On February 11, the country’s first 500-ton class tower boiler owned by **Energy Group’s Suqian company in Jiangsu successfully completed its blowing process and passed the performance testing, marking the entry of the project into the phase of full-scale commissioning trials. This project is part of Jiangsu Province’s 14th Five-Year Plan for cogeneration initiatives. It introduces in China key technologies such as a 500 tons per hour capacity tower furnace, exhaust gas reheating using backpressure machines, and a single-row high- and low-temperature dual-pole high-efficiency rotary air preheater. Once completed, it will ensure a reliable supply of heat to meet the thermal needs of regional economic development. The boiler steam purging operation carried out this time is a crucial step prior to the commissioning of a newly built power unit. Its purpose is to use steam to remove various impurities that remain in the boiler superheater, reheater, and steam pipes during manufacturing, transportation, and installation, thereby ensuring the long-term safe and stable operation of the unit. During the blowpipe operation, the company coordinates various parties including designers, commissioning teams, constructors, supervisors, and equipment suppliers, to ensure strict control over safety, quality, environmental protection, and project schedule. To address potential noise pollution, the company strictly fulfills its environmental protection responsibilities by completing the necessary procedures for reporting noise pollution in advance. It also formulates comprehensive noise reduction plans and emergency response measures. By properly designing temporary systems and installing noise reduction devices, it ensures optimal performance of the systems while effectively controlling system resistance and environmental noise, thus establishing a robust dual defense mechanism for both safety and environmental protection.
