chemical boiler feedwater chemicals

Low nitrogen chemical boiler feedwater chemicals technology made a major breakthrough, however gratifying that through the unremitting efforts of domestic boiler companies, China's low-NOx combustion technology gradually into the world advanced list, catch up with a lot of foreign advanced technology.

Cause the chemical boiler feedwater chemicals 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.

Pet food factory steam chemical boiler feedwater chemicals

Pet food factories provide a variety of food for pets, and boilers are needed in the production process. More and more people are starting to raise pets and use it as a spiritual comfort, which is very good for pets. This has also led to the rapid development of various pet food companies. This has promoted the development of pet food factories steam boilers from the side.

First, regular inspections. Condensing chemical boiler feedwater chemicals is a large high consumption of industrial equipment, in order to avoid equipment failure affecting the situation in the course of work or dangerous, etc., the operator shall from time to time to carry out a full range of condensing boiler inspection and maintenance, main steam equipment valves, inlet and outlet valves and power and other parts to be checked. Second, the oil regularly. As the condensing boiler to run the state needs to ensure supply of water during prolonged high load, in order to avoid the situation hinder powering device appears in the case of prolonged friction and water erosion, the operator should pay attention to regular parts of the equipment plus lubricating oil, so that the various components of the apparatus to reduce the running resistance in working condition and to improve the operating speed of the device. Third, repaired regularly. In order to avoid serious loss situations condensing boilers present in long use, it should be regular equipment maintenance and inspection work, etc. during use, such as for some parts of the loss more serious for the conversion or for replacement of parts for use, but also to loosen the screws were tightened and the process of corrosion of parts for the conversion occurs.
