natural gas fired steam boiler for dairy
It is understood that, recently, the ecological environment Department of Henan Province issued the "Henan electricity in 2019 non-standard governance program industry" and six special programs, mainly to further promote the campaign of air pollution control, to ensure that the province's ambient air quality continues to improve. Meanwhile, the "plan" also made clear this year Henan Province industrial air pollution control in key tasks.
The province meet the conditions of steel, coke, cement, carbon (including graphite), flat glass (including electronic glass), aluminum and other six major industries and enterprises, the requirements before the end of this year to complete the mentioned standard treatment, the required limits for reducing pollutant emissions. Carry closed down or banned brick kiln, lime kiln, tunnel kiln, firing kiln and a variety of smelting furnace, roaster and so on nine categories of Kiln, upgrading, restructuring and integration work. Before the end of October this year, all kinds of industrial furnaces to achieve discharge standards.
Before the end of June this year, the province's petrochemical, oil refining, industrial coating, packaging, printing, chemicals, pharmaceuticals and other industrial enterprises, the full completion of volatile organic compounds pollution control; before the end of August, the province's petrochemical, oil refining companies to complete volatile organic compounds depth governance and leak detection and repair of governance; before the end of December, the provincial cities of built-up areas phasing out the open dry-cleaning machine.
Before the end of October this year, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province completed 35 steam tons / h coal-fired boilers and the removal or clean energy transformation, provincial cities and county (city) district built 4 tons of steam and above gas-fired boiler, fuel (including alcohol-based fuel) boiler low nitrogen transformation complete, the provincial municipality to build a biomass boiler area (including biomass power plants) completed the first ultra-low emissions transformation. Before the end of June this year, the completion of the provincial cities to build coal-fired facilities Chaigai all industrial areas.
Gas fired steam boiler for dairy loading, installation considerations gas steam boiler is a very wide range of special equipment, usually built in the boiler room. However, its load, the installation process, some issues must be taken, otherwise it may cause a certain degree of economic losses. 1, the process of handling and transporting gas in a steam boiler to be noted the following: the lifting capacity of the lifting device should be matched to the weight of the boiler Lifting. Can not be used for lifting has a length marked with a lifting lug can not be used should be chosen on the boiler rope, rope length to avoid inappropriate, leading to scratching furnace. In the loading, unloading and handling process must ensure that the boiler without any damage. 2, installation of boiler maintenance reserve space, make sure there is enough space for maintenance around the boiler. 3, the base gas steam boiler, the base of the boiler and precautions to be installed on the basis of 100-150mm above the floor of the boiler on the premises, subject to prior confirmation boiler manufacturing company with technical personnel, in accordance with the basis for construction drawings. Must stay out of anchor bolts embedded hole basis. Foundation must be able to withstand the weight of the boiler and the largest holding water amount. When the mounting base, must first be positioned. After the alignment adjustment in the end the length of two diagonal lines of the same base, then the entire tightening the fixing bolt. Base mounting reference line marked for reference. 4. General Precautions Be careful not to tilt too boilers and accessories and be impact. Can not be placed outside the boiler fuel. Do not dirty oil and water boilers should generally be installed in a separate boiler room, the new gas steam boiler room should not be connected to the house. A boiler can not be connected, (B) and (C) use of flammable liquid fire risk room. If the production plant is connected to the other, separated by a firewall application. 5, fire resistance rating of the boiler room of the building and fire safety requirements should be consistent with "architectural design code for fire protection" and "design of tall buildings for fire protection" requirements. Gas-fired steam boiler room on the ground should be smooth, non-flammable, no water, load-bearing foundation should meet the requirements. Gas-fired steam boiler supply voltage should be stable, to avoid burn electrical components. The voltage instability, is recommended to install regulators. To set the boiler room ventilation equipment, to maintain the boiler temperature at 50 ° or less.
As this consumer added, he wants to fire gas fuel and automatic operating system. Thus, our sales manager recommend him WNS type, single drum, horizontal structure, firing oil and gas. WNS 2000 kg fired steam boiler for dairy working together with autoclave can ensure the brick manufacturing process smoothly and successfully. Its horizontal structure and integrated design is very good-looking, and convenient to transport.
Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.
