How to protect steam boiler steam boiler steam quality is much broader than the application of hot water boilers, hot water boiler is mainly used for heating and hot water supply and steam boiler applications covering all industrial, power generation and other industries. What usually buy boilers for steam boiler is required? It is undoubtedly the security, stability, high efficiency, long life, cost savings, etc. However, these requirements and are directly or indirectly related to the quality of steam. Quality counts of steam, because it can affect the smooth running of the system, firmly believed, the economy is also related to product quality, production of power and energy consumption. If the steam boiler users should not have given it some attention, certainly will trigger a series of follow-up questions boiler. 1) the presence of rust in the cleanliness of the steam pipe, when the residual carbonate deposits, there may be means slag debris and the sealing material, these impurities have valves, causing jamming equipment damage, the pipeline will increase abrasion. Approach means that the progress of cleanliness pipe filter, and the filter means for level. 2) dryness incorrect boiler feed water treatment, boiler level control of unreasonable and excessive short-term peak load and other factors will lead to a total soda boiler Teng phenomenon, making the boiler outlet boiler with water. When the steam active in the pipeline, the heat pipe will condense part of the steam added to the condensed water pipe. The condensed water with chemicals and other impurities may accumulate on the outer heat transfer equipment, heat exchange equipment impact power, and impurities in the deposited metal outer scarring apparatus, resulting in uneven heating of the metal surface, the number of shortened life. In addition, the presence of water vapor transpiration decreased enthalpy of steam, adding steam consumption; steam in the water will increase the water film thickness measurement of steam heat exchangers appearance, rated thermal resistance occurs. Separators installation progress is useful means of steam quality, efficient steam trap steam quality can progress to 98%. 3) purity of the air will be present in the steam system, since the occurrence of a steam boiler still inevitably contains a small number of air, together with the pipe and equipment will have to start air, system and equipment downtime due to internal vacuum suction air. Air very low thermal conductivity, is a poor conductor of heat. Air containing steam system, the steam will decrease with the production capacity of the equipment, will increase the corrosion of pipes, valves and equipment. System steam exclude non-condensable gases such as air and thus the most useful way means that the progress of the steam purity means and the air in the system. 4) stable pressure / temperature in order to ensure the process heating requirements, steam reaches the point of steam pressure shall demand value. Together, and steam pressure should not be too high, otherwise it will add steam consumption. When the steam contained in the non-condensable gas such as air, although the pressure gauge to show satisfactory, but lower than the temperature corresponding to the temperature corresponding to full. Send high pressure steam, low pressure steam. Into the supply of steam equipment to meet the requirements of a minimum and a stable pressure. This will not only satisfied the needs of production, but also to reach the energy saving effect. Suitable selection of the delivery pressure of the vapor pipe diameter and useful heat piping and valves, plus a reasonable hydrophobic emptying conduit, together with the use of a reduced pressure regulation point, the point can be achieved by vapor pressure / temperature stable.

Recently, the Anyang city government released the 2018 benchmark of scientific and technological innovation of enterprises citation, to be commended and encouraged Anyang nine local enterprises. I company with a solid technology skills, steady pace of development and constantly aggressive determination to win awards municipal government.

Vacuum gas boiler low water level is broken down to produce how to do 1, vacuum gas boiler water level there is not normal. 2, the water level controller has no problem. 3, low water level control tube stuck. 4, China Unicom cylinder tube blockage due to the formation of scale vacuum gas boiler must do what several environmental flow gas boilers | oil-fired boiler |? Environmental Equipment Co., Ltd. steam boiler coal-fired boiler must do desulfurization dust, vacuum gas boiler as long as it has no water purification, treatment? vacuum gas boilers are environmentally friendly facilities, smoke no need other treatment. Involved in water purification, do not know which side are you referring to? Vacuum gas boiler feedwater sure to go through the soft water, avoid vacuum gas boiler scale formation. If the sewage discharge, simply lowering the temperature, the supernatant can be directly discharged. So, vacuum gas boiler without environmental protection facilities.

Related problems of boiler corrosion deactivated 1, deactivate the boiler corrosion damage to the concept of corrosion occurring at the boiler cold standby, hot standby, or during servicing referred to deactivate corrosion. Disable boiler corrosion, primarily because the metal surface is not completely dried during the shutdown and oxygen in the atmosphere continues to leak into the cause. Although the internal and external boiler heating surface corrosion during shutdown occur simultaneously, but internal corrosion is more serious than external corrosion, so corrosion is mainly refers to disable the internal heating surface corrosion. 2, after the cause of corrosion disable shutdown, with decreasing pressure, temperature, boiler water vapor condenses into water, there will be a vacuum inside the boiler, outside air leakage into the furnace, oxygen and moisture vapor case, it is prone to corrosion of metals. Due to the structure of the boiler, if certain measures are not adopted, disabled corrosion is inevitable. Vertical e.g. superheater is not within the water in the superheater drained. When the internal heating surface metal junction with a water-soluble salt scale, will form a high concentration salt solution when it absorbs moisture, so that increased corrosion disabled, and the formation of ulcers corrosion. In this case the inlet of the superheater is often present. Because of the separated saturated steam is always when entering the superheater with a small amount of boiler water, saturated steam into the superheater absorb heat, water is evaporated into steam oven, and the boiler water containing salt is deposited on the inlet tube wall superheater. 3, disable corrosion prevention, mitigation method (1) In order to prevent or mitigate disabled corrosion protection measures should be adopted shutdown. Many shutdown protection methods, mainly divided into two categories: wet and dry protection protection. Wet disable protection commonly used in the short time, for example within one month. Wet common method is to protect the other peroxygen filled in boiler water, or an aqueous solution of alkali, maintaining a pressure of 0.3 ~ 0.5Mpa, to prevent air from leaking into the. (2) If a longer shutdown, or cold weather, in order to prevent freezing equipment, should be protected by a dry method. The method is: After shutdown, the temperature dropped to 70 ~ 80 ℃, the furnace let go all the water, using the water in the boiler will heat the entire heating surface evaporated to dryness, and dried with compressed air furnace without blowing vapor all off-contained anhydrous calcium chloride and then placed in the drum of the container. Per cubic meter of water volume ratio 0.5 ~ 1.0L of calcium chloride was placed (e.g., with lime according to 2kg / m3 basis), then the manhole is closed, periodically checked and found to be replaced when the desiccant into powder. (3) may be filled with nitrogen or ammonia gas charge protection, their preparation and use as a desiccant. Since ammonia is lighter than air, so protection during charging and ammonia, the ammonia gas should enter the upper exhaust air from the lower portion. Nitrogen is slightly lighter than air, can enter the upper portion of nitrogen from the exhaust air from the lower portion. To prevent air from leaking into, the pressure should be maintained 0.3-0.5Mpa, the pressure reduction should replenish ammonia or nitrogen.
