In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired condenser boiler flue condenser boiler flues governance as a key task to be mentioned again. Meeting specific targets: by 2019, Harbin will govern coal-fired boilers, boiler out of 35 tons and below do not have to upgrade conditions, starting 65 tons or more of coal-fired boilers and energy-saving ultra-low emissions transformation.

2019, Harbin will continue to strictly control the total amount and quality of coal, according to local conditions to solve the shanty towns, suburban town (township) village coal powder burning problem by briquetting, Burying to field, the way raw material cogeneration, effective path to explore the comprehensive utilization of straw, the straw open-air Jinshao continue to focus on the work to implement the required emission limits industrial emissions, car exhaust strengthen, kitchen fumes, dust and other site management, effectively improve air quality.

2018, Harbin City, air pollution, elimination of coal-fired boilers 1191 units, biomass boilers to replace more than 10,000 units, updated bi-fuel taxi 1270 units, 1323 units of new energy buses, comprehensive utilization of straw and prohibiting open-air work strength forward, ambient air quality fine days up to 312 days, an increase of 42 days over the previous year, the highest level since the ultra-high PM2.5 monitoring.

Comparison of advantages and disadvantages of making process of Boiler Feed Water treatment equipment

At present, the processes for preparing ultra-pure water in the power boiler feed water system are basically the above three, and the rest of the process flow is mostly derived from different combinations and combinations on the basis of the above three basic process flows. Their advantages and disadvantages are listed below:

1. The first type of ion exchange resin has the advantages of less initial investment and less occupation, but the disadvantage is that it requires frequent ion regeneration, consumes a large amount of acid and alkali, and is destructive to the environment.

2. The second type uses a two-stage reverse osmosis device, which is characterized by a higher initial injection rate than an ion exchange resin method, but does not require resin regeneration. The disadvantage is that the relevant membrane originals need to be cleaned or replaced regularly, and the water quality is relatively not too high, and most of them can only be about 1 us/cm.

3. The third type uses reverse osmosis for pretreatment and is equipped with an electric deionization (EDI) device. This is the most economical and environmentally friendly ultrapure water preparation process for preparing ultrapure water. It does not require regeneration with acid and alkali. It can continuously produce ultrapure water, which is not destructive to the environment. The disadvantage is that the initial investment is too expensive compared to the above two methods.

Steam condenser boiler flue condenser boiler flue in Henan natural circulation pump and clean fast boiler's steam boiler Xiao Bian told you about in the natural circulation pump and clean natural circulation boiler is the use of the density difference circulation loop rise and fall pipe soda mixture with water in the pipe to establish the working fluid cycle. Having a drum, a radiation heating surface, convection heating surface and a button connected to a steam boiler, a steam separator, and a larger heat storage capacity of water, more reliable water cycle, water separation was also better. But the drum heat capacity, simple wall thickness, temperature, and speed limits start and stop the boiler drum manufacturing, transportation and installation is also more difficult. Natural circulation boiler further includes two types: a steam boiler, and such a boiler is divided into: 1) Simple cycle: on the drum, the downcomer, the lower header tank or drum, and also some of the riser pipe constructed in parallel there are upper header. 2) Complex cycle: different conditions riser group consisting of linked together by common circulation circuit member. Two hot water boiler in the natural cycle further includes the following three: 1) the whole natural circulation: In addition to an outer surface heating radiation, convection heating surface are all working according to the natural circulation, the use of heating surface bundle structure. 2) Natural circulation predominant: radiation heating convection heating surface area for the most natural circulation, convection heating surface portions of the work by directly using serpentine configuration. 3) semi-natural circulation type: radiation heating surface is natural circulation, convection heating surface by all DC operation, serpentine tube means. Natural circulation boiler For ultra high pressure steam boiler or less, more subcritical pressure employed, but the soda density difference decreases, weakening the flow head, high purification of the steam separator and steam requirements, the highest pressure of 17.3 MPa, the capacity to 2350t / h. Oil cleanliness have a significant impact on the life of the hydraulic pump, in addition to the requirements set forth above, the user must also pay special attention to the following points: 1, must be fuel tanks, pipes, hydraulic cylinders and hydraulic before installing, commissioning clean valves, etc., of the oil must be filtered oil vehicle when filling new oil to the tank, to prevent the contamination caused by the dirty barrel of oil. 2, must be prevented during transport, since the disassembly packing conduit pipe caused by contamination, and the tank element. Thus, hydraulic oil tank and other devices as far as possible the overall packaging system, as few as possible detached pipe, tubing and fittings must be disassembled at all sealed with a dust. 3, the new pump one week after use, the need to once all the oil filter, oil and the oil filter and washed, and then according to machine work load situation 3 to 6 months to replace a fluid, a cleaning tank. 4, during use of the system is prohibited due to heat generation and the injection hole or opening the fuel tank cap.
