2018ISH heating HVAC industry event, fast Boiler "Thalia T7" was set aside to hold the event May 23, ISHChina & CIHE China (Beijing) International heating ventilation air conditioning, heat pumps fresh air and home comfort systems and technology exhibition in Beijing International Exhibition hot center opening.

Steam boiler and hot water boiler equipment What is the difference a, most importantly, the difference cargo: enough hot water boiler output facility triple the number of heat medium water; refers to 400ton diesel fired steam boiler purchased by turkey output was enough triple the number of water vapor. Second, a little difference on the auxiliary facilities: as hot water boiler facilities built with hot water circulating pump, steam boilers do not need; steam boiler water level gauge with the construction, facilities do not need hot water boiler; steam boilers with the construction of a separate package carbonated beverages, hot water boiler return water tanks and other facilities with points; Third, quality build process, install the furnace, the furnace application, the safety factor steam boiler specification states that some more stringent. Third, the most important difference is the application scenario, the steam boiler is to regulate the output Gao saturated vapor pressure, for electrical use, textile products, drugs and other aspects, therefore, the output is steam, thus force the vessel, heating installation of furnaces and furnace applications must be in line with relevant laws and regulations atmospheric pressure hot water boiler output of the heat medium is water, should not be a force utensils.

Prevention of industrial boilers produce condensate hazardous industrial boilers which produce condensed water hazard control measures which 1, bold and hydrophobic visible drainage pipe in the boiler inspection process and found that the condensate is not easy to accumulate in the water-tube boiler, while the horizontal boiler shell boiler drain more, but part of the boiler there is still a large amount of condensate (most of which are newly installed and running). The analysis revealed that, due to the large side of the boiler combustion space, even drainage arrangement, large diameter, tube bundle boiler convective condensation water formed can be discharged. Small smoke tube boiler combustion space levels, due to the structure until the drain can only be arranged at the bottom tube sheet boiler and after the drain of less than 30 mm in diameter, and designed to prevent leakage of boiler flue gas, directly connected to the drain pipe drainage pipes. In operation, the contents of the boiler easy to plug welding slag, rust particles. 2, to adjust the position of the economizer due to the large volume of the boiler, economizer boiler mostly installed in a horizontal tail position, while some horizontal boiler economizer housing is mounted directly or obliquely above the boiler flue outlet, the boiler the lowest point of the flue gas flow. Although the drain pipe installed at the bottom of the economizer, but due to gravity, most of the condenser, condenser and condenser will be returned to the boiler flue. During operation, condensed water after a long period of rinsing, immersed in a heating boiler section. Due to the different materials and material economizer boiler, economizer 09CrCuSb, designed using a material having a strong corrosion resistance, and without considering the design of boiler condensate corrosion conditions, 20g materials, poor corrosion resistance, easily corroded. 3, appropriately increasing the return water temperature in the boiler load or the energy efficiency of the testing process in industrial boilers, most of the boiler has a low load operation. Operated at the design load, the exhaust gas temperature before entering the boiler flue gas economizer is higher than the dew point, in the low load operation, the exhaust gas temperature of the boiler flue gas is lower than the dew point, so in the case of satisfying the condition, as far as possible should be boiler work in the vicinity of the design load, or take action. Measures could be taken to improve the return water temperature of the hot water boiler. For example, in the secondary heating system network, a network should decrease the flow, to increase the temperature of the primary water supply and return pipe network. Thereby raising the temperature of the flue gas leaving the boiler heating surface of the body, to avoid condensation of water vapor in the heating surface of the boiler body. 4, the depth of the condensed water recovered by previously described, the industrial gas boiler condensate is quite large, which is part of the condensed water is not effectively contain some depth using heat, in order to take effective measures to recover heat and water. For example, we may be adjusted by adding an alkaline agent (ammonia, cyclohexane, etc.) pH value of the condensate, which is then pumped into the heating system, which not only saves water, and heat is recovered.

Energy-saving renovation Technology of Coal-fired Boiler the operating parameters of blower and induced fan are directly related to the thermal efficiency and energy consumption of coal-fired boiler. The coal-fired boiler can be reformed with appropriate speed regulating technology, and the drum can be adjusted according to the load of the boiler during the transformation. It can not only save coal-fired boiler, but also save the power consumption of fan, so that the energy-saving effect can be achieved.
