Steam boiler hot water boiler to common problems with rapid cooling rate and heat capacity of the temperature difference with a smaller two major advantages, which can increase the range of applications of heat transfer equipment unit, designed to increase the scope of process design heat transfer operation, and offers the possibility of some previous designs by heat, or thermal heat transfer rate limitations, such as small temperature difference heat recovery, cooling temperature difference is small, quick and precise temperature control and the like. So that it is possible, due to the plate heat exchanger are thin, although the heat exchanger. It should minimize the thermal deviation of each parallel tube heat set, for return into the boiler system should be taken to adjust the allocation. For general low temperature hot water boilers, hot water flow, the natural distribution may be employed, i.e. the amount of water entering each of the parallel pipes is set according to the size of the case and the heat resistance of each line of the natural distribution tube groups. NATURAL distribution structure is simple, but the difference in the safety and reliability of operation of the boiler, boiler for hot water, a relatively small amount of water, the natural distribution should not be used, but should be adjusted using the dispensing valve, according to the size of the heat pipe heat load group, the respective supply circulating water, to ensure that each parallel circuit outlet water temperature or less. In this case, the respective bias circuits outlet temperature within 10 degrees Celsius. Hot water boiler heating remodeled inner tube must maintain a certain flow rate to ensure that the heated cooling tube, to prevent oxygen corrosion and deposition of impurities in the water. For the downstream heat pipes should maintain sufficient water velocity. After the modification, should minimize stagnant water regions within the drum, particularly at the ends of the drum, or likely to cause oxygen corrosion, in order to precipitate and remove the water gas, the exhaust gas should be provided at the highest point of the respective loop boiler valve. When converted into a forced circulation hot water boilers, it shall be provided to prevent a sudden power outage, causing water vapor pot of measures to stop the pump.
Boiler excess air ratio is too low or too high, what harm? What causes high excess air ratio is? A: The boiler excess air ratio is one of the important characteristics of operational quality, the size value shows the degree of perfection combustion equipment and boiler operation. Excess air ratio is too low, incomplete combustion, increased flue gas of CO, the thermal efficiency is reduced; the excess air ratio is too high, the cold air does not participate in the combustion reaction in a large amount into the furnace, furnace temperature to drop, complete combustion. Also part of this excess of air also absorbs heat warming, and to take away the heat with the flue gas, reducing the thermal efficiency of the boiler. Therefore, a reasonable excess air ratio should not only ensure complete combustion of the fuel, but also can minimize the heat loss. Many cities now used in the boilers, a high excess air ratio, is because: (1) mechanical ventilation mismatches, to the excessive wind; (2) a furnace body, door, etc. leakage; (3) a flue, purification device air leakage.
Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water boiler is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).
Description of the need for the transformation of low nitrogen boiler manufacturers boiler is well known that the boiler is widely used in various fields of boiler heating production demand, and because of the unique advantages of the original, to a certain extent, a large number of integrated use, but as in recent years import advanced technology of the effectiveness of modern low nitrogen boiler sense of value has been further improved, so if improved by the upgrade of the original boiler, apparently to better meet the requirements of use and environmental fundamentally, and compared to the the need to re-purchase the content is clearly an advantage in the overall costs, and thus more and more low-nitrogen boiler owners will have to be achieved through the transformation of professional low nitrogen boiler Xi'an new low nitrogen boiler, the following article on the use of modified make a specific resolution. First, to better cost savings overall production efficiency in the use of boiler in use and the production process can produce, boiler work carried out necessarily need to be considered, compared to coal-fired or gas-fired boilers, low NOx combustion is dependent on the completion of combustion heating energy use is clearly lower costs further to meet the boiler needs to provide real value to assist rely on fundamentally sound technology to enhance the implementation and benefits of the integrated use of cost-effective. Good economic benefits can obviously be used in boilers to meet the fundamental requirements of the premise, which is itself more and more in recent years Why boiler manufacturers prefer low nitrogen through root cause of the boiler. Second, countries with mandatory community growing environmental requirements of the State Environmental Protection involve institutions have clear requirements for boilers burning pollution, while the new cast aluminum boiler low nitrogen emissions by introducing technology to reduce radically the entire effluent from the combustion, the boiler is low, during operation better conform to the national standards require the use of low-nitrogen emissions from the boiler. Gets National Accreditation production of low-carbon boiler can really provide protection for the realization of the production run, in order to realize the implementation of environmental protection and production integration. On the other hand relies on the transformation of low-nitrogen waste boiler and can not cause the original boiler, further give full play to its original value efficacy sense, but also in essence provides better preconditions for the execution and implementation of efficient production, so regardless of the overall transformation of low nitrogen boiler to start from the level of implementation which are necessity, not only to meet the state standards, it is able to import modern technology to achieve timely completion of the production technology implementation.
