coal fired single drum threaded flue pipe steam boiler

Recently, Nanchang, Jiangxi Province to fully implement the national environmental protection work conference and the province's environmental protection work conference, combined with the actual situation of the city, issued a "blue sky Nanchang win the Battle of three-year action plan (2018-2020 years)" (referred to as " plan"). "Plan" put forward a management plan for major air pollution problems.

As the relevant departments to actively promote the utilization of clean energy. The city gradually reduce the proportion of coal consumption, by 2020, coal accounted for the proportion of energy consumption dropped to below 65%; principles and has gradually increased the proportion of natural gas energy consumption, adhere to "the electric power should", "should air the gas" to promote natural gas work to build the pipeline, steadily "coal to gas" project.

2018, the main city of Nanchang to the new area, the main city area and open small blue through the open area to expand the range of city ban on burning areas. By the end of 2020, Nanchang County, Jinxian, Anyi required scoping combustion zone ban within the jurisdiction of, and informed consent of the uniform implementation of the municipal government.

"Plan" put forward in 2018, the main city of the new areas into the combustion zone ban, the main city through the open area and a small blue through the open area phasing out the 10 steam tons / hour and coal-fired boilers; 35 tons of steam launch built-up area / out of hours and coal-fired boilers. As of 2020, the city built basically out of the region 10 steam tons / hour and coal-fired boilers, coal-fired boilers within 10-35 tons of steam / hour range is substantially complete alternative clean energy sources, and no longer approve new 10-35 steam tons / hour of coal-fired boilers.

How many calories Horizontal one ton coal fired single drum threaded flue pipe steam boiler 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 coal fired single drum threaded flue pipe steam boiler 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.

Washing plant how supporting the right coal fired single drum threaded flue pipe steam boiler? In recent days we have several customers asked us to call consulting company has not washing equipment for steam boilers? What are the washing equipment manufacturers and supporting? In fact, we collaborated with the company several years ago a lot of manufacturers of Taizhou in Jiangsu, and Shanghai washing plant. General washing machine and electric heating steam boiler used in a hotel laundry, the electrically heated boiler cost is high, as electric steam boiler 1 ton per hour, power consumption of 760 degrees, coal-fired steam boiler into steam boiler, oil and gas steam boiler steam boiler, where coal-fired steam boiler in terms of equipment prices and fuel prices are the most provinces, with the national emphasis on environmental protection in many big cities of coal-fired boilers have been used to prevent, but we produced this coal is coal dual-use firewood, burning garbage can, and smoke from the chimney to the smoke is white, and the same plant where the flue gas desulfurization is the result of dust, greatly reduce the pollution of the environment. According to the number of gas-fired boilers for environmental protection, but gas-fired boilers to be determined according to local gas supply and prices, in some places there is no natural gas pipelines, liquefied gas, then if there is too cumbersome. Taikang County Hengyu Thermal Equipment Co., Ltd. has many years of production experience, has been relatively mature production experience and improve the quality system, at a cost of domestic and imported the most advanced production equipment to ensure that each boiler factory pass rate of 100 percent, the company sales team distributed in more than twenty provinces, lifting the user's worries. When washing room washing machine purchase should pay attention to the boiler
