Description

Изобретение относитс  к области контрол  процессов в паропроизвод щих установках и может быть использовано дл  определени  объема пара под зеркалом испарени  в барабанном котле. Известен способ определени  объема пара под уровнем воды путем отбора проб воды при наличии и отсутст .вии пара, причем об объеме пара су} , т JIO положению уровн  воды в пробоотборнике 1. Этот способ  вл етс  наиболее близким к изобретению. Недостаток его состоит в низкой точности при определении объема пара под уровнем воды в барабанном котле, где паросодержание существенно мен етс  вдоль испарительного тракта, а последний как правило, имеет сложную конфигура цию. Цель изобретени  - повышение точности определени  объема пара под зеркалом испарени  барабанного котла Указанна  цель достигаетс  тем, что уровень воды поддерживают посто нным , а в последнюю предварительно ввод т негидролизуемую и нерастворимую в паре соль-индикатор и измер ют ее концентрации-в пробах, а об ме пара над уровнем воды суд т ормуле S.VjTSoVnp м -v - n-V Sj и концентрации соли-индикатора при наличии и. отсутствии пара соответственно , объем пара под уровнем воды в барабане, объем водного контура котла по рабочий уровень воды в барабане, (р - объем отбираемой пробы, удельный объем пробы при нормальных услови х , удельный объем воды на линии насыцени . пособ осуществл ют следующим об-, м. отел заполн ют водой по рабочий ень, соответствующий стационарнагрузке , при которой необходировести измерение. В котловую ввод т негидролизye yю и нерастм1то в паре соль-индикатор, наер хлористый натрий, отбираютThe invention relates to the field of controlling processes in steam generating plants and can be used to determine the volume of steam under an evaporation mirror in a drum boiler. There is a known method for determining the volume of steam under the water level by sampling water in the presence and absence of steam, moreover, about the volume of steam}, t JIO to the position of the water level in the sampler 1. This method is closest to the invention. Its disadvantage is low accuracy in determining the volume of steam below the water level in the drum boiler, where the steam content varies significantly along the evaporation tract, and the latter usually has a complex configuration. The purpose of the invention is to improve the accuracy of determining the volume of steam under the evaporation mirror of a drum boiler. This goal is achieved by maintaining a constant water level, and lastly introducing a non-hydrolyzable salt-indicator insoluble in steam and measuring its concentration in samples At the vapor level above the water level, the formula S.VjTSoVnp m -v - nV Sj is judged and the salt indicator concentration in the presence of and. the absence of steam, respectively, the volume of steam under the water level in the drum, the volume of the water circuit of the boiler at the working water level in the drum (p is the volume of the sample being taken, the specific volume of the sample under normal conditions -, m. The calving is filled with water at a working day, corresponding to the stationary load, at which the measurement must be carried out. Negrolysis is introduced into the boiler room and unspent in salt-indicator steam, sodium chloride, taken

пробу воды и определ ют концентрацию в ней соли-индикатора. Далее ввод т котел в действие и устанавливают заданную стационарную нагрузку, под-держива  уровень воды в котле посто нным . Например, регулированием подачи питательной воды. Повторно отбирают пробу котловой воды, охлаждают ее до комнатной температуры и определ ют концентрацию в ней солииндикатора .water sample and determine the concentration of salt indicator in it. Next, the boiler is put into operation and a predetermined stationary load is established, keeping the water level in the boiler constant. For example, by regulating the feed water supply. Sample the boiler water again, cool it to room temperature and determine the concentration of the salt indicator in it.

Расчет объема пара под уровнем воды производ т по приведенной выше .The calculation of the volume of steam under the water level is made according to the above.

Применение предложенного способа позвол ет повысить точность определени  объема пара под уровнем воды . барабанного котла.The application of the proposed method allows to increase the accuracy of determining the volume of steam under the water level. drum boiler.
