The comparison of boiler failure rate: 1, vacuum degree of vacuum boiler in vacuum boiler * important index of stable operation of furnace, and four main factors that often affect vacuum degree: 1) whether there is leakage point in boiler body and valve, instrument, and so on. At present, including imported valves and meters can not ensure that there is no leakage within 3 years. 2) it is inevitable that failure of control part, boiler controller and negative pressure, pressure controller will also happen in operation, for example, the failure rate of domestic controller is even higher. 3) vacuum pump, three-way solenoid valve is working normally or not. As a result of the vacuum pump, the three-way solenoid valve is not operating very often and is originally installed Mouth also easy to appear the card dead and in the operation occurs the fault. 4) the load can not change abruptly, the boiler load change is very normal for the boiler, generally, the boiler can meet the load regulation of 30% ~ 100%. The above faults will cause the change of the vacuum degree of the boiler. At this time, the gas tightness of the boiler, whether the control part is normal or not, the vacuum pump, the three-way solenoid valve are normal or not, and the change of load should be checked. If all normal should be checked negative pressure and pressure controller settings, all normal vacuum recovery boiler can still be normal, otherwise the boiler should be shut down and overhauled all-round inspection. The failure maintenance rate of vacuum boiler in actual operation is higher than that of existing boiler. Pressure steam boiler, control requirements are higher than steam boiler. 2. The normal pressure boiler only has the basic time, temperature, water level control, hot water boiler controller selected the original inlet, the failure rate is relatively low. There is no need to maintain vacuum control equipment, without complex control equipment, personnel operation requirements are simpler than vacuum boilers, the probability of downtime maintenance is less, the actual operation of hot water boiler is much more stable. The comparison of boiler safety: 1. If the vacuum degree of the vacuum boiler is not guaranteed due to the above four factors, it may cause the boiler pressure to rise rapidly, and the boiler body is a closed structure, and the operator may cause the boiler pressure to rise rapidly. If paralyzed, it is possible to become the danger of pressured steam boiler, the vacuum operation of vacuum boiler is more safe based on the premise that the vacuum degree of boiler can not appear problem. 2. The atmospheric hot water boiler of atmospheric pressure boiler is as simple as boiling water, and no fault will cause boiler pressure. The boiler www.boilermanufactory.com is more safe and reliable, and it is really free of any danger.

What boiler for Textile mills?

List ofboiler machine for Textile Mills and Apparel Industryisclosed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy. These are fired units for heating or vaporizing liquids other than water where these units are separate from processing systems and are complete within themselves.

Vacuum Products vacuum boiler boiler is a hot water boiler, water heater, also called vacuum, vacuum boiler from the basic principles of the 1972 Zurich University of the invention. Vacuum boiler is mainly used for civilian heating, can be used in specific situations hotels, residential areas, commercial establishments like heating, sanitary hot water heating. Vacuum boiler vacuum boiler works a negative pressure vacuum is formed in a closed environment inside the furnace, the heat medium is filled in the body of water. Or otherwise heated by combustion heat medium water, heat medium water is heated to generate steam, the water heat exchanger heated by the pipe of the condensing heat exchanger, to achieve the supply of hot water. Vacuum boiler leak leak detection method described may be employed soapy water pressure. Wipe the first leak site (e.g., wire head, flange, etc.), and find a diameter 3-4mm thick sheet or plank is placed between the disk and the blade is about 80mm, prevent the boiler pressure proof sheet is bulged blade punctured. Allow operation of the burner, turn off the vacuum and high vacuum diaphragm valve means, so that the pot 0.05MPa pressure rise, closing the burner, pressure, liquid soap applied with a brush in the presence of all possible leak site, carefully, if leakage point will produce bubbles. Note that the pot pressure should not exceed 0.1MPa! For an examination site: explosion-proof valve, high vacuum diaphragm valve (hose connection), the furnace outfall seat, mirror, automatic vacuum device, a pressure control means on the furnace level, water temperature and other probe mounting interface. Found leakage diaphragm valve position required to open the high vacuum vapor discharge, reinstall the leak. After installation is complete again with soap and water leak detection method for detecting pressure, missing dots after confirmation, closing the diaphragm valve is opened after the high vacuum vapor release, and the plates come between the blade and the disk, closing the circulation pump, and then evacuated so half an hour to run the apparatus evacuated to a vacuum state.
