Steam boiler wear and electric test pump DSY Henan fast boiler's china dzl chain grate coal fired steam boiler small series with you about wear and DSY electric test pump wear is one common steam boiler heating surface defects, boiler heating surface is arranged in the boiler the furnace and the flue, in particular a heating surface in the steam boiler flue vertical tail, by the long brush smoke, soot in the flue gas so that the wall heating surface wear thinned, so that heat from the flue gas scouring wall ironed a phenomenon known as wear and tear. Flow rate, the concentration of soot in the flue gas and the hardness of the tube bundle arrangement such factors as the wear rate of the heating surface of the steam boiler and the flue gas is related to the flow rate of flue gas wherein the greatest impact on the wear of the heating surface. Experimentally measured, proportional to the cube of the wear rate of the heating surface tubes and the flue gas velocity, it is necessary to effectively control the flow rate of flue gas. Leakage of the furnace wall, a partial wall flue ash, convection heating surface partially severe slagging will cause a partial flue gas velocity is too large, so that the heating surface tubes local wear increased, further, when the soot blowers work failure, high pressure steam steam heating surface tube will blow erosion, so that the wall thinning. Heating surface tubes often wear area is: cool ash, burner, bullnose, and close to Manhole sootblowing waterwall tube aperture; a lower portion of the flue gas before the steering tube heating surface vertical chamber; vertical tail horizontal heating surface portion of the second row of three tubes of the flue, the lower portion of the second three tubes, tube support edge portion of the clip, close to the furnace wall side of the rows of tubes and the individual tubes and the like projecting tube rows. Heating surface wear reduction methods are: to reduce boiler load, reducing flue gas velocity; burning coal quality, reducing the content of fly ash in the boiler flue gas steam; change bundle arrangement, a staggered arrangement to the line arrangement; Clear slagging and blocking flue ash, flue gas flow area increases; leakage reduction furnace wall; the installation of a shoe or the spoiler like. Abrasion test on the electric pump plunger hole set DSY electric test checking pump plunger sleeve (1) Check the DSY type. If the pump DSY electric test has passed the test on sealing ST-990 or the tester 3,375,375, the plunger sleeve is available. If the leakage is large, it is necessary to replace the plunger and plunger sleeve. (2) using the burr, coke, and high-expansion magnifying glass to check the amount of deformation of the bore. When the metering orifice is damaged, DSY i.e. electric test pump is not working properly. Do not attempt to clean with a wire, plug, etc., should be cleaned with a solvent. (3) Check the fuel oil channel as well as choking loose plunger sleeve for cracks. (4) Check DSY electric test pump plunger sleeve surface endless belt black area and Degree how damage flatness.

To reduce the total coal consumption, reduce air pollutant emissions, Guigang Municipal People's Government announced the latest "2019 Guigang tackling air pollution control plan" proposed scheme: Guigang City is actively taking measures to reduce coal comprehensive use of renewable energy , natural gas, electricity and other energy alternatives to coal consumption, reduce the proportion of coal consumption, focusing on reducing the total non-electric coal consumption. New coal projects to implement alternative coal reduction, the implementation of inventory management, so that statistics can be verified.
Details are as follows.
First, the implementation of the total coal consumption control. Take measures to reduce overall coal, renewable energy, natural gas, electricity and other energy alternatives to coal consumption, reduce the proportion of coal consumption, focusing on reducing the total non-electric coal consumption. New coal projects to implement alternative coal reduction, the implementation of inventory management, so that statistics can be verified. October 2018 in conjunction with the regional government Council issued the "Guangxi county industrial park planning and adjustment plan" and other industrial park planning and implementation of the adjustment, the promotion of industrial parks to carry out "an area a heat source" upgrade, encourage 300,000 kilowatts or more coal-fired heating unit carried out the transformation in cogeneration planning guidance to promote the backward small coal-fired and coal-fired thermoelectric heat within the range of (biomass) integrated boiler shut down.
Second, accelerate the comprehensive improvement of backward small boilers. According to the State Administration of Work Market and three ministries "on the strengthening of energy-saving environmental protection boiler" (National City Supervisor ad hoc  No. 227) requirements to promote energy efficient boiler environmental protection, energy-saving environmental protection to promote the transformation of boilers, eliminate backward boiler. Coal-fired boilers built-up area to carry out an intensive investigation, the investigation out of the coal-fired boilers to register one by one, to establish accounting and inventory management, according to local conditions, Take Measures to develop small boiler (10 tons of steam per hour and below) Integrated remediation plan, the classification proposed remediation requirements, before the end of May 2019, the Municipal environmental Protection Bureau for the record. Carry out a comprehensive district built 10 tons of steam per hour and small coal-fired boilers out of work, according to the law to increase efforts to eliminate small coal-fired boilers in accordance with regulations, in 2019 the completion of small coal-fired boilers out of the task; all kinds of more than 10 tons of steam coal boiler strengthen environmental law enforcement supervision, strict implementation of emission standards for boilers that can not be stable discharge standards, shall order rectification according to law, after rectification still do not meet the requirements, shall not continue to use; to strengthen environmental law enforcement supervision of biomass boilers, in particular to strengthen regulatory biomass boiler ban on high-pollution fuel combustion zone of the city; biomass boilers boiler should be dedicated, efficient dust bags and other supporting facilities, prohibit blended with other fuels such as coal. The city and county-level cities above the built-up area in principle, to create a new 35 tons of steam per hour of coal-fired boilers and other regions in principle no longer new 10 tons of steam per hour and below the coal-fired boilers.
Coal fired boiler design features:
1.By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.
2.Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.
3.Both of the front and the back arches of the 10t/h series coal fired boiler design adopt mason work of water cool tubes wall structure, which can form permanent arches.
4.Separate adjustable wind chambers. Wind is feed from two sides. It adopts new type crank screw wind adjustment structure, so that the wind adjustment and ventilation cross section proportion is 100%, which can ensure the easy wind adjustment and make it symmetrically.
5.There is push-pull damper dust removal equipment. The damper adopt finish machining cast iron seal structure, thus the secondary combustion distortion and air leaking in the grate is effectively prevented.
Hot water boiler and a traditional old-fashioned coal-fired boiler is how to deal with water shortages? Machine in use for some time there will be this or that problem, a serious delay the progress of work, causing great inconvenience to the people, such as water shortages, the question arises, hot water boilers and water shortage in the traditional old-fashioned coal-fired boilers It is how to deal with? Electric china dzl chain grate coal fired steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
