Background technology
Coal gas is a kind of high-quality, the efficient energy, has been the important goods on international energy market, and because its physics, chemical property are had nothing in common with each other, calorific value, density etc. all exists very big-difference; In the time that coal gas is measured, the calorific value of coal gas and flow are the important parameters that shows gas quality, wherein the calorific value accuracy that directly impact is measured especially.
In iron and steel enterprise, for coal gas, the especially feature of mixed gas diversification, adopts gas calorific value apparatus to carry out gas composition analysis more.Combustion-type caloric value instrument is that application heat balance principle is measured net heating value, when combustion gas and air mixed combustion, the stability of delivery temperature within the scope of 5 DEG C is measured, when temperature of combustion is during along with the mass change of combustion gas, correspondingly regulate the amount of cold air to be added to, the proportional relation of the amount of cold air and measured value, can calculate net heating value thus.(consulting Chinese papers net " application of gas calorific value apparatus is inquired into ")
Combustion-type caloric value instrument can carry out continuous, online automatic detection and control signal is provided the Wobbe index of coal gas, relative density, calorific value, constant composition, constant relative density for the Standard Gases of nominal heat value instrument in actual applications, and the fluctuation range of coal gas relative density is very wide in pipeline, that is to say, in pipeline, coal gas relative density can not be in full accord with Standard Gases.
In mixed gas, principal ingredient is divided from big to small according to ratio: N
2, CO, H
2, CO
2, CH
4, due to each composition proportion difference, cause coal gas in long-distance transportation through pipeline process, produce gas composition non-uniform phenomenon, the H of lighter weight
2be distributed to gradually the top of pipeline, the sampling of traditional gas calorific value apparatus only on pipeline perforate get gas, calorific value that obviously can not Measurement accuracy mixed gas after long-distance pipe transport.
