摘　　要：锅炉汽改水应注意锅炉的供水和回水方式,考虑对流管束和水冷壁管的流量和流速,还应保证锅炉管板不受热变形,同时防止改造后的锅炉产汽、管束变形、管板爆裂等现象的发生,针对SHGN型锅炉改造方式的探讨尤为重要。When changing boilers steam into water,you should take care of the ways of water supply and water retum. Namely considering the floating amount and the floating speed to convection bank and water cooling pipe ; ensuring the boiler pipework not to be in the normal state uhen heated Mean - uhile, you should protect the following phenomena happenmg after the boiler reformeing after the boiler reformed：the boilers producing steam, pipe twisted and pipework broken, It is very important to research the ways of reforming the SHGNboiler.
