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.
The shipment of ZOZEN SZL series chain grate boiler for R.R.P AGRO FARM.SZL series of biomass-fired boiler is one of ZOZEN’s patented products. It has the characteristics of wide fuel adaptability, less occupied area, convenient installation and high thermal efficiency. ZOZEN biomass-fired boiler is suitable for a variety of fuels such as biomass pellets, wood blocks, palm shell, rice husks, corncobs and wood waste. In order to improve the overall efficiency of the boilers, ZOZEN rationally designs different feeding systems according to the characteristics of different biomass fuels. By extending the furnace arch, increasing the height of the furnace, adjusting the width and length of grates, etc., ZOZEN has taken the lead in solving the problems commonly occurred in conventional biomass-fired boilers, such as furnace arch burning down, furnace door burnout, backfire in hopper tempering and tube shell coking.
Recently, ZOZEN delivered the thermal oil heaters for Hengfa Energy Saving Technology. As a leading industrial boiler manufacturer, the thermal oil heaters of ZOZEN have wide adaptability of fuels, are suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. The heaters are also equipped with the advanced burners to ensure the NOx emission is below 30mg/m3.
Vietnam has abundant coal resources, including anthracite, bituminous coal, lignite, and peat. Vietnam anthracite has the characteristics of high calorific value, low ash, low nitrogen, low phosphorus and low sulfur. ZOZEN SZL series coal-fired boiler has wide fuel adaptability and sufficient fuel combustion, and has established an excellent reputation in the Vietnamese market.
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
