advantages of horizontal steam boiler
Periodic operation of boiler blowdown requirements a) to be performed when the boiler discharge pressure or low fire load, and should be stopped short; b) To the sewage before the boiler water level is raised to close the upper limit of normal level, the sewage water level to closely monitor, prevent boiler water; c) operates the drain valve, and if it can not be directly observed when the water level of the water level gauge. Water level monitoring personnel should contact the joint sewage; d) must discharge once every eight hours. If a common multiple boiler blowdown manifold, each boiler and the check valve when the outfall nor prohibited while sewage; E) for other operations not sewage, if necessary to perform other operations, stop sewage; f) when the sewage, first slowly open the valve opening closer to the boiler, and then intermittently opening and closing the valve opening away from the boiler quick, rapid discharge. After discharge, quick opening valve is closed first, and then slowly open valve closed, and then open the valve slightly open fast, close the water discharge after exhausted; End g) discharge operation, the discharge valve is closed, should be checked to confirm no sewage pipe outlet leakage.
Further, with respect to a conventional boiler, the combustion furnace is a more condensed closed, easily discharged flue gas and dust particles, are particularly prone to the phenomenon of gray block. Ash fouling early form of fluff, viscous connection block will occur after absorbing a large amount of acid, to further influence flue gas emissions, to promote the formation of acid, both affect each other, a vicious cycle. So, latent heat recovery boiler is not difficult, how rare is the solution to corrosion and plugging ash. 1, a secondary heat exchanger described formula: in such a conventional smoke vents installed fireplace plus a secondary heat exchanger device, also known as "false condensate." In fact, it is also a way of condensing the late 1980s and early 1990s was the development and use, Europe has been basically eliminated. While there are indeed condensation effect, but the premix and condensing technology currently on the market compared to vary greatly. At present, China and South Korea is part of the manufacturers. Advantages: low cost, rapid business transformation. Disadvantages: the acidic substance and the content of nitrogen oxides, corrosion resistance is poor. Mainly because it does not do a particular aspect of a combustion process in the main heat exchanger, too much excess air may promote the production of a large amount of an acidic solution, severe corrosion member. Therefore, such a condensing boiler even with increased corrosion of stainless steel, but the cost also determines the cost of his resistance to corrosion is very limited, short two condensing heat exchanger life. Which the non-air premix gas ratio, but also allows part of the heat loss. 2, cast aluminum finned coil description:
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
Whether specific differences between different types of alarms and gas-fired boilers need a gas boiler, which is a common and popular types of boilers, but also the product website, it is necessary to be familiar with and understand, because the only way to correct and reasonable use of this kinds of boilers, and make good use of the product effect, so that full use instead of wasted product. 1.6 tons of gas boiler, whether there are requirements on the consumption of natural gas? 6 tons of gas boiler, which is used to generate steam, if so, which generates between gas consumption and the tonnage of 1 ton advantages of horizontal steam boiler, from a professional point of view there is no relationship, is to look at the main boiler feedwater pressure and temperature, and, that there is a corresponding formula, depending on the furnace and different work efficiency, it is going to get a different result, therefore, to have a correct understanding at this point, can not go wrong. 2. purchase gas boilers, mainly to see what? It is necessary to install an alarm device? Buy gas boiler, which is an important task, and is an important aspect of this kind of boiler, it can not be ignored and careless treatment, because if contempt and careless treatment, then there will be the wrong choice, then, affect the product normal use, and resulting in product wastage and economic losses. Therefore, these conclusions will have, and the above requirements must be strictly enforced. In which the selection is to consider whether a discharge requirements, the type of gas used, the thermal efficiency of working fluid required, as well as hot water or steam to. The gas boiler, if the standard reference GB50041 "boiler design" is the need to install the alarm device, in particular, the concentration of combustible gas to install the alarm device, but also a boiler room of its specific requirements. And whether the type 3.SZS WNS-type gas boilers are different? From a professional point of view, the WNS and SZS type type gas boiler gas boiler Both models are compared, there is a significant difference, because SZS type gas boiler is a double boiler barrel vertical water-tube boilers, WNS type boiler for gas horizontal three-pass boiler tube fireworks. Further, SZS type gas boiler is mainly less than 10 tons of gas boiler, gas-fired boiler is mainly WNS type of gas boiler 10 tons, are in tonnage, structure and properties are significantly different.
