March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.

It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.

September 3, 2018, Tangshan Municipal Government issued the "ecological environment in Tangshan depth remediation tackling month action plan", "plan" industrial enterprises in pollution control, discharge of pollutants in the cement industry to make the following requirements: single production of raw grinding material, bag filter employed; one mill kiln production process, humidification tower may be used - electric precipitator dust collection system, dust emission concentration ≤10mg / m³. Rotary kilns for cement kiln and, preferably high dust coating, conditioning tower may be used - electric precipitator, dust emission concentration ≤10mg / m3, the concentration of sulfur dioxide emissions ≤50mg / m3, nitrogen oxides emission concentration ≤ 50mg / m3.

3 ton biomass steam boiler in Sri Lanka Features

1.3 ton biomass steam boiler in Sri Lanka have advanced three pass wet back design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.

2.3 ton biomass steam boiler in Sri Lanka with advanced manufacturing equipment endows Safe and reliable property:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.

3.3 ton biomass steam boiler in Sri Lanka have large boiler proper heating area:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.

The characteristics of internal circulating fluidized bed boiler

The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:

1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.

2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;

3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;

4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;

5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;

6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.

7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.

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, szl biomass fired hot water boilers and water shortage in the traditional old-fashioned coal-fired boilers It is how to deal with? Electric 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.
