natural gas boiler for steam distillation
How to solve the air pollution problem caused by food processing boiler for steam distillation operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
Principles of steam boiler for steam distillations and solutions hydraulic external gear of Henan fast boiler's small series with you about the principles of steam boilers and solutions Steam Boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil three kinds of steam boilers, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, large steam boiler return of more than three horizontal structure . If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories. From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blowing into the combustion chamber is a lower place, such steam boilers greater resistance, require forced air. Steam boiler cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. Steam boiler flue gas from the back of the boiler, the steam drum of a boiler return line before the smoke tube, returned by two return rear smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. These are the works of steam boilers, steam boilers run course, ultimately, other devices, such as induced draft fan not only bear the task of exhaust fumes, or negative pressure necessary for operation of the steam boiler. As well as pressure vessels, thermometer, safety valves, pressure gauges, pumps, steam pumps, and so on. They are essential for steam boiler work. Pump leaks. Gear pumps for leaks during operation, leading to its actual output is smaller than the theoretical flow of traffic. The main channel is leaking gear pump: through the gap between both surfaces and both side surfaces of the gear cover side leakage, accounting for 75% to 85% of the total leakage of the pump; radial gear tip circle between the inner hole and the pump CLEARANCE ; gap by engagement of the gear leak. The gear pump due to the presence of a leak, so that the output pressure do not increase, the influence of the use of a gear pump. In order to solve the low gear pump output pressure problems, may be employed on both sides of the elastic gear plus floating collar or baffle manner, to reduce the leakage of the gear pump, the gear pump to increase the output pressure. Radial force imbalance. In the gear pump during operation, the pressure acting on the outer gears are not equal, resulting in the gear and bearing at the axle radial imbalance force. This unbalanced force will accelerate the radial bearing wear and reduce the service life of the bearings, the gear shaft deformation can also cause friction with the inner hole of the addendum pump, pump damage, so that the pump does not work. The solution generally adopted is: ④ opening pressure balancing grooves to the pump, the high pressure oil introduced into the low pressure zone, but will increase the pump leak, the influence of the volumetric efficiency of the pump; ② size reduction oil pressure chamber, acting on the teeth the pressure area is reduced, thereby reducing the radial force imbalance.
Environmentally friendly electric boiler for steam distillation steam mill price for how much this government now demands that environmental protection is more and more strict. Many places began to phase out coal-fired boilers are, so these are beginning to use environmentally friendly electric or gas boiler steam boiler. For paper mills, most of the mills are using the gas, but still there are a lot of plants using steam power, so there is recent paper mill specific price consulting to fast boiler electric steam boiler. 1T current price of electric steam price of around 90,000, the paper mills use electric steam boiler 4t is to meet the production needs, the purchase of the paper mill electric steam boiler environmental cost of around 36 million.
Currently, Yancheng City, Jiangsu Province, has issued the latest "Battle of Yancheng win the blue sky plan", in full swing atmospheric environmental governance. Details are as follows.
First, to promote non-power industry emissions of nitrogen oxides depth and steel industry to implement ultra-low emissions transformation. Achieve before the end of June 2020 discharge standards garbage incineration industry, gas-fired units are encouraged to implement advanced nitrogen removal, implementation of coal-fired units plume of white vapor recovery off the project.
Second, the implementation of total coal consumption control. Accelerate the "Yancheng reduce total coal consumption special action plan", strictly implement the same amount of coal consumption reduction alternative requirements, increase bulk coal remediation efforts for non-electric Yajian coal industry, and gradually increase the proportion of coal. New coal coal project implementation reduction instead. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, the power sector coal consumption accounts for the proportion of total coal consumption to increase more than 65%. Continue to promote alternative energy coal and oil, electricity consumption by 2020 (calculated as the supply of standard coal) accounted for about 55% of the total social energy consumption.
The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity, the new electricity in the area rely mainly on non-fossil energy generation and transmission to meet outside.
Third, carry out comprehensive improvement of coal-fired boilers. Before the end of 2019, 35 tons of steam / hr and coal-fired boilers or eliminated all clean energy alternative embodiment, suitable remediation in accordance with the principle of the electric power, gas and other appropriate gas is to encourage the use of solar energy, and biomass energy; promote clean coal use, promoting clean and efficient coal-fired boiler, steam 65 t / h coal-fired boilers and more energy-efficient and ultra-low emissions completed transformation; low-nitrogen gas boiler is substantially complete transformation; urban area biomass boilers embodiment ultra low emission transformation; rest boilers with all the special emission limit requirements.
