1 ton fire tube industrial gas wns steam boiler price
When the pressure of the 1 ton fire tube industrial wns steam boiler price protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.
Process describes extinguishing gas 1 ton fire tube industrial wns steam boiler price the fuel gas steam boiler characteristics of fossil fuels, biomass fuels extinguishing mechanism in the extinguishing process, the composition of the reaction products and quenching rate is also very different from the fossil fuels. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Extinction characteristic different from the fossil fuels of fossil fuels. Extinguishing process gas steam boiler biomass fuel is divided into two separate phases: volatile precipitation and extinguished, and a gas steam boiler and burn off the coke. The former account for about 10% of the time of the fire, which is about 90%. Specific extinguishing process as follows: After gas steam boiler fuel to the quenching chamber, heating the water and precipitated at high temperature thermal effect. Subsequently, the fuel gas steam boiler because the temperature continues to rise, from about 250 degrees Celsius, thermal synthesis starts, volatile precipitate and form coke. The volatiles were mixed and the temperature of air around the first gas steam boiler is ignited and extinguished. Under normal circumstances, the surrounding coke is volatilized gas steam boiler sub-extinguishing chamber oxygen is difficult to penetrate into the surface of the coke, as long as volatiles to dissipate the end, the temperature in and around the coke gas steam boiler has been very high, oxygen in the air may also be in contact with the exterior of the coke, coke gas steam boiler start off, it does produce ash when.
Recently, Yuhang District, Hangzhou, Zhejiang Province, a printing company 20 steam tons / hour of coal-fired boilers have been stalled, this is the last Yuhang district an industrial coal-fired boilers, which marks the shutting down of Yuhang District of industrial enterprises to bid farewell to coal energy structure of coal turned to natural gas and other clean energy, Yuhang District from entering the industrial coal-free era.
Yuhang District "coal-free zone" construction of road resistance and long. As a major industrial zone, a long time, Yuhang District to focus on coal-fired thermal power plants, coal-fired boilers and other industrial enterprises formed a coal-dominated energy consumption structure. In 2014, the maximum amount of coal Yuhang District reached 783,600 tons. Large coal consumption that emissions of sulfur dioxide, dust and the like remain high for many years.
In order to further deepen the air pollution control, to win the Battle of the blue sky, Yuhang District, from 2017, will gradually tangqi thermoelectric, thermoelectric and sea Chongxian three coal-fired thermoelectric power plant with all closed down, the sea of clean natural gas for thermoelectric realized heat. 3 thermal power plant shut down so that the region's coal consumption, pollutant emissions and other indicators to achieve substantial reductions in road construction of "coal-free zone" has taken a crucial step.
Yuhang bid farewell to coal road this did not stop. While coal-fired thermoelectric accounted for the bulk of coal consumption and pollution emissions, but only out of coal-fired power plant is not enough. 2018, the government decided to promote taking advantage of Yuhang District, the region within the remaining four coal-fired industrial enterprises (Coal Products) pot (kiln) furnace closed down or eliminated or modified.
Yuhang District to increase the proportion of electricity consumption, and actively guide the region's energy unit of coal to electricity, oil to electricity, gas bottle to electricity, the construction of an orderly distribution grid, promoting smart grid construction; continue to improve the level of utilization of natural gas, and urban area in addition to all the town cormorant birds, Baizhang full realization of natural gas supply, a total of 850 kilometers of natural gas pipeline construction and municipal gas transformation 45000; to promote the application of photovoltaic power generation, the region's industrial and commercial enterprises amounted to 173 megawatts of photovoltaic capacity building distributed, clean energy applications has taken shape in Yuhang District.
According to statistics, "Thirteen Five Year Plan" (2016-2020) since the implementation of environmental statistics included in Yuhang district industrial enterprises coal consumption from 588,900 tons in 2016 down to 38,900 tons in 2018, to drop in early 2019 0.
A substantial decline in coal consumption is brought to slash emissions of pollutants and air quality improved significantly. 2018, the main pollutant urban air Linping PM2.5 average concentration of 38 micrograms / cubic meter, decreased 40% in 2015. Region sulfur dioxide emissions of 7,833 tons in 2014 to 2018 had dropped more than 90%; NOx emissions to 8490 tons in 2014 to 2018 had dropped more than 60%.
Principles of 1 ton fire tube industrial wns steam boiler prices 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.
