boiler ash melting chemistry oil

oil and gas boiler ash melting chemistry price

Oil and gas boilers have a high share in the international market. This is related to many factors, such as the high environmental performance of the boiler, full automation, and fuel factors. The oil and gas boiler price has become one of the factors of concern for customers.

In June 2015, a textile plant in Odessa, Ukraine visited our factory. Before this, we have contacted with each other about 10 ton steam boiler ash melting chemistry. Our senior sales manager Summer introduced our WNS natural gas boilers and achievements, history about our ZG Boiler. ZG Boiler has got international certifications such as GOST, ASME, IBR, etc. Each year, there will be sets of industrial boilers exported to Russia, India, Pakistan, America, Japan, England, etc. We have rich experience in industrial boilers manufacturing such as natural gas fired boiler, oil fired boiler, biomass fired boiler, coal fired boiler, cfb boiler, waste heat recovery boiler, etc. Our advanced engineers team can give you pesonal tailor on your industrial requirements. Saving money and energy is our pursue in boiler designs. Our industrial gas fired steam boiler has long life service and good quality. Its horizontal structure in design makes it convenient to transport and install. And our natural gas fired steam boiler with automatic operation system, is safe and benefit to the boiler operator.

Access the PolockGroup Group, the overall strength of the other side of the fast group, boiler ash melting chemistry quality and after-sales service system are full of praise, and the company signed a three star product - one condensing steam boiler (WNS5-1.25-Y.Q). Up to 104% thermal efficiency of the boiler, the exhaust gas temperature as low as 70 deg.] C and a stable, continuous output of high-quality steam, is valued PolockGroup group. This cooperation is not only a strategic cooperation between the two companies, but also the party pushed forward on the pattern of fast boiler in overseas development, to further promote the party soon Group to expand overseas market a new road.

Gas condensing boiler ash melting chemistry Gas condensing boiler Products That condensing gas boiler, the key lies in condensing technology, is a new, energy-saving and environmental protection boiler. By condensing gas boiler flue gas condensing boiler means the exhaust gas temperature can be reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and steam, the highest thermal efficiency of the boiler up to 102%. Gas condensing boiler uses condensing gas boiler products can be widely used in hotels, schools, hospitals, textile mills, cafeterias, restaurants, food plants, pharmaceutical plants, packaging plants, building materials factory, swimming pool and other enterprises place. Advantages of gas condensing boiler 1, one-piece design condensing boiler boiler efficiency compared to more ordinary, more environmentally friendly. 2, a condenser and an economizer disposed tail, achieved using a flue gas waste heat step, fully absorbed the heat in the flue gas; high heat transfer coefficient of the threaded pipe, the effect of convective heat strengthening, boiler efficiency up to 102% . 3, classic three return, all wet back structure: low resistance, high efficiency. 4, all-furnace corrugated furnace structure, strengthen the disturbance smoke while increasing the radiative heat transfer area; increase rigidity furnace, effective to attenuate the expansion stress of the furnace, and long service life; enhanced heat transfer, the combustion of fuel more fully. 5, a large volume of the combustion chamber design, fuel adaptability, and can be fully adapted to a variety of city fuel gas, natural gas, light diesel oil and heavy oil. 6, positive pressure combustion, fuel combustion, less smoke emissions, are in line with national emission standards. 7, using the first all-welded and then pre-expanding, then Expansion of advanced technology, high quality welding, testing 100% pass rate. 8, Germany Germany Weishaupt burner, Olin Finland, Italy Riyadh Road, Germany Paterson and other well-known international brands burner. 9, condensing unit, outstanding economic performance, the lowest in the province 60,000 yuan. Product Structure gas condensing boiler using condensing gas boiler wet back three return, full corrugated furnace, threaded pipe structure, large volume of the combustion chamber is provided, the combustion more fully; tail saving additional condensing means, which can effectively absorb heat generated by the fuel, improve the thermal efficiency of the boiler, reducing input costs and reduce pollutant emissions. Advantages condensing gas boiler 1, a high thermal efficiency: economizer, the boiler and condenser integrated structure, sufficiently absorb heat and smoke emission latent heat of vaporization, high thermal efficiency more than 10% than the average furnace; 2, the exhaust gas temperature is low: energy , a condenser, a three-dimensional design, efficient heat transfer, corrosion-resistant materials, the exhaust gas temperature up to 60-90 ℃; 3, energy saving, environmental protection: flue rotary combustion technology, full fuel combustion furnace with ordinary than about 10% fuel savings, harmful gas emissions to the national standards; 4, high quality silicate insulation material and double sealing structure, thermal insulation, good sealing performance.
