condensing gas mercial hot water boiler

Chinese wine culture has a long history, wine blend. In the process of making wine, almost all wine prices are inseparable from the brewing process steam, we can say the stability and quality of steam purity of the wine production plays a decisive role. Lefort Wine has been committed to producing high-quality wine products, December 2016 No. 1, Lefort wine and I signed a one 4 tons of steam condensing steam boilers, the company continues to provide high-quality wine work steam.

Methods of operation and precautions gas steam boiler steam boiler with a gas advantage of social development is increasingly clear that the future economic level to enhance people will focus on comfort. Throughout the heating market innovation Although several decades of history in the worldwide gas boiler, but because of China's housing form, heating the environment and foreign difference is relatively large, there is currently in use gas boiler, there are still some unresolved issues The problem. Gas-fired boiler during use, the pipeline can be said is essential. Gas-fired steam boiler pipeline system is necessary to ensure normal supply of natural gas equipment, must pay attention to anti-corrosion of boiler tubes gas. Pipeline gas boiler heating system after a long period of use, will gradually varying levels of wear and degradation slowly, then the gas boiler pipeline corrosion problems which need to pay attention to it? Gas steam boiler heating pipe residual soldering flux has not been removed leaving a clean and cause corrosion in the water system, these regions are more easily aggravated rust corrosion, a long time would cause a pinhole on the heat sink, resulting in leakage. Some flux comprising an organic acid, bis more metals together form electrolytic corrosion effect. The most common heating systems made of stainless steel and iron materials with copper, galvanic corrosion occurs between the iron and copper, in which case, the corrosion rate of steel will be faster than the copper. Since the gas boiler system design, such as a bad selection pump, or the position of the obturator when the bad systems are not very good, the external negative pressure will pump air into the system, so that oxygen in the air system to accelerate corrosion of metal. Will have a good ability to maintain self-neutral water quality, but when the water quality is not good, there are a lot of home electric boiler condensing heat exchanger made of aluminum materials, aluminum is due to the appearance of easily forming a dense aluminum oxide protective film this layer of oxide film can easily be removed by acidic or basic water, resulting in occurrence of corrosion. The metal heating apparatus of the system generated during cutting, the whole or partial etching adhesive residue bonded pipe, as well as some mineral oils, residual casting sand and radiator systems of microorganisms in the system will be increased.

The water tube boiler and the fire tube boiler are two kinds of boilers with great differences. Although both are oil and gas boilers, ZBG WNS series fire tube boilers and SZS series oil and gas water tube boilers have their own advantages.

Preparation and method for measuring the moisture content of the flue gas of the boiler before the boiler purchase this product knowledge and understanding, the present, it is necessary for two reasons, first, it is the site of important product and the main key one word, and second, the products are widely used, why we have these conclusions and specific requirements. Meanwhile, I hope that we can be taken seriously and, in order to have learned well and apply their knowledge to practical work flexibly. Is there some preparatory work before the boiler 1. buy? Boiler products to buy, this is an important job, and need to be taken seriously, but also want to take into account all relevant factors, in order to have accurate judgments and the correct choice, a good choice to avoid mistakes. Before carrying out this work, is the need to do some preparation, use of the product to the environment and have a clear understanding of the requirements and learn about product origin, specifications, technical parameters, materials, quality, price, service and product manufacturers these and other basic information, in order to compare and consider, then, the right to choose their own products. 2. whether Sheung Shui before the boiler starts have specific requirements? From a professional point of view, Sheung Shui before the boiler starts, there are some basic requirements, which specifically is: If the condensing mercial hot water boiler, the water speed before it starts not too fast, not be less than the winter time Sheung Shui 4 hours, in other seasons upper water time of not less than 2-3 hours. And, at the beginning of the water, its water speed to slow. If the boiler is cold, it's inlet temperature in the range of 50 ℃ -90 ℃, and the difference between the water temperature and the temperature of the drum wall into the steam drum, not greater than 40 ℃. 3. What is the chain boiler? Chain boiler, which is a particular kind of a boiler, a higher degree of mechanization layers fired boilers, the time the track grate with a chain similar to these so called chain boiler A boiler. Further, it is a pre-boiler, the coal combustion process is completed in the movement. Advantage of this kind of boiler, the combustion condition is stable, high thermal efficiency and easy operation, in addition, its low concentration of dust emissions. However, it should be noted that the moisture content of the larger, more ash and strong coking coal, not suitable for this kind of boiler for combustion. 4. How the moisture content in the flue gas boiler measured? Determination of moisture content in the boiler flue gas, which is the weight measurement method, condensation method, and three psychrometer, and the moisture content of the flue gas is typically in the volume percent of water vapor in the flue gas content to represent. If dark gravimetry, need to use hygroscopic agent, the hygroscopic agent used is calcium chloride, calcium oxide, silica gel, alumina, phosphorus pentoxide, magnesium perchlorate and the like.
