. The article renovates the original ash conveying system by applying pilot low-pressure conveying technology and conducts performance tests on it， comparing it with the original ash conveying system in terms of gas consumption， conveying pressure， conveying speed， output， and conveying frequency.
