After the steam fire tube boiler sketch to produce steam also need to pay attention to them? Steam boilers purpose is to generate steam to conduct heat, but when the steam produced by the boiler equipment should not be on the matter, or to pay more attention after the steam, because this time the steam boiler will start boost, while furnace the saturation temperature of the water also began to increase. Since the temperature of the water in the rising steam boilers, gas bubbles and metal evaporation heating surface wall temperature also began to rise at any time, need to pay attention to thermal expansion and the temperature of thermal stress, because the bubble wall thickness is thick, the main heating process in the boiler the problem is thermal stress. At the same time, but also consider the overall thermal expansion problems, especially for pipe heating surface of the steam boiler because the wall thickness, length of problems in the heating process is thermally integrated for expansion, but also pay attention to thermal stresses, to prevent neglect caused the failure. Generating steam in a steam boiler and boost heating process, the temperature difference between the bubble there is a temperature difference along the thickness of the vertical wall and, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall surface temperature is above the lower case, in order to prevent excessive thermal stress, the boiler must be slow step. The steam boiler ignition during bootstrapping, the operating state of the steam parameters of the boiler, the water level and the respective members is constantly changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, be sure to arrange professional staff to closely monitor a variety of changes in the meter indication. By adjusting the control pressure, some of the process parameters of temperature, the normal water level in the range of the allowable, but also the reliability of the assessment, a variety of security instruments, valves and other components, so as to ensure adequate safety and stable operation of the steam boiler . The higher pressure steam boiler, energy consumption will be higher and higher, the corresponding steam pressure equipment and piping, and the valve will also increase accepted, which also makes maintenance protection boiler steam demand is relatively increased, and steam generated in the heat generation and transport processes and also increase the proportion wandered. High pressure steam mouth of salt will increase with increasing pressure and that the heated area of the waterwall tubes salt, smoke tubes and the like drum phenomenon generating structure, resulting in overheating foaming, clogging phenomenon, can cause severe pipeline explosion and other dangerous accidents.
Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast fire tube boiler sketch steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
In the traditional concept of the people, the Boilermakers is a job using the boiler units must be staffed, they must not only ensure that the temperature of the boiler operation, but also the boiler safety and maintenance work. Fast boiler gas boiler was produced by highly automated control system, automatic adjustment control boiler operation stability, which is how to achieve it?
How to choose the vertical steam fire tube boiler sketch Currently, many industrial production will select vertical steam boiler to improve production efficiency, but because the boiler is a relatively large-scale production equipment, on their respective purchase costs will be higher, so in the selection shall be bound to uphold a more cautious approach to more cost-effective to buy high-quality boiler, so how companies can choose to do good vertical steam boiler? 1, pay attention to the thermal efficiency of the boiler and the steam vertical steam boiler which time is best to use, have to be judged from the performance of the product, good performance products in the boiler thermal efficiency of the steam out of time and has a unique advantage, the higher thermal efficiency and its future operational costs will be lower, the performance of the product will be more reliable, so only choose the superior performance of vertical steam boiler in order to obtain better results using the shorter the time represents the vapor. 2, depending on sewage capacity of the boiler and the heating area businesses in the purchase vertical steam boiler depends on the availability of sewage capacity, only with a certain self-cleaning inside the boiler, remove the sludge and the ability to reduce the scale of outstanding products will be worth the user selected purchase, secondly, the size of the heated area of the boiler is also the focus of this study, and only choose to large vertical steam boiler heating surface, in order to reduce energy consumption and greater productivity. 3, to consider the brand and price of the boiler vertical steam boiler Which is good reputation, will have to see the product brand and price, when purchasing goods than the boiler to a number of selected products and pay attention to the brand, because brand great product in terms of quality and after-sale protection will be relatively large, in addition, their own business can afford the price is considered the focus, only to pick the price to the boiler equipment within the scope of the investment costs reduce the economic burden on businesses . The above aspects is the company in the selection of vertical steam boiler of the most common and most issues to be considered, so, as long as companies follow these buying tips and essentials, will be able to choose the most suitable for their own production and cost-effective good standing steam boiler products, leading to better use of effects and adapt to more powerful production needs.
