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 automatic 1mw industrial 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.
What is different from the automatic 1mw industrial hot water boiler and steam boiler there? There are many companies will operate on steam boilers do this relatively high cost of care. After the scene since the late boiler equipment, equipment up and running is a big sum of costs. About enterprise, if choose for their own fuel boilers, boiler fuel efficiency will make use of further progress. Therefore, we demand that the cost of running on several different fuel steam boilers budget to know. Gas: Advantages: clean energy, high thermal efficiency, low cost. Disadvantages: gas adapter constrained condition. Produce one ton of steam costs about 240 yuan (gas prices by 3 yuan / square meter accounting). Fuel: Advantages: no pollution, high efficiency, no fuel constraints. Disadvantages: higher operating costs. About 594 yuan one ton of steam production costs (fuel prices accounted for 9.0 yuan / kg). Electric heating: advantages: no pollution and no fuel constraints. Disadvantages: is a secondary energy, high operating costs, the cost of producing one ton of steam is about 700 yuan (price 1 yuan / degree). Coal: Characteristics: low operating costs. Disadvantages: severe pollution in some areas, the use of restraints, cost of production of one ton of steam is about 150 yuan (coal prices by 1,000 yuan / ton accounting). Heat boiler is an important means to transfer heat to the appropriate fuel equipment, it is now being widely used in industrial production and heating and so on. Popular in the size of the boiler is a steam boiler and hot water boiler both types, many people who only know the boiler heating equipment, but can not tell in detail parting boiler. Today we gave Shandong steam boiler explain what the differences steam boilers and hot water boilers, after all, what! On the surface, we can understand heating hot water boilers and steam boiler heating method chosen is not the same, but the distance between the hot water boiler and steam boiler Moreover, detailed in what areas? The different output media we literally can be seen, the medium is hot water output from the boiler, medium boiler steam output of the steam. First, the user can according to their demand for the output media, choose the appropriate boiler. Different steam boiler space occupied by a high pressure vessel, through steam forming water is heated after the completion of the vapor compression heating, and the area of the pressure vessel by the use of less water boiler is an unpressurized vessel by virtue of heat temperature of the water to complete the heating, hot water boilers professional usually occupied by a larger location, but better able to complete the non-selection of the pressure vessel safety are better able to ensure the safety of those who use. Because the size of different heating and heat storage capacity of water vapor from a large, high-volume hot water boiler and thus be able to choose long-distance transport of heat pump delivery lost less able to complete large-scale transport of hot water requirements. The steam boiler because the steam freezes faster, so in the long-distance transport can lead to sudden drop in water temperature, so the size of two kinds of heat supply boiler equipment can withstand different. Heating steam boiler at different speeds when using the heat generated as the water transpiration and thus burn calories in order to ensure the needs of large steam generation, and thus the temperature rise faster fever faster speed; hot water boiler heated water to ensure that the temperature of the water in the use of Yung heat better, thus better able to maintain the heating heat.
Boiler manufacturers tell you how maintenance of the gas boiler?
