boiler gas circulation cape verde, ZOZEN boiler cooperates with jinguang paper to realize green production

China Academy of Space Technology is China's main space technology and product development base. Recently, the overall boiler system solution customized for the base by ZOZEN was highly efficient and environmentally friendly, which was more than 5% higher than the average measured thermal efficiency of conventional boiler systems in the industry. Therefore, ZOZEN won unanimous praise from the review experts, and finally realized the first cooperation with the China Academy of Space Technology, boiler gas circulation cape verde.

boiler gas circulation cape verde, The DHL series coal-fired corner tube boiler is field assembled boiler. It uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increasing.

Steam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. , Ltd. is one of large paper mill in Thailand. With the expansion of business and scale, the paper mill had to introduce extra sets of coal-fired steam boilers. ZOZEN supplied 15tph SZL series chain grate steam boilers for the company. This series of steam boiler features wide wide coal applicability and higher combustion efficiency.

The furnace of ZOZEN SZL series coal fired boilers adopts a close-packed a close-packed arrangement of water wall tubes. The application of close-packed water wall in furnace design changes the traditional structural form of the original industrial boiler furnace water-wall, effectively preventing high-temperature flue gas from scouring and radiating the furnace. Furnace radiation area is large, maintenance workload is small, overall weight is light.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality.

ZOZEN has proved its competitive advantage with its high product quality. In the future, ZOZEN will spend more time and energy on the innovation of gas-fired boilers, and capture more market share, boiler gas circulation cape verde.
