Cause the boiler normal outage due to natural blood pressure steam having a saturation temperature at a certain constant pressure, when the pressure change, the saturated water and saturated steam temperature change accordingly. If the boiler shutdown pressure drops too fast, the saturated water and saturated steam temperature dropped significantly. Due to the high rate of change of pressure saturation temperature at a lower pressure, because the saturated vapor in contact with the drum wall, the lower wall in contact with saturated water vapor than the thermal conductivity of water is large, the heat accumulator drum lower wall water to pass quickly the drum wall at a temperature close to the saturation temperature at the new pressure after the pressure drop, and poor heat transfer walls of the drum to maintain a higher temperature, the drum wall temperature is higher than the wall temperature, the faster the vapor pressure drop, the drum, the greater the temperature difference between the lower wall. Simultaneously vapor pressure decreased too fast, which also decreases the saturation temperature corresponding to accelerate the wall temperature waterwall, economizer header and the faster decline, due to the rapid cooling, the contraction will have a great thermal stress, local joint, at the weld easy to crack, so the boiler outage to take normal blood pressure naturally. When the normal flame boiler shutdown, soft drinks all doors should be closed, closing dampers, Manhole the boiler is in the closed state, allowed to cool down.
Dry condensing boiler maintenance condensation boilers belongs to a boiler, condensing boilers require regular maintenance, we watched the small series in detail. After maintenance shutdown dry 1, the boiler water exhausted, scale remove soot, slag and furnace heating surface. Boiler water supply pipe 2 is closed, water supply, the valve on the outfall, or blocked by the separator Yan, completely isolated from the other operation of the boiler. 3 open manhole, hand hole, the boiler naturally dried if wet boiler, and with a slow fire the boiler furnace wall flue drying. 4 selected amount desiccant. Common desiccant anhydrous calcium chloride (of CaCl2) and quicklime (CaO2), CaCl2 2kg per cubic meter of volume of water placed quantitative, requires selection of particles of about 15mm; lime 3kg per cubic meter of the volume of water placed quantitative, requires selection of 10mm ~ 30mm lumps. After drying the boiler 5, the tray containing a desiccant and the release drum furnace in order to absorb moisture, not in direct contact with the desiccant required boiler heating surface. 6 desiccant should be placed once, to see whether the heating surface corrosion in the boiler regularly checked every week a month, the timely replacement of the desiccant failure, a month later inspected once every two weeks.
It is understood, Shaanxi Province, 2018 - Continuing to promote the 2019 inspection work in key areas of defense sky war, now in its third phase. November 22, according to the requirements of the program of work for the inspection team to carry out all the Guanzhong area of Shaanxi Province counties (cities, districts) inspection work, inspected 262 units, identify problems and 49, have been transferred to the supervision of Shaanxi Province 20 .
