The body of oil fired steam boiler adopts corrugated furnace tube, threaded smoke pipe, three-return flue gas structure and unique large combustor design, which increases the heating surface and improves the boiler thermal efficiency. The oil fired boilers cost of recovery is fast, the front and rear smoke box adopts labyrinth seal structure, the switch is free and the smoke will not leak. The furnace body is provided with movable front and rear smoke box cover, which is convenient for detection and ash cleaning. The cylinder body is connected with insulating support, and the process of thermal insulation is adopted. The outer surface temperature is less than 50°C for normal operation. The burner interface adopts double interface, which is convenient for customers to switch between different fuels. The rear part is equipped with fire viewing hole to observe the combustion situation at any time.
This series of oil fired boiler body with explosion-proof door, safety and insurance measures to prevent future trouble. At the same time, intelligent automatic control system is adopted to provide multiple security protection during operation. It adopts the structure of wet-back and corrugated furnace, and the center of heating surface is arranged symmetrically, which makes the force and expansion of boiler more reasonable. Reasonable heating area ensures good water circulation and heat exchange, so that the heat transfer effect to the state, improve the boiler thermal efficiency. Adopt full butt weld wet back structure, avoid the back wall from high temperature smoke damage, ensure the boiler reliable operation. The combustion chamber adopts corrugated furnace, which effectively reduces the thermal stress of the boiler and improves the safety and service life of the boiler.
I plant oil-fired boiler in strict accordance with the drawings design and production. Oil fired boilers cost low of operation, boiler production with good drawing design, standard technical review, meticulous production inspection. In order to ensure that a product qualified solid foundation. The convective heating surface of the threaded smoke pipe can effectively improve the heat transfer efficiency of the boiler. Environmental protection effect is good. Part of CO2, NOX, SO2 and other harmful components in the flue gas are dissolved in condensed water, effectively reducing the discharge of atmospheric pollutants. Meanwhile, large-size furnace structure and flue gas recycling technology are adopted. For oil-fired boilers, ultra-low nitrogen emission and NOX emission ≤30mg/Nm3 can be completely realized, which fully meet the increasingly strict environmental protection requirements.
The key technical factors of industrial oil fired boiler include the relationship between condensation rate and exhaust temperature, the relationship between condensation rate and thermal efficiency, and the corrosion rate of condensed water to different types of steel. Through the reasonable design of heating surface, reduce the exhaust temperature, ensure the water vapor in the flue gas to meet the design requirements of condensation rate, so that the boiler thermal efficiency greatly improved. In the heat loss of WNS series boiler, in addition to the sensible heat of flue gas, steam also takes away a lot of latent heat of vaporization. If the steam in the flue gas is fully or partially condensed by lowering the exhaust temperature, and the latent heat released during the condensation process is recovered and utilized, the effective utilization heat of the boiler is increased, and the thermal efficiency of the boiler will be significantly improved.
Oil fired boilers cost is reasonable, the boiler adopts the structure of large furnace and corrugated furnace, which increases the radiation heat transfer area and facilitates fuel combustion. The fuzzy control technology based on artificial neural network and the world famous burner are applied to realize the automatic regulation of combustion according to the temperature, pressure and time, so that the boiler can run efficiently and economically under different conditions and reduce the consumption of fuel to the maximum extent. Zozen Boilers with low NOX combustion technology to optimize the structure of boiler design, through the automatic adjust the working condition of boiler combustion flue gas detection, thus ensuring the boiler flue gas emissions in line with the requirements of environmental protection, low operating noise.
