gas hot water vacuum fire tube boiler price

Those projections vacuum boiler good properties: the name comes from the vacuum boiler boiler interior air is a little low pressure environment, by automatically evacuating device, so that a negative pressure is formed inside the body closed vacuum environment, in accordance with the boiling point of water at a low temperature reduce the principle, faster generation of steam, there is no danger of explosion expanded, widely used in the higher elevations. Then, vacuum boiler specifically what has good performance? 1, the internal structure of the boiler will not corrode a negative pressure vacuum in a vacuum state, is completely isolated from the outside atmospheric pressure, so the configuration of each unit boiler exhaust pump will continue to discharge the steam inside the unit, internal organizational structure will not cause corrosion, so the vacuum phase transition boiler in terms of durability, performance is quite good. 2, and the different secure and normal atmospheric pressure boilers, air is evacuated vacuum boiler child vacuum environment inside the container are formed, so that during use, the furnace operated at vacuum-like body, and not due to heat produce swelling, but do not belong to the pressure container, and therefore there is no risk of explosion. At the same time, due to a fault or if other factors believed caused by increased pressure, the vacuum pressure switch will automatically cut off the power supply, so in terms of security vacuum boiler is more reliable than other types of boilers. 3, long life oxygen precipitation in the vacuum boiler water running alongside the intermediate medium outside of the furnace, so long as the small amount of heat added in one aqueous medium, the calcium and magnesium ions can be limited, so that fouling does not occur inside the boiler, thereby increasing boiler use of life.

We learned that recently, the city of Wuwei in Tianzhu county government announced that it will carry out a comprehensive coal-fired boiler demolition "clear" action aimed at remediation efforts to increase coal-fired boilers, and resolutely fight pollution control tough fight, complete coal-fired boilers out of the grid, clean energy transformation of the task of governance and compliance. The task of governance staff, shimenzhen government, Hua Temple town government organization done by the Bureau of Wuwei City, the ecological environment will Tianzhu Branch, and Hua Temple shimenzhen government and town homes for the elderly failed fork Station coal-fired boilers were concentrated tear down. To continue to improve the air quality of the environment, protect the health of the people made great contributions.

Tianzhu County will further promote the comprehensive improvement of coal-fired boilers, and through the elimination of the demolition, clean energy transformation, environmental compliance management, etc., with the completion of the internal area of ​​coal-fired boiler remediation tasks, achieve discharge standards in all coal-fired boilers. Meanwhile, the industrial park central heating, phasing out central heating, and for 10 tons of steam coal-fired boilers in the gas pipeline network coverage.

Up to now, Tianzhu County by incorporating central heating, clean energy transformation, compliance management, has completed the renovation of 74 coal-fired boilers. The remaining four coal-fired boilers in Tianzhu Force has developed a program of clean energy for heating reconstruction project, planned in June renovation, completed in August.

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.

How discharge of sewage vacuum boiler (1) inside the drain valve is opened; (2) Slowly open the outer discharge valve, for discharging sewage and heating pipes; (3) off and on repeatedly outer drain valve, a buffer scale pot so trying to scale discharge ; (4) bonded on the inner blowdown valve, the water in the discharge between the two discharge valves; (5) engaged on the outside of the drain valve, complete discharge of sewage.
