Fang soon have years of experience in research and design for condensing high pressurefield steam injection boilers to produce condensation products boiler thermal efficiency up to 107%, nitrogen oxide emissions can be less than 30 mg / cubic meter, and also set safe and convenient, long life, furnace cooler-running small number of advantages such as loss, after once the market widely loved by users and usage.
Yangzhou City in Jiangsu Province, the municipal government issued a notice of 2019 annual remediation tasks high pressurefield steam injection boilers, with the text published a list of boiler regulation, as follows.
3, the nitrogen gas boiler oxide (NOx) emission limit is not higher than 50 mg / m transformation, in accordance with other indicators of "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
(1) prohibits blended with other fuels such as coal, bags and other supporting efficient dust removal facilities, and effectively discharge standards. Emission standards in accordance with "boiler air emission standards" in coal-fired boilers particularly performed emission limits.
Full implementation of the above steam 2,65 t / h coal-fired boiler transformation ultra-low emission, soot, sulfur dioxide, nitrogen oxides, respectively, 10 mg / m, 35 mg / m, 50 mg / cubic meter.
3, disable all kinds of close small coal-fired facilities (tea boiler and furnace operating coal-fired stove, rural production, aquaculture and other coal-fired facilities), switching to natural gas, electricity, solar and other clean energy. In remote rural areas, could be replaced by forming biomass as a fuel, but must use a professional boiler, supporting efficient dust removal facilities, to ensure that pollutant discharge standards, emissions standards refer to "boiler air pollutant emission standards" in particular coal-fired boiler emission limits carried out.
4, a low nitrogen gas boiler and treatment for the transformation, the installation of low NOx combustion by the low NOx combustion mode, etc., to ensure that the nitrogen oxide emission limit is not higher than 50 mg / m. Other indicators according to "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
5, forming a comprehensive remediation biomass fuel boilers, biomass fired boiler clean-up does not meet the special requirements of the boiler, not supporting a biomass fired boiler emissions and efficient dust removal facilities of non-compliance. To meet the special requirements of the boiler and supporting efficient dust removal facilities, the establishment of accounting and retain more than one year, emission standards refer to "boiler air pollutant emission standards" emission limits in particular the implementation of coal-fired boilers. More than 10 tons of steam installation of gas-line monitoring instruments, and networking with the environmental protection department. Located in the city built-up area forming ultra-low emission biomass boilers implement reform.
6, bulk coal sales within the city limits are all clear according to the law, the use of bulk coal user implementation of the "coal to electricity" for street vendors and other "coal to gas" campaign, a pin number management. At the same time, prohibiting the establishment of long-term supervision mechanism bulk coal, non-bulk coal inflows.
Horizontal steam high pressurefield steam injection boilers how to discharge of sewage (1) of the sewage inside the valve opened; (2) the discharge of sewage slowly opened outwardly of the valve, and discharges the sewage preheating duct; (3) back and forth toward the switch sewage outside the valve, the pot slowly flushing dirt stains, so stains best dirt discharge; (4) closing the valve inside the sewage, the valve between these two stored sewage water discharging; (5) Close the valve outwardly sewage, sewage discharge is completed.
Hot water high pressurefield steam injection boilers combustion chamber to prevent the return tube plate cracking measures what? Tubesheet before returning to the boiler combustion chamber is working three worst backhaul site, a long period of high and low temperature thermal stress, likely to cause thermal fatigue cracking tube end, where this configuration is the most prone to boiler problems.
high pressure steam comes out the other. The Clayton Steam Generator is a unique design that does just that. Instead of the familiar steam train image of a boiler we now have a compact steam making machine with staggering advantages for the world we live in today. The Clayton Steam Generator uses only three main components.Learn More
Oil field steam boiler is also called moisture steam generator or steam injected boiler, which is special equipment for thickness oil field exploitation. Boiler produce High temperature and high pressure steam to heat the raw oil under earth to reduce viscosity of thickness oil and increase the liquidity of thickness oil.Learn More
High-Pressure Boiler Definition. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.Learn More
Steam injection is the most widely used EOR method today. In 2008 global EOR oil production climbed to 2 million barrels per day of which 1.2 million was attributable to steam injection. This process is therefore the most advanced EOR method as far as field experience is concerned.Learn More
Shengji High Pressure Horizontal Steam Boiler. high pressure steam injection boiler. A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure . Get a Quote. Learn MoreLearn More

Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum.Learn More
Earlier field tests of SAGD in Athabasca tar sands were successful at a depth of about 600 ft, which is too deep for surface mining and not deep enough for high-pressure steam injection. SAGD is a complex process because gravity flow strongly relies on a high vertical permeability.Learn More
