Fangkuai traveling grate thermax boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. 1, why chemical cleaning of newly installed and overhauled boilers? In the process of manufacture, transportation, installation and maintenance of boiler, it is inevitable that some impurities such as dirt, iron chips, welding slag, iron oxide and so on will be produced and glued to the pressure parts of the steam and water system in the process of manufacture, transportation, installation and maintenance. As soon as these impurities enter the steam-water system in operation, they will do great harm to the boilers and steam turbines. Therefore, the boilers before they are installed and overhauled must be chemically cleaned to remove them. 2. What are the rules for the time and temperature of water supply before boiler start-up? Why? The inlet speed of boiler before start-up should not be too fast, usually no less than 4 hours in winter, 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet water temperature of a cold boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. The inlet water temperature of the uncooled boiler can be compared with the drum wall temperature, and the general difference should be controlled within 40 ℃, otherwise the inlet water speed should be slowed down. The main reasons are as follows: (1) because the drum wall is thicker and the expansion is slow, the tube wall connected to the drum wall is thinner and the expansion is faster. If the inlet temperature is too high or the inlet speed is too fast, it will cause unevenness of expansion, crack of welding joint and damage of equipment. (2) when the feed water enters the drum, it always contacts the lower wall of the drum first. If the difference between the feed water temperature and the drum wall temperature is too large, the speed of entering water is fast, the upper and lower walls of the drum and the inner and outer walls will produce a larger expansion difference. Cause large additional stress to steam drum, cause steam drum deformation, produce crack 3 when serious, how does the low temperature corrosion of tail heated surface produce? Formation of SO2,SO2 from sulfur Combustion in fuel combined with oxygen in flue Gas to form SO3, when the temperature of the heating surface is lower than the dew point of the flue gas The steam in flue gas is combined with SO3 to form sulphuric acid steam, which condenses on the heated surface and results in low temperature corrosion of the heated surface. The cold end of air preheater is prone to low temperature corrosion. 4, when the emergency shutdown? (1) when the drum water level exceeds the limit. (2) when all water level gauges of the boiler are damaged. (3) explosion of superheated steam pipeline, reheated steam pipeline and main water supply pipeline. (4) when reburning occurs at the end of the boiler. (5) all suction, fan and air preheater stop operation. (6) when reheating steam is interrupted. (7) Boiler pressure rises to safe door operating pressure, and all When the safety door refuses to move. (8) when an explosion occurs in the furnace or in the flue causing serious damage to the equipment. (9) when a boiler extinguishes a fire. (10) when a fire breaks out in the boiler room, it will directly affect the safe operation of the boiler. (11) when the furnace tube blasting cannot maintain the normal water level of the drum. (12) when all operator stations are blackscreen or crash at the same time and the main parameters are out of control. 5, how do I flush the drum water level meter? There are three processes for flushing the water level gauge: water side flushing: opening the drain gate, closing the steam side door, opening the water side door; steam side flushing: opening the discharge door, closing the water side door, opening the steam side door; Open the discharge door, open the steam side door, open the water side door. Rinse and close the drain door.

Henan has 2 tons of gas hot water traveling grate thermax boiler manufacturers what? Henan 2 tons of gas hot water boiler manufacturers what? With the boiler gradually open up the market, large and small boiler manufacturers have been slowly emerging from two tons of gas hot water boiler manufacturers are also countless. If we have the intention to purchase two tons of gas hot water boiler, then the choice of the manufacturer should be carefully considered. (1) In view of this sale and installation of boiler manufacturers qualifications meets the requirements of the relevant units. (2) In view of this factory boiler production technology, production processes, boiler and accessories for material selection based on whether or not the national standard. (3) In consideration of this quality manufacturers of boilers, this factor can be understood in terms of a simple case made by manufacturers in the past as well as its reputation and so on. (4) Taking into account the focus parameter index in the actual operation of the boiler in the unit at the same time if you can save energy, bring us higher value and lower operating costs. In short, Henan manufacturers have two tons of gas hot water boiler are many, but is suitable for our specific needs, we need to carry out strict checks of. What maintenance and corrosion protection hot water boiler is

In response to the call of the State Environmental Protection Department, to further improve air quality, enhance people's happiness blue sky, located in Leshan City, Sichuan Province of the energy restructuring and clean coal-fired traveling grate thermax boiler as the primary task of air pollution control, to promote the elimination of coal-fired boilers remediation work. According to statistics, from January to October this year, Leshan City, the main urban air quality index improved 11.86 percent year on year, a figure that ranked third in the province; a few good days of 251 days, an increase of 29 days, compliance rate of 82.57%; PM2.5 average concentration of 44.5 micrograms / cubic meter, an improvement of 14.09%; PM10 average concentration of 69.0 micrograms / cubic meter, an improvement of 5.74%. Improve these figures can not be separated Leshan Municipal People's Government's strong support and initiatives. Leshan municipal government adhere to precise planning, but also a public green, clean living environment.

A careful planning. Since 2017, vigorously promote energy restructuring and transformation of coal-fired boilers, in-depth investigation status of the city's coal-fired boilers, having accurate number of the city's coal-fired boilers, steam tonnage and treatment facilities, the establishment of coal-fired boilers ledger. To promote the implementation of the "coal to electricity", "coal to gas" projects the city's key industries, coal-fired boilers to transform, adjust the expansion of high-pollution fuel combustion zone ban.

Second, the fine classification. Classification of coal-fired boilers to carry out renovation work, from the source strict control of new coal-fired boiler, new and expansion projects to encourage the use of electricity, natural gas and other clean energy; with the implementation of small coal-fired boilers eliminated, medium and large transformation. The city 10 steam tons / hour or less and a total of 717 small coal-fired boiler units are all clear, a total of 1030 tons of steam. Medium-sized coal-fired boiler clean energy transformation or transformation in accordance with the deadline for ultra-low emission "should gas is gas, should the electric power" principle, Taiwan is currently the city's 44 large and medium sized coal-fired boiler clean energy transformation has been completed and ultra-low emissions transformation.

Third, the precise advance. Strengthening full control of behind schedule inspectors to speed up reform. Strengthen financial subsidies, to boost the progress of work, more than 7 million arrange special funds for the transformation of the atmosphere and medium-sized coal-fired boiler subsidy, cities, counties (cities, districts) to finance 20 steam tons / hour and clean energy alternative to coal-fired boilers the implementation of special subsidies.

Plantation economy is the main economy type in Sri Lanka,the main crops are tea, rubber,coconut and rice.So biomass fuel is rich for industrial traveling grate thermax boiler.Sri Lanka’s biggest advantage is the mining and geographic location,besides,textile industry and tea factory although in the early development,they are also popular in the uropean market.Industrial boiler can produce the steam or hot water for the textile and tea industry,so industrial boiler have market space in Sri Lanka.
