To implement the central authorities on the construction of ecological civilization and major decisions and plans, "the Jiangsu provincial government office on efforts to reduce coal year 2019 work" (Su Zheng Ban Fa ﹝ 2019 ﹞ 45) requirements, carry out the "263" special action, continued reduction of non-electric industry (including captive power plant) coal consumption, in the middle of this month, Nanjing people's government Office issued the "Nanjing 2019 work program minus coal." Compared with the 2016 base, the city of Nanjing in 2019 non-industrial enterprises in the coal power industry regulations reduction target is 3.88 million tons, 13.3 million tons less than total control.
"Plan" clearly requires, Nanjing will further reduce the implementation of industrial coal, increase the elimination of backward production capacity and inefficient excess capacity Yajian efforts to accelerate the implementation of the chemical industry regulation to enhance and accelerate the implementation of Nangang, Meishan Steel coke production capacity out of work year after year, to speed up eliminate backward production capacity of coal, cement clinker production capacity in an orderly exit.
At the same time, to promote structural reduction of coal, the implementation of ecological and environmental protection requirements of the Yangtze River economic belt along the Yangtze River to promote the orderly relocation of key enterprises and industrial transformation and upgrading, the city's coal consumption structure and strive to achieve a fundamental change; accelerate the aging coal-fired non-compliance unit outage work.
According to the requirements, "plan" put forward, Nanjing will also strengthen reduce coal progress warning. Less coal combined monthly schedules, reducing the monthly publication Coal risk warning, the cumulative assessment carried out in accordance with the red, yellow and green three levels. Less progress of coal coal consumption does not exceed a custom schedule for the green light; cumulative coal consumption over a predetermined schedule within 2% of the yellow light, will be issued urge communicated, to be a reminder and a warning; the cumulative coal consumption over a predetermined plan of 2% or more for the red light, will be relevant area (park) conduct interviews, and urge them to implement technical, administrative and other measures to encourage companies to reduce coal consumption over consumption.
Biomass fuel has the following main characteristics compared to coal:
1. Low sulfur content. Biomass fuels are mostly less than 0.2% sulphur, and there is no need to install a gas desulfurization device when burning, which reduces costs and is environmentally friendly.
2. Most of the carbon in the biomass fuel combines with hydrogen to form a low-molecular hydrocarbon. After a certain temperature, it thermally decomposes and folds out the volatiles. Therefore, biomass fuel is easily ignited,
3. The density is small. The density of biomass fuel is obviously lower than that of coal, and the texture is relatively loose, especially crop straw, which is bulky.
4. Less carbon. The highest carbon content in biomass fuels is only about 50%, which is equivalent to the carbon content of lignite with less generation.
5. Straw biomass contains a large amount of alkali metal elements (mainly potassium and sodium). In the combustion process of biomass, the main performance is that the adhesion of ash is strong, and slagging and clogging are likely to occur in the furnace. Ash accumulates on the heated surface of the tail.
When the gas steam blown waste heat boiler startup procedure installation is complete, you should first check whether the internal boiler tidy and clean without foreign body, and then close the manholes and valves. Oil (gas) pipeline, and the return line of compressed air to blow the pig debris, and then connect the burner fuel supply port, check the connection is tight, then a predetermined pressure test.
The beverage plant needs steam in its beverage degassing ,sterilization, and packaging process. 3 ton steam requirement per hour came from beverage plant steam requirements in all process. Then, why there must be WNS series, any other choice here? WNS series steam capacity is from 2 ton to 10 ton, more suitable for lower capacity steam blown waste heat boiler startup procedure. Of course, we also have SZS series which capacity is from 4 ton to 30 ton. To larger steam requirements, industrial gas oil fired power plant boiler is also available. If you want to use other gas fuels like lpg gas, bio-gas or liquid fuels like diesel oil, heavy oil, light oil, our WNS series steam boiler also can burn them. But, like our advanced engineer said before, each boiler is specialized for one designated fuel, this WNS series 3 ton steam boiler is manufactured to burn natural gas. Although it can burn other fuels, it can reach highest thermal efficiency when burning designated fuel natural gas.

The carbon is removed from the gas with water, extracted in most cases with feed oil from the water, and returned to the feed oil. The high reformed gas temperature is utilized in a waste heat boiler for generating steam. The steam is generated at 850 to 1565 psi. Some of this steam is used as process steam and for oxygen and oil preheating.Get a Quote

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.Get a Quote
