In hot water boiler, the selection of induced fan is to calculate the fuel quantity and air coefficient corresponding to the heat demand first. Then, the suitable induced draft fan is selected according to the total flow rate and the characteristic curve obtained.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type 1t diesel boiler machine ukraine paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
WNS horizontal oil fired steam 1t diesel boiler machine ukraine is adopted three-pass flame tube/smoke tube technology, which improve the efficiency significantly.ZG is a leading oil fired steam boiler manufacturer,WNS oil fired steam boiler stands for horizontal internal combustion with the rated evaporating capacity of 1-20 ton in China
The horizontal boiler, as a heat engine, has offered enough power for china’s industrial production. With the increasing application of the boiler, the problems raise. This passage will introduce the reasonable layout of the boiler’s chimney. After purchasing a boiler , the buyer need to install a chimney according to the boiler size and the site. The following are the relevant installation notions of the steel chimney and the brick chimney.
1.the steel chimney should be tough and hard enough. The chimney’s thickness should bear certain corrosion allowance. When the height of the chimney reaches 20~40cm,the diameter 0.2~1.0 m, the thickness of the body wall without liner should be 4~10mm, the body with liner should be 8~18mm.
2.The steel chimney’s lining can be born in subsection, the cracks between every two sections of 4~6m should be 20~50mm long. And the protection board should be installed on the top of the chimney. The chimney and the basic connection are made to conical support plate with the thickness of 20~40mm.
3.The steel chimney is better to choose the stainless steel one manufactured by the specialized factor. When the ratio of the chimney to the diameter exceed 20, a liable traction rope must be set, the rope should be 3~4 along the circle.
1.the height of the brick chimney should not more than 50m. The chimney should be equipped with maintenance ladder and lightening rod. Meanwhile, the bottom of the chimney should be set with a 0.5~1.0m dust hole.
2.If there are two connections between the chimney and the horizontal flue, the two connections should be set in the opposite direction and be separated with a board . The part higher than the horizontal flue should not less than its half.
