Boiler economizer is an energy-saving device installed at the tail of boiler flue. Its working principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in flue gas. As the economizer absorbs the heat of high temperature flue gas, it further reduces the exhaust temperature of flue gas, thus reducing the exhaust loss, improving the thermal efficiency of the boiler and effectively reducing the fuel consumption of the boiler. It is one of the important equipment of boiler system.
ZOZEN ZZ series medium-temperature and medium-pressure gas-fired steam boiler adopts "D" type 2 passes. It is double-drum natural circulation water tube boiler. The flue gas turns at the back of the furnace, enters the convection tube bundle of the second pass, then leaves the boiler body, and enters the economizer and condenser in sequence.
Industrial boiler is the main thermal power generation equipment in China's production and life, and its quality has an important influence on industrial development and residents' heating in winter. The fundamental factors that affect the quality of boiler are production and processing technology and tooling equipment. In the long-term production and operation, ZOZEN Boiler, as a well-known boiler brand, always pays attention to the renewal of process equipment, so as to continuously improve the quality and performance of various series of boiler products.
ZOZEN Boiler has designed a technical scheme for the project, including 3 sets of SZS series gas-fired superheated steam boilers and 1 set of WNS series gas-fired superheated steam boiler, of which two medium-temperature and medium-pressure SZS series gas-fired superheated steam boilers are used to cooperate with steam turbine for power generation.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
ZOZEN WNS series gas-fired and oil-fired boiler is equipped with the advanced condenser, which is a kind of flue gas waste heat exchanger whose working principle is the same as the economizer at the end of the coal-fired boiler. After a condenser is installed at the end of the boiler's flue gas duct, the high-temperature flue gas passes through the flue gas duct and the condenser at the same time, which can heat the water in the condenser, increase the feed water temperature and lower the exhaust gas temperature to achieve the goals of saving fuel and improving the thermal efficiency.
In recent days, it has been very hot in Jiangsu province and the temperature of some areas is as high as 39 celsius degree. In spite of the high temperature, workers in the workshops of ZOZEN Boiler are still busy as usual. They are not afraid of hot weather, stick to their positions and use sacrifice and sweat to interpret the meaning of diligence. High temperature can not consume their enthusiasm and hot weather can not stop their steps. Thank all the workers who make sacrifice for the development of ZOZEN Boiler! Today, we focus on these ZOZEN workers under the high temperature and show great respect for them!
