针对某电厂高压加热器上端差过大的问题，通过分析找出了上端差过大的原因是高压加热器水室隔板处有漏泄，给水形成“短路”，提出对高压加热器隔板进行更换、补焊堵漏、更换垫片、上张紧螺栓等处理方法。改造结果表明：每年可节约供电成本75.8万元，节能效果明显。
針對某電廠高壓加熱器上耑差過大的問題，通過分析找齣瞭上耑差過大的原因是高壓加熱器水室隔闆處有漏洩，給水形成“短路”，提齣對高壓加熱器隔闆進行更換、補銲堵漏、更換墊片、上張緊螺栓等處理方法。改造結果錶明：每年可節約供電成本75.8萬元，節能效果明顯。
침대모전엄고압가열기상단차과대적문제，통과분석조출료상단차과대적원인시고압가열기수실격판처유루설，급수형성“단로”，제출대고압가열기격판진행경환、보한도루、경환점편、상장긴라전등처리방법。개조결과표명：매년가절약공전성본75.8만원，절능효과명현。
FAiming at the problem of upper end differential larger than normal in high pressure heat-er of a power plant, by analyzing finds out the fault cause is the water chamber clapboard of high pres-sure heater occurring leakage, feed water cutting out, and puts forward the treatment method such as to replace or weld the clapboard, change the pad and fasten the bolt. The improvement result shows that the effect of energy saving is obvious, which can save 758 000 yuan yearly.
