Coal to natural gas operations bunch of factors that vertical pressure steam industrial boiler in oceania energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.
6 tons adjusting a combustion gas steam industrial boiler in oceania, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
Why condensing industrial boiler in oceania sales will increase every year? Under the influence of the modern concept of energy saving in the purchase of products like heating is more popular in condensing boilers, statistics confirmed that showed sales rising year by year in the state during the years of research and development come out of condensing boilers. So why year after year of rising sales of a full range of condensing boilers do? We will be analyzing the reasons for the rise in sales of condensing boilers below. One reason, can save heating costs are well known in the modern condensing boiler has not yet come before people in many parts of the device only by means of conventional boiler when heating is influenced by the principle of cause conventional boilers spend a lot of energy to release some heat . But they have very different condensing boilers and conventional boilers in the design and working principle of the above, the use of modern release can save heating costs on top of a relatively large amount of heat condensing boiler to a certain extent. Two reasons, can reduce the frequency of replacement of modern heating equipment currently on the market of raw materials existing ordinary boiler product is mostly copper, after long-term use of corrosion and thus vulnerable to a series of failures to be replaced. Condensing boilers produced material was stainless steel, even if the contact during operation of the steam does not affect their quality will be able to make virtually modern replacement frequency heating apparatus is controlled. Class three reasons, the release of a very small amount of nitrogen oxides during the operation most of the conventional type boiler in operation of heating equipment are required to coal-derived material as a raw material, coal or the like at the time of combustion of the material will release a large ships harm air quality material composition. While condensing boiler during operation of the steam is produced after combustion of natural gas as a raw material, and therefore the operation at the time of release of the content of nitrogen oxides is much lower than a predetermined standard. Analysis of the reasons condensing boiler sales rising year by year made temporarily come to an end. Through the above three reasons we can have some understanding of the advantages of using credible condensing boiler from the side, I believe that with these advantages condensing boiler different from the ordinary boiler heating equipment will continue to grow in future sales.
April 17, Nantong, Jiangsu Province, the municipal government issued the "Nantong City 2019 air pollution control program of work" ( "Program"). "Plan" is mentioned: Nantong City, 153 Taiwan industrial boiler in oceania regulation reform, which involves natural gas boilers, biomass boilers, coal-fired boilers; renovation project and will continue to implement ultra-low emission coal-fired units, a total of six thermal power companies more than 10 sets of 75 tons of steam / hour implementation of ultra-low emission coal-fired boilers.
