wns fire tube gas fired boiler

After party fast track late after-sales staff feedback display, stable operation of two wns fire tube fired boilers at Mi Duoqi food and dairy cattle Flower boiler room in the two companies, to provide heat support for food processing. It is fast boiler of the brand stick, adhere to the quality of products as well as high demand for post-maintenance feedback, so that the two food industry enterprises in Henan Province invariably choose and we walk hand in hand!

The characteristics and stove works Here are just some of the basic information about our company stove. First, my company to develop and produce high-temperature hot stove can provide clean, sustainable source temperature, it has been widely used not only dried food, food, medicine, tobacco, animal husbandry, agricultural and sideline products and various kinds of industrial materials, printing, drying the paint and other heat sources, it can be used for tall plants, such as plastic greenhouse heating, and underground mines, underground engineering, where heating to be dried and lower humidity. Second, Yinxing Company and ship wns fire tube fired boilers 713 Institute jointly developed the high school low-temperature hot stove technology heritage, good heating effect, won praise users. Third, the high temperature gas can be directly incorporated into the drying room intake pipe, since the stove burner can be achieved, automatic temperature control, so the stove will start automatically according to the temperature sensor, stopping, adjusting the combustion state, to achieve the intended purpose. The working principle of the heat exchanger and the combustion chamber stove into one, all-steel sleeve multilayer structure, which is the lower part of the reactor core combustor, and surrounded by an upper annular heat exchangers, air and flue gas are bis backhaul , prevails, for heat exchange. In order to improve the thermal efficiency using the principles of heat transfer technology and the long helical groove turbulence sheets, Save thin sub-layer, the air and flue gas are constantly changing during rotation, greatly enhanced heat transfer. The main process is: burning coal in the furnace to produce high temperature flue gas, enters a loop under the action of the fan, exchanging heat with the outside air, is discharged via the chimney flue; stove cool air blown by the blower housing, the outside air into the cavity top wall ring, a clean hot air from the duct supplying hot air device for an outlet.

Because of the particularity of the oil-gas wns fire tube fired boiler, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.

Burner fuel gas selected selection principles which fuel gas wns fire tube fired boiler burners should be based on structural features and performance requirements of the boiler body, in conjunction with user conditions, making correct comparison, several general principles according to the following options: 1) according to user selection of used fuel type, liquid fuel kerosene, diesel oil, heavy oil, residual oil and waste oil, fuel gas city gas, natural gas, liquefied petroleum gas and biogas, fuel should have the necessary analysis of data used: ① kerosene, diesel should have heat and density. ② heavy oil, residual oil and the viscosity should, heat, moisture, flash point, mechanical impurities, ash, freezing point, density and the oil temperature. ③ should calorific gas, gas pressure and density. 2) to select the type burner nozzle atomization method or the gas burner and the furnace structure according to the performance of the boiler. 3) the burner output should match the rated output of the boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion. The rated output of the boiler and boiler efficiency is determined, the fuel consumption is calculated, and then selected according to power a single burner arranged to determine the number of burners. Increase the number of burners, in favor of the atomization quality assurance wind oil mix, but too many, and not easy to operation and maintenance, will give burner arrangement difficult. 4) adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. 5) fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. 6) Effects of noise and smoke emission must comply with environmental standards, mainly emissions S02, CO and NOx must be lower than the predetermined country, should use low NOx burners and low noise. There are integral and split two 7) a burner assembly embodiment. I.e. monolithic burner body, the burner and a combustion air blower system (including an oil pump, a solenoid valve, a servo motor or the like) into one; split i.e. burner body (comprising a combustion head, oil or gas systems), fans and combustion burner control system (including the control box, fan thermal relay, AC contactor, etc.) are each independent three-part system, according to the specific requirements of the boiler and user choice. Simple 8) should be used in construction, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. 9) to deal with the burner brand, performance, price, and service life of comprehensive comparison. 10) In addition to the burner air pressure to overcome the resistance of the boiler body considered, but also to overcome the resistance and flue gas economizer system.
