Characteristics of boiler feed water. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. (deaerating heaters or membrane contractors)
When cutting a boiler in on a line equipped with two hand operated steam stop valves, the pressure on the boiler should be _____ line pressure. slightly lower …

High strengths are maintained in the low carbon grades by controlling the nitrogen content. T304 has higher carbon and a minimum solution annealing temperature to assure good long-time elevated temperature strengths. T304 grades are limited to 1650F under oxidizing conditions. Section I of the ASME Boiler Code lists allowable stresses up to 1500F.
Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the
