hydraulic test fixtures steam boiler agents

Boiler continues to operate, the temperature sensor and temperature data are collected continuously transmitted to the controller, as the heating temperature gradually rises to the combustor 53 degrees. At this time, by setting the temperature controller and the current temperature of comparison, determining the water close to the set oven temperature, thus lowering the flame and pilot burner. As the temperature is set closer to 55 ℃, the burner can be based on the actual frequency of the heat demand, precise control of the size of the flame, by gradually close, maintaining the temperature at 55 ℃. When the heat demand changes, the flame will make a corresponding change in the boiler only works to maintain the temperature of the state, to avoid unnecessary waste of resources.

Steam and Hot Water Boilers What is the difference: Steam and Hot Water Boilers What is the difference between the difference in use of the boiler, hydraulic test fixtures steam boiler agents and hot water boiler are many:? The main boiler steam boiler, steam as a heat transfer medium The main advantages are: a small thermal inertia, heat faster when the steam supply, while the cold steam stop something else. 2. Low cost, wide adaptability, to meet the various requirements of users with different heat requirements for simultaneous pressure and temperature;. 3, non-toxic, food can be heated directly, even if there is no leaking cause environmental hazards; 4 high steam temperature, a large latent heat of vaporization, the heat transfer area can be reduced relative to the hot water device, reduce costs;. Since the heating medium steam condensate recovery is difficult, resulting in waste and water latent heat. Even with condensate recovery, condensate recovery in the process, because water easily dissolved oxygen and other impurities, but also easy to cause harm to the boiler. Oxygen to water, salt and other impurities cause boiler fouling and corrosion problems affecting the safety and energy efficiency of the boiler water as a heat medium for air conditioning, heaters, low temperature oven drying apparatus, hot water tank and each textile species of low-temperature heating, air conditioning equipment and heat transfer coil. Hot water as a heat medium has the following advantages: 1. Generally the lower the heat medium water temperature of the heat medium, and large temperature difference between the flue gas, boiler exhaust gas temperature is relatively low, and thus higher boiler efficiency. 2. Closed hot water supply system small amount of water and sewage rate is much smaller than the steam boiler, waste water is also smaller. And lower boiler water quality requirements, less the cost of water treatment. 3. The specific heat capacity of water is large, a large hot water system capacity, strong heat storage capacity. When the thermal conditions or hydraulic failure condition a short time, without significantly heating conditions cause large fluctuations. 4. pump hot water heating system can be used for long-distance transportation, a small heat loss, heating large radius, to adapt to the requirements of urban planning central heating. Steam and Hot Water Boilers What is the difference? The most fundamental difference is that a hot water for a steam, hot water boiler is the production of hot water for heating boiler. Hot water boiler and steam boiler are water as the working fluid, which produce steam, hot water production former.

Hot water boiler maintenance during maintenance shutdown hot water boiler shutdown period: Xiao Bian below to introduce the hot water boiler maintenance fast boiler is well known in Henan, China's most northern end of the heating season is six months, from October 15 to 4 May 15. In industrial production, hot water boiler to the heating in winter can be used. After the winter heating season, the hot water boiler will be idle. To ensure the normal operation of the hot water boiler next year, can not relax to maintain idle period. 1. When idle, the boiler water is discharged and should be placed in a ventilated place. 2. Cracking furnace boiler for hot water maintenance problems, professionals should be repaired, if necessary Lubricate or anti-corrosion coating on the surface of the furnace. three. Different methods and disintegration downtime 1, boiler water drained, draining suction process when the boiler is shut down three days or less, ammonia and hydrazine before shutdown, feedwater PH value to 10 or more, and then a certain pressure the drainage furnace, keep the system dry. 2, the film formation method when the amine protecting the boiler stopped more than 4 days, the protective effect of the film formation is preferably an amine, such as stearyl amine protection, i.e. before the shutdown should be added to a suitable liquid to vapor octadecylamine protection system for protection. 4. Different methods used during the non-disintegration of the stop 1 and, maintaining the gas hot water boiler pressure method: discontinued within 1Od, discontinued before increasing ammonia, hydrazine dosage of the feed water to raise the pH above 10, to maintain the boiler pressure. 2, gas protection law: outage if more than 10 days, in the gas phase protection, protection of the boiler for a long time. Fifth, the gas hot water boiler shut down for maintenance Desiccant method, the boiler water temperature dropped to 100-120 (?) All C is discharged, the water in the furnace, the dry heat boiler metal surfaces, all of the scale, the slag within the system clean, and a desiccant to keep dry the metal surface, to prevent corrosion.
