The invention relates to a method for reducing the hysteresis error of out-precipitated martensitic stainless steel elastomer. The method comprises the following: a step of performing solid solution, which is to heat a bar with a furnace at a speed between 5 and 30 DEG C per minute, heat the bar to 1,040+ / -10 DEG C, preserve heat for 1 to 4 hours and compulsively cool the bar to room temperature;a step of deep cooling, which is to cool the compulsively cooled bar in liquid nitrogen at a cooling temperature between 70 and 90 DEG C below zero for 2.5 to 6 hours; a step of performing deformation processing, which is to stretch or compress the deep cooled bar at a speed less than or equal to 5 millimeters per second at normal temperature and control the elongation or compression ratio of thebar in the stretching / compressing direction between 1.0 and 5.0 percent; a step of aging, which is to put the deformed bar into a heating furnace at a temperature not higher than 200 DEG C, heat the bar with the furnace at a speed between 5 and 30 DEG C per minute, raise the temperature to 480+ / -5 DEG C and preserve the heat for 2.5 to 5 hours. The method improves the capability of out-precipitated martensitic stainless steel in resisting micro-region plastic deformation, and reduces the hysteresis error of weighting sensors.

The invention provides a boiler system. The boiler system performs automatic control according to the amount of steam generated by a boiler and the amount of water fed into the boiler; sewage is discharged from the boiler at regular intervals; a steam pocket comprises a water quality analyzer which is used for measuring the quality of water in the steam pocket; the steam pocket is connected to anascending pipe and a descending pipe; a plurality of cutting heat exchange parts are arranged in the ascending pipe at intervals and extend in the height direction of the ascending pipe; and a plurality of holes are formed in the cutting heat exchange parts and run through the cutting heat exchange parts in the height direction of the ascending pipe. The boiler has the effects of flow rate stabilization, vibration absorption and noise reduction and avoids the wasting of lots of energy sources caused by the failure of the boiler sewage discharge system.

The invention provides a boiler system. The boiler system comprises a monitoring diagnosing controller and a boiler; the boiler comprises a pollution discharge pipe arranged at the lower end of a boiler drum, and a pollution discharge valve is arranged on the pollution discharge pipe; a central diagnosing monitor automatically sets the pollution discharge time according to the measured PH value, so that the pollution discharge amount is automatically controlled; and the pollution discharge speed is increased continuously along with the increase of the pH value, and in addition, along with theincrease of the pH value, the continuously increasing magnitude of the pollution discharge speed is smaller and smaller. According to the boiler system, the change of the relation between the pollution discharge amount increasing magnitude and the pH value can correspond to the actual pollution discharge amount, so that the pollution discharge efficiency can be improved as soon as possible, and the heat loss is avoided.
