ZOZEN WNS series gas-fired hot water boiler is designed with the internal combustion structure. The boiler can choose several kinds of fuels, such as the natural gas, biogas, coke oven gas etc. The fuel is burning sufficiently in the furnace and transfers heat through the threaded smoke tube to improve the thermal efficiency. Welcome to learn more details on the hot water boiler via online chat service.
ZOZEN Boiler provided an energy-saving and environment-friendly WNS gas-fired steam boiler for a food enterprise in Suzhou. The gas-fired steam boiler adopts two-pass design, and the use of large-diameter corrugated furnace and threaded smoke tube make the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach more than 98%.
Boiler economizer is an important energy saving device in boiler system. Its principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in the smoke. Economizer can be divided into cast iron economizer and steel tube economizer according to different manufacturing materials. This gallery displays the cast iron economizer produced by ZOZEN Boiler. The cast iron economizer is mostly used in boilers with pressure ≤2.5 MPa. If the pressure exceeds 2.5 MPa, the steel tube economizer should be adopted.
According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. ZOZEN SZS series double drum vertical gas-fired watertube boiler is a typical medium and large-sized gas-fired boiler, with a capacity of 20-110t/h and a pressure of 1.25-5.3MPa, which meets the needs of steam and heating for most enterprises. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the photos show the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
ZOZEN Boiler as a leader enterprise in the gas-fired boiler industry always pays attention to the energy-saving and environment protective technology and has received remarkable achievements. In order to make full use of the waste heat and to meet the different requirements of different working conditions, ZOZEN engineers have innovatively designed various types of the energy-saving gas-fired boiler system solutions, such as the condensing type, air preheating type, waste heat boiler type, etc. Through the energy efficiency test, the thermal efficiency of ZOZEN energy-saving gas-fired boiler is over 98%, which is better than the national energy efficiency standard.
Before delivery, ZOZEN gas-fired fire tube boiler shell is covered with the stainless steel film to prevent damage to the boiler shell in the process of transportation and installation. The film will be removed after installation. The mirror stainless steel shell of the boiler has the features of low heat loss and beautiful appearance. The pictures show the blank pressing process of the stainless steel materials, which is the previous process of installing the stainless steel film, this process aims to make the material seam much flatter and firmer where surfaces intersect and meet.
ZOZEN YLW series coal-fired and biomass-fired chain grate thermal oil heater is favored by Indonesian customers because it has the features of high temperature and low pressure, precise temperature control and high quality. Heater proper and chain grate are transferred separately. The pictures show the heater proper is on the delivery. YLW series thermal oil heater adopts the square coil structure to realize high safety and sufficient heating surface. The tubes are firstly bent by CNC 3D tube bending machine, then welded to link together without forced assembly. YLW series thermal oil heater adopts the structure of a large furnace to achieve sufficient combustion and realize the thermal efficiency of over 85%. It is available for the bituminous coal, anthracite, all kinds of biomass particles, sawdust, etc.
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.
