Product Details

Shandong Huayuan Boiler Co., LtdProduct Features
The boiler body is designed with double drum, single-layer layout, compact structure, and large heating surface. The heating surface of the boiler is 10% more than similar products, which has the characteristics of sufficient power, safety and reliability, short construction period, and low installation cost.
The furnace is equipped with a cyclone burnout chamber, which reduces the dust content in the flue gas. At the same time, the hot carbon black particles are further burned, improving the thermal efficiency of the boiler and reducing the blackness of the flue gas. The smoke and dust emission concentration meets the requirements of a first-class environmental protection area.
The grate adopts patented technologies such as small roller structure and edge grate plates, greatly improving the reliability of boiler operation.
The closed type air chamber and double-sided furnace exhaust adjustment device are patented technologies protected by the state. They adopt a mechanically processed conical sealing structure to improve the sensitivity of furnace exhaust adjustment.
This series of boilers has been rated as first-class by the Ministry of Mechanical and Electrical Engineering, and is a national energy-saving promotion product and an excellent energy-saving product in Shandong Province.
According to user requirements, layered combustion devices and other energy-saving equipment promoted by the country can be matched.
