stainless steel demister pad for boiler
Bagasse CFB stainless steel demister pad for boiler range
CFB boiler for bagasse: its capacity ranges from 20t/h to 300t/h, steam pressure varies from middle pressure sub-high pressure to high pressure. Among them, middle pressure and middle temperature boiler,which capacity is 75t/h. ZG boiler supply Chain grate type bagasse boiler, bagasse fired CFB boiler, bagasse power plant boiler. Bagasse cfb boiler equipment is common in the sugar processing industry.
What principle of stainless steel demister pad for boiler water level gauge boiler water level gauge that? It is used to determine the water level in the boiler. There are many boiler water level gauge, to introduce the following several common: 1, color water level gauge. For local display drum water level, it is the most widely used in situ water level. Shape is a vertical glass tube, the vapor space is connected to the upper and lower space and the water drum respectively, using the principle of U-shaped tubes communicate with the water level display, the optical properties of the material, water vapor using two portions are presented two colors green to red, to facilitate observation . Color level gauge reliable, intuitive display, may be connected to the control room through the camera, it is an ideal boiler water level gauge. But note that periodic flushing, and some ones short lamp life, need frequent replacement; 2, a magnetic level gauge. Are vertical pipes, there is a magnetic float, the tube arranged on both sides of many small magnetic body, when the water level changes, the float up and down movement drive, since the drive action of the magnetic poles inverted, both surfaces of the magnetic brush in different colors display water level. Common are white, red, green and red. HOWEVER, strictly speaking, a magnetic level gauge flap not appear directly in the drum water level, it is not used, a lower temperature and pressure in the boiler hot water boiler still employed, also a local display. Magnetic level gauge used more reliable, more intuitive display. However, when using the green red magnetic material, such as plant during normal incandescent lighting and low light observation is not clear enough. In addition, some manufacturers of products used for a period of time, the float will be stuck. Thus to be noted that regular cleaning; 3, electrical contact level gauge. Remote use. Sequentially arranged in the vertical direction a plurality of electrodes electrically inter-stage water level will be turned on or off to display the water level. Electrical contact level gauge indication accuracy, especially when starting and shutdown load fluctuations, should primarily electrical contacts and a display color prevail. But to pay attention to the isolation cook stove will damage; 4, balanced dual chamber container. Such displayed when starting the furnace and load fluctuation error is large, not too much explained.
Recently, the Tianjin Beichen District issued a "Tianjin Beichen District in 2019 to win the Battle of Blue Sky battle plan" (hereinafter referred to as "Plan"). "Plan" put forward: to strictly control new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants. Complete the transformation of low nitrogen gas-fired stainless steel demister pad for boiler more than four before the end of September 2019.
Details are as follows.
1, reducing the total coal consumption in 2019, the region's total coal consumption and coal in primary energy requirements meet the relevant indicators. Strict control of new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants.
2, ongoing heating, agricultural, industrial and commercial management of coal-fired boilers, coal-fired boilers to burn consolidate shut down rectification results to ensure that no rebound. Carry out special rectification coal, coal supervision prominence to the implementation of high-quality coal supply and security, supervision and management of coal enterprises to establish a purchase and sale accounting, prohibit the sale of low-quality coal does not meet the requirements of state and city, by increasing the sampling frequency, strengthen information disclosure, strict qualification management, according to the law firm did not check other means, to crack down on low-quality coal to maintain circulation, sale and use of high-pressure situation. Ongoing heating season heating companies burning coal quality inspection. Strictly implement the relevant requirements of the city, set up to ensure that the region is no longer operating coal storage space, strengthen supervision.
3, to promote the safe and orderly clean warm winter residents. The completion of the outer ring 23 000 residents in rural areas "coal to electricity," the task before the end of October 2019, the region's urban and rural residents to achieve bulk coal for heating, "cleared."
4, before the end of September 2019 to complete the transformation of more than four low-nitrogen gas boiler. The full implementation of leak detection and repair (LDAR) system. Ensure the region involving volatile organic compounds emissions from industrial enterprises and supporting environmental protection facilities full coverage, stable and meet the relevant emission standards.
Furnace explosion of the causes of ordinary gas stainless steel demister pad for boiler steam boiler gas burned in open flame and furnace process, if the following three conditions appear, it is easy to attack blast furnace accident. 1, open burning furnace, furnace residual gas content limit to reach the fire. 2, open incinerator, several points Eventually, the content of the furnace gas reaches the ignition limit, and then incinerated. 3, halfway flameout, fuel discharge series, spontaneous combustion of the fuel in the furnace temperature can change, so that the gas reaches the ignition limit of the content, and then incinerated. Forming flame halfway reasons are as follows: 1, gas is not supplied in succession. 2, during the adjustment, the valve opening degree increases or decreases suddenly. 3, lean fuel-rich flammability limit narrow. In order to avoid the onset of blasting incidents of burning fuel gas-fired boiler initiative and flame monitoring protection devices should be installed.
