供暖单位为降低供暖运行开支，都希望供暖热水锅炉在超负荷下运行。但是，供暖锅炉超负荷运行时，锅炉的效率如何，是否从根本上降低了运行成本。对这一问题，我们在１９９７～１９９８供暖期做了大量的测试工作。根据实测结果以及近几年的运行经验，我们从如何实现超负荷... Heating Units In order to reduce heating operation expenses, it is hoped that the heating hot water boilers will operate under overload. However, when the heating boiler is overloaded, how effective the boiler is and whether it fundamentally reduces operating costs. For this problem, we did a lot of testing work during the heating period from 1997 to 1998. Based on the measured results and operating experience in recent years, we have achieved how to achieve overload...
