Among Industrial Boilers, What Are The Differences And Characteristics Of Vertical And Horizontal Boilers? 2022-09-13 Vertical boilers and horizontal boilers are two types of industrial boilers, which are determined according to the internal structure design of the boiler. So, in industrial boilers, what are the differences and characteristics of vertical and horizontal boilers? Let Zhengzhou Fangkuai Boiler Factory answer for you.The characteristics of the vertical boiler: the combustion part adopts a double-layer grate combustor, which heats up and presses quickly, and after secondary combustion of the unburned gas, it has the functions of full combustion, smoke elimination, and dust removal. The elbow pipe arranged on the upper part of the furnace body is the convective heating zone, and the grate tube and the furnace bladder arranged on the lower part of the furnace body are the radiation heating zone. The structure of the furnace body and flue gas flow is reasonable in layout and has good heat transfer. The boiler has a reasonable design and a simple structure. Easy to operate and maintain, small footprint, low capital investment, is one of the ultra-small steam and heating equipment.Features of horizontal boilers: large water capacity, high thermal efficiency, fast steam production, sufficient steam, long service life, equipped with high-quality brand-name burners and pressurized feedwater pumps, sufficient combustion, timely water supply, and low noise; optional self-diagnosis function The computer controller can automatically shut down and give an audible and visual alarm when the operation is abnormal, indicating the fault code, which is convenient for maintenance; the protection device is complete, and the burner can be equipped with a high-temperature purge device, which is safe and reliable. Equipped with multiple protection devices such as high-quality safety valve, pressure regulator, low water level, and overheat protection to ensure the safe operation of the boiler; compact structure, small footprint, elegant shape, and bright color; small-scale tubular 30-300kg/h adopts vertical type Two-pass, 500-1000kg/h adopts vertical three-pass; high efficiency and energy saving: the furnace structure is optimized, and the heating area is large, especially the three-pass boiler has high thermal efficiency, fast gas production, and long service life. Optional high-quality brand-name burner and pressurized feed water pump, full combustion, no pollution, timely water supply, low noise, is the best equipment for industrial gas or heating above 5000 square meters.So, which vertical boiler or horizontal boiler has lower air consumption and lower investment cost? The technical engineers of Zhengzhou Fangkuai Boiler Factory also performed calculations and analyses for everyone. The gas consumption of the boiler is mainly determined by the efficiency of the boiler. In terms of cost, the choice of vertical boiler or horizontal boiler depends mainly on the installation site. Vertical boilers can be selected for small and small-scale applications, and horizontal boilers can be selected for spacious sites. In comparison, it mainly depends on the needs of customers, because the scope of use of these two boilers is different. For example, if you want to heat a 100,000 square meter community, then a vertical boiler is not acceptable. If you can’t bring a large heating boiler, you must choose a horizontal boiler. Industrial boiler.
What Are The Ways To Improve The Thermal Efficiency Of Industrial Boilers? 2022-09-13 Thermal efficiency data is very important for industrial boilers, which are directly related to the economic benefits of boiler users. It can be said that the design efficiency of the boiler determines the operating cost of the boiler. Generally speaking, the higher the thermal efficiency of the boiler, the greater the fuel consumption. Low, it will directly reduce the operating cost of the boiler.At present, as far as various furnace types such as oil-fired gas boilers and chain grate boilers are concerned, the average design thermal efficiency of domestic industrial boiler manufacturers is generally 70-90%, and the actual operating thermal efficiency is generally about 60-80%. Some small boiler manufacturers’ products are even below 50%. But in fact, there are ways to improve the thermal efficiency of industrial boilers. Let Zhengzhou Fangkuai Boiler Factory answer for you.Increase the effective use of heat, reduce boiler, exhaust heat loss, and mechanical incomplete combustion loss. Reduce the air leakage rate of the air preheater, especially the air leakage rate of the rotary air preheater. Strictly control the water quality index of the boiler water. When the scale content in the water wall tube reaches 400mg/m, it should be pickled in time. Try to burn fuel with a high calorific value to reduce the air temperature at the inlet of the air preheater. Modern large-capacity power generation boilers are equipped with air preheaters to prevent condensation on the heating surface of the cold front end of the air preheater, resulting in low temperature of the air preheater corrosion. Adjust the combustion conditions according to the boiler load and time, reasonably distribute the air, and reduce the center position of the furnace flame as much as possible, so that the fuel can be fully burned in the furnace. To reduce the heat loss of the boiler, it is mainly to strengthen the maintenance and repair of the boiler pipe and the insulation layer of the body.Scientific coal-burning ratio, rigorous process operation, improving air distribution, adding additives, etc.
What Issues Should Be Paid Attention To Ensure The Safe Operation Of The Boiler? 2022-09-13 Boilers belong to the category of special equipment. Ensuring the safe operation of boilers is a matter of primary consideration for companies using boilers. This is related to the personal safety of operators and the vital interests of the company. So, what issues should be paid attention to ensure the safe operation of the boiler?
