Proper Circulation Critical to Effective Boiler Cleaning

摘要

In the 1960s and early 1970s, the cyclone boiler was a popular choice for new coal-fired power plants. Cyclone combustion produces a high heat output while maximizing combustion efficiency. The primary drawback to cyclone fuel burning is high NO_x production, which has led some utilities to switch to other combustion techniques. Nonetheless, many cyclone units are still in operation throughout the country. The unique configuration of the cyclone barrel, however, can make internal tube cleaning difficult. This article addresses a straightforward method to improve chemical cleaning of cyclone boilers.
