ZOZEN WNS series gas-fired hot water boiler adopts packaged structure, which is convenient and quick for installation to save a lot of basic construction costs for the enterprise. Its internal structure adopts large-diameter waveform strove furnace which can effectively absorb heat expansion to add the radiation heating surface and ensue the low emission of NOx with the advanced low-nitrogen burner to improve the fuel utilization. What's more, its thread smoke tubes have scientific pitch and depth to further strengthen the convective heat transfer and make boiler's thermal efficiency reach 95% and above.
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.
This kind of heater adopts three pass circular tube design for sufficient heating surface, and the waste heat boiler and energy-saving device disposed at the tail of the heater can greatly reduce the loss of thermal energy, the thermal efficiency can be as high as 95% or more. Advanced low NOx burner can achieve NOx emissions below 30mg/Nm³. And the operation of the thermal oil heater can realize full automatic control, and can automatically adjust the combustion, high tank level, outlet temperature and flow to ensure the safe operation. This series of thermal oil heaters are favored by all walks of life in the chemical, rubber and food industries.
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.
In the petroleum industry, steam is the main factor affecting the energy consumption of enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. ZOZEN provided the company with SHL series field assembled water tube steam boiler. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler.
ZOZEN YY(Q)L series vertical thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN SZL series coal-fired (biomass-fired) boilers have wide fuel adaptability, applicable to a wide range of fuels including all kinds of coals and biomass particles; they have the charactics of sufficient output, safety, high effciency and high degree of automation. Meanwhile, this series of boilers is equipped with an advanced control system, which is safe and worry-free.
The ZOZEN coal-fired hot water boiler helped the heating company to successfully complete the centralized heating task in winter with its excellent performance, reliable operation and friendly environment performance. The tailor-made boiler system of ZOZEN realized the high efficiency and energy saving of the heating system, and provideD sufficient heat source protection to ensure the warmth of the people in the area.
