【正文】 及價格等因素，本工程采暖用氣 一期工程按 10%考慮，即年用氣量為 60萬立方米；二期工程按鍋爐用氣量的 35%考慮，即年用氣量為 210萬立方米。 公建及商業(yè)用戶用氣量指標 影響商業(yè)用戶用氣量的因素包括地區(qū)的氣候條件，居民使用公共服務(wù)設(shè)施 的普及程度，用氣設(shè)備的性能、效率、運行管理水平和使用均衡程度等。在提高城市社會效益的同時，項目建設(shè)單位也將在天然氣工程的 建設(shè)和持續(xù)發(fā)展中獲 得相應(yīng)的回報。位于郟縣、汝州、禹州三市縣交界處的三管山為全 縣最高山峰，海拔 。 因此，從某種角度講， 21世紀天然氣將大有作為。 河南省郟縣天然氣利用工程 可行性研究報告
