Study Of Key Problems Of Natural Gas Planing Development Of Jinan

To solve the problem of Jinan city gas development exist the following problems: JinYuanQi reasonable predictions of demand for natural gas development; Natural gas pipeline system construction standard is low, the shortage problem of ability; The selection of gas heating means;(1)Through multiple gas demand forecasting method to determine the actual demand of jinan, collection of jinan city in recent years, gas gas and gas load variation rule of the data, analysis of gas regularity of all types of users, and staging user for load forecasting, Considering gas inhomogeneity, in different periods of gas balance calculation, draw on calculate to calculate all kinds of gas users24hours.(2) Analysis to determine the Jinan high pressure pipe network layout, the establishment of hydraulic calculation chart, using the method of solution of node, under different working conditions of high pressure ring gas supply capacity hydraulic calculation analysis;(3) Source more high pressure annular pipe network segmentation is proposed to calculate the cumulative superposition calculation method, analysis and calculation of high pressure ring network under different conditions of gas storage capacity;(4) By way of gas heating and the analysis and research of gas stations layout, gas heating mode that is suitable for the development of jinan and gas station layout;(5) Finally, the planning of energy conservation and emissions reduction effect has carried on the analysis and calculation.This article research results for the Jinan urban fuel gas development planning (2013～2020), both within the planning in2013by the experts, and by the Jinan government notation.
