Steam boiler accident type and processing method, and use common sense safety boiler new biomass coal burning competitive price steam boiler accident type and processing method, overpressure accident 1 boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over " red line "safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
Auxiliary means configuration of the auxiliary boiler apparatus comprising a boiler fuel supply means, air blowing means, the wind means, water supply means, means ash, dust removal device, instrumentation, valves and other automatic control device. Today small to introduce a boiler with auxiliary devices. A boiler fuel supply role is to store, transport, supply of the fuel. There are coal, to the media devices (mill, of mill, and coarse powder separator and lose powder duct), and supply means (for the fuel heater and the like), a gas supply device and the like. Air blowing means which effect a treasure ah blower and duct, the grinding media and air into the furnace through the air preheater apparatus. Blower apparatus, comprising a draft fan and the smokestack, speaking furnace flue gas to exclude air sent. Water supply means comprises a water tank, water supply pipes and water treatment equipment, boiler feed water away. In addition to ash means ash comprising artificial addition, other mechanical ash, ash in addition to water, in addition to the negative pressure pneumatic ash, soot blowers, and other field ash, ash from the boiler and out away. Dust removing device, which includes a variety of dust action of gravity, inertial force, centrifugal force, washing bar-type, sound wave, filtering, static electricity, etc., fly ash out of the boiler flue gas, to protect the environment. Instruments, automatic control devices and valves, including the role of pressure gauge, a thermometer, a water level gauge, the alarm level, the relief valve, water meter, steam flow meter, pressure meter, indicating the exhaust of carbon dioxide and other instruments, a steam valve, a valve, a check valve, like the valve discharge valve, and automatic detection, automatic protection, control and automatic adjustment and automatic computer control means. The boiler more safe, economical operation. These are the auxiliary device structure of the boiler, I believe you must have learned a lot of knowledge of it, I hope this helps you make better use of boiler equipment.
Gas-fired steam boiler in the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work.
4. Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use, and does not produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.
Recently, Xuzhou City ushered in the good weather blue sky, sweetness and light, a set of numbers from the Xuzhou municipal environmental protection department made us confident to bring back the blue sky. According to the latest air quality in the province informed that this year, two good days in Xuzhou City 73 days, an increase over last year eight days; PM2.5 concentration of 78μg / m³, the concentration of upward momentum have been effectively curbed. The atmosphere improving governance has achieved victory.
Since April this year, Xuzhou municipal government set up the city's Operations Command prevention tackling air pollution, and the establishment of 16 specialized working groups in accordance with the classification of remediation tasks, the relevant departments to deploy officers to concentrate on work, concentrate on promoting the prevention and control of air pollution crucial action. At the same time, Xuzhou developed and issued in the history of the most aggressive, the most comprehensive measure of the "Xuzhou City in 2018 tackling air pollution control program," the task of governance engineering, project oriented, technology node.
First, action aimed at the city's 13,654 "messy dirty" business, and sort of closure to ban or stop crime measures. "Coal-burning pollution" key problem is the political commissar of the governance of Xuzhou City, after the operation began, to more than 10 tons of steam coal-fired boilers implementation of classification regulation, the city's 18 coal-fired thermal power companies implement flue gas treatment project off white, investigate and shut down downtown bulk coal processing operations point 171, for 22 coal-fired power companies and the city's 11 coal production (including coal washing) enterprises in high frequency sampling.
Furniture, printing and dyeing, filling stations and other industries, focusing on pollution VOCs special inspection work, check the company focused on source control, process management, end of treatment, the treatment facilities to ensure the normal operation of equipment, environmental protection do not have the processing power of enterprise firm shall be eliminated by shutting down.
