Since March, Harbin City Bureau of ecological environment began to organize special supervision to carry out coal-fired boiler enforcement issues, 309 sets of unfinished mention boiler and marked the transformation of the city after the 2018 boiler to mention 409 logo revamping supervise enforcement actions taken joint law enforcement and the monitoring center the way, as has been completed, the list of Wuchang city, Bayan, Mulan, Tonghe County, Yilan County, Founder county business checks on double Harbin city.
After steering group went to Harbin City, district, county (city), by reporting to listen territorial ecological Environment Agency and the inspection unit, a preliminary understanding of corporate profiles, boilers, pollution control facilities and pollution-line monitoring equipment on-site supervision and inspection, found the three groups of coverage and is not completely blocked, businesses can not provide the proposed supervisory monitoring data reports or third-party monitoring data report corrections and comments, requirements of territorial ecological Bureau to investigate and punish.
The special supervision and inspection work time, heavy task, environmental inspectors and monitoring to front-line staff in site supervision, to overcome the difficulties, give full play to law enforcement officers proficient in professional knowledge and rich practical experience and other advantages, the successful completion of stage special inspection of law enforcement tasks.
Gas-fired boiler coal steam boiler in textile industry, gas steam boiler buy several natural gas boiler should pay attention to, the purchase of natural gas boilers points to note from the National Development and Reform Commission learned that China's coal to gas steam boiler is widespread promotion of the implementation, will enter a stage of comprehensive reform. Xinjiang is about to be the most important work to complete the rectification, the rectification process of the Central Plains and northern regions also increased the intensity and speed of more than 40% of the coal-fired steam boilers, gas-fired completed the replacement of the country. At this stage there are a lot of users need to buy gas-fired boilers to meet the current national environmental policy, I would buy natural gas boiler problems and the majority of users to exchange views in order to buy the rest assured, with satisfaction. First and foremost do with the current coal-fired steam boiler model number and tonnage, boiler gas production and steam pressure that is being used enough, if we can current production, gas production and pressure on the election of equal size gas steam boiler, if not enough or barely enough, you need to choose a slightly larger model of boiler is the second point you are ready or the near future to expand the scale of production, it is necessary to recalculate gas production gas steam boiler, steam boiler of the gas production and future production scale be able to adapt. I met a lot of friends only consider the current, do not consider the needs of the next few years, thinking only meet the current needs on the line, such as the expansion of production and back. The ideas and practices to create a lot of trouble later, the life of a gas steam boiler is probably about 15, you do not have to change a few years, it is only used when processing a lot of losses. Furthermore, the replacement process is very time-consuming, to re-install the application procedures go again, and delayed production. Do not take precautions, you will regret it. The last thing to note is to ensure that the opening of the gas pipeline, if your area has no natural gas pipeline, is to buy a gas steam boiler also spend the. In determining the purchase of gas-fired, the first not to rush to the boiler transported to the site, first opened gas pipeline things well. A client told me: "I opened a mouth, a natural gas company gave me to do 100,000 a month just to run." So, first hit the point about the relationship, try to spend less money to natural gas mouth opened, then natural gas boiler shipped home.
How many calories Horizontal one ton boiler coal steam boiler in textile industry needs? 1 ton steam boiler, require 600,000 calories, biomass is the most economical fuel. 1 t of steam boilers, 600,000 calories needed, is converted into fuels: diesel 58kg / hour, i.e. cost of diesel and 466 / hour; biomass particles 150kg / hour, the cost of 165 / hour. 697 electrical degrees / hour, i.e. cost of electricity 697 / hour; gas 75m3 / hour, i.e. cost of natural gas 375 / hour; 120kg of coal / hour, i.e. cost of coal is about $ 120. As can be seen from the above, coal and biomass particles are the most economical. Wherein the combustion of coal is difficult to control, and the actual consumption costs considerably biomass particles. However, polluting coal boiler is very large, and the biomass boiler is both economical, and environmentally friendly. Accordingly, we can see that biomass pellet boiler is the best future direction of development of the industry boiler, the boiler will also become the industry mainstream.
Shutdown four tons of gas boiler boiler coal steam boiler in textile industry shutdown and maintenance of fire into pressure shutdown, normal shutdown, emergency shutdown. A pressure fire fire shutdown shutdown pressure applied to temporarily stop the supply of steam, the boiler is shutdown pressure hot standby state. 1, before the pressure reduction appropriately to fire the boiler load, and according to the length of the seam thicker shutdown time, (up to 200mm) to accelerate the speed of the grate, the grate is stopped when rotated about 1.5 meters from the coal seam to the shutter. 2, stop blowers, blower suitably adjusted flap subsections, relying on a lean-burn natural ventilation is maintained. 3, the sewage, to allow the water level in the boiler water level. 4, Yang fire regularly, to prevent rotation of the furnace grate extinguish the fire bed. Young fire first before sewage water, then rinse water level gauge. II. Normal shutdown Normal shutdown for heating period ends, boiler pour fire into the buck repair or maintenance. 1, make a record before shutdown problems in operation, so that after the shutdown process. 2, the coal bucket coal memory runs out, the amount of toner to reduce the wind. 3. Stop the blower, draft fan stop and then the opened door grate ash. 4, after the steam supply is stopped out, the boiler to the boiler water to maintain a high level. 5, close the main steam valve, if the pressure rises to open the air exhaust valve suitable pressure relief. 6, stop the water supply to the boiler and economizer attention to monitoring changes in water temperature, open return pipe if necessary. 7, 4 to 6 hours after the furnace fire bed down exhausted, continued rotation of the cooling grate. Throughout the boiler throttle, the door should be kept closed. Allowed to naturally cool. 8, appropriate to open the pump, the boiler water and sewage. When the pressure drops to zero, open the air valve. 9, when the boiler water temperature is below 70 ℃, boiler water can be exhausted. Shutdown is complete. 10, less than 24 hours during shutdown. Avoid Shutdown cooling process, step-down too fast. Third, emergency shutdown emergency shutdown applies to the boiler accident, g combustion equipment damage, furnace or boiler structure collapsed wall is red-hot, a serious threat to the safe operation of the boiler when; h boiler pressure parts found serious distortion, leakage. when i found flue gas explosion or secondary combustion, boiler and seriously endanger the safety of operating personnel;; when endanger the safety of operation.. the safe operation of the boiler j endanger other unusual circumstances when. 2, the emergency shutdown procedures to immediately stop a blowing coal and reduce the wind; B rotates quickly grate, the pour slag pit coal or sand, wet ash coal burning fire to extinguish. , but not to the firebox water;. c boiler air valve, the relief valve opens quickly exhaust the steam pressure is reduced;. d after the fire goes out, stopping fan, opening the ash door and door, promote air circulation accelerated cooling; 3, emergency shutdown Notes a. when an accident and emergency shutdown due to lack of water, boiler feed water is strictly prohibited to, and shall not be such as to open the air valve or exhaust valve work on preventing boiler from sudden changes in temperature or pressure to expand accidents;. b when filled with water due to an accident and emergency shutdown, should immediately stop the water supply, reduce combustion, open the drain valve and drain, due to lower the water level, while opening the main steam pipe, the sub-cylinder and steam traps mother tube, water and prevent steam pipe with a large number of water hammer occurs. c. emergency shutdown operation to ensure the safety of the main event of an accident to calmly deal with, timely reporting, and make relevant records in the "log table boiler." d. Whether shutdown any case, we must maintain timely contact with steam departments.
