Uzbekistan: Smart Solutions Chemical Firm Navoiyazot Uses Industrial Boiler from Zozen
Zozen Boiler’s SZS series gas-fired steam boiler has been installed at Navoiyazot, a large chemical company in Uzbekistan, since the past one year for producing mineral fertilizers. The industrial boiler also helps to save energy and is highly efficient.
Moscow/Russia – Zozen Boiler had supplied a set of SZS series gas-fired steam boilers to AO Navoiyazot, a large chemical enterprise in Uzbekistan. The boiler has been running smoothly for about a year.
Navoiyazot is engaged in the processing of natural gas into mineral fertilizers and the production of chemicals. Constant temperature reaction, granulation, drying and other links in the high-pressure reaction kettle cannot be separated from the stable heat source provided by the industrial boiler.
Zozen’s SZS series gas-fired steam boiler adopts reasonable D-type arrangement of full-membrane wall structure, and all convection tube bundles in high-temperature area adopt anti-vibration fasteners, so that the fracture problem of convection tube bundles is solved, states the company.
The high-temperature resistant stainless steel CR25ni20 is adopted between the membrane walls, so that the flue gas short circuit is avoided to a certain extent.
In order to further improve the energy-saving effect, a condenser and economizer can be installed at the end of the boiler to fully recover the sensible heat of the flue gas and the latent heat of steam condensation, the thermal efficiency can reach over 98 %, adds the firm.
At the same time, good quality alumina silicate fiber and fire clay insulation is used, the boiler body temperature is controlled below 45℃, to reduce heat loss. The above methods ensure the energy-saving and high efficiency of the boiler.
