Abstract
Данное изобретение относитс к области теплоэнергетики и позвол ет повысить точность степени загр знени поверхности нагрева парового котла за счет того, что врем изменени давлени в заданном интервале давлений измер ют после останова котла и при подаче в него охлаждающего воздуха с температурой в пределах от 10 до 50°С и расходом, обеспечивающим скорость потока воздуха в поверхност х нагрева в пределах от 1 до 3 м/с, а затем измеренное врем сравнивают с временем изменени давлени в тех же пределах, определенным при чистых поверхност х нагрева.This invention relates to the field of heat and power engineering and allows to increase the accuracy of the degree of contamination of the heating surface of a steam boiler due to the fact that the time of pressure change in a given pressure range is measured after the boiler stops and when cooling air is supplied to it with a temperature ranging from 10 to 50 & ° C and a flow rate providing air flow rate in heating surfaces ranging from 1 to 3 m / s, and then the measured time is compared with the time of pressure change within the same limits, determined with heating surfaces.
Description
Изобретение относитс к теплоэнергетике и может быть использовано дл контрол степени загр знени поверхностей нагрева парового котла.The invention relates to a power system and can be used to control the degree of contamination of the heating surfaces of a steam boiler.
Целью изобретени вл етс повышение точности измерени .The aim of the invention is to improve the measurement accuracy.
Способ осуществл етс следующим образом .The method is carried out as follows.
Котел с рабочим давлением пара PI и заданным значением уровн воды отключают и прекращают подачу воды в котел и отвод пара из котла. Затем измер ют врем изменени давлени в заданном интервале, подава при этом в котел охлаждающий воздух с температурой в пределах 10-50°С и расходом, обеспечивающим скорость потока воздуха в контролируемых поверхност х нагрева в пределах 1-3 м/с. Измеренное врем сравнивают с эталонным, определенным при чистых поверхност х нагрева, и поThe boiler with the operating steam pressure PI and the specified value of the water level is turned off and the supply of water to the boiler and removal of steam from the boiler is stopped. Then, the time of pressure change in a predetermined interval is measured, while supplying cooling air to the boiler with a temperature in the range of 10-50 ° C and a flow rate ensuring the air flow rate in the controlled heating surfaces within 1-3 m / s. The measured time is compared with the reference, determined with clean heating surfaces, and
