oil thermal boiler design calculations, senior industrial boiler designer of ZOZEN boiler answers your questions

2020 is the start year of the construction of ZOZEN Boiler’s lean factory. As one of the key tasks of this year, based on the successful application of MES (manufacturing enterprise production process execution management system) informatization, ZOZEN Boiler will adhere to the lean management concept to build the digital lean factory, and implement the standardization of operation and workflow in every process of production and operation.

The after-sales service of boilers is the issues that users are very concerned about. ZOZEN is fully aware that in the current time when the homogenization of boiler products is serious, after-sales service is the core competitiveness to effectively open the gap between various boiler manufacturers. In the face of every problem encountered in the use of users' boilers,ZOZEN will regard it as their own responsibility, establish a comprehensive after-sales mechanism, responds quickly, and effectively solve problems for users.

ZOZEN YLW series thermal oil heater is a kind of horizontal square-coil chain grate boiler. It is pre-assembled, so the chain grate and boiler proper are separated for shipment. The boiler adopts the chain grate for mechanical coal feeding, the forced and induced draft fans for mechanical ventilation and the slag discharger for mechanical slag discharge. During operation, the fuel falls from the coal hopper onto the grate for combustion. The high-temperature flue gas is reflected from the back arch to the front of the furnace and enters the furnace. After the radiant heat exchange, it enters the convective heating surface for convective heat exchange and then goes to the waste heat boiler, air preheater and dust collector. Finally, the flue gas is drawn by the induced draft fan through the chimney and is discharged into the atmosphere.

oil thermal boiler design calculations, The grate bracket adopts double brackets, the lower channel steel, the upper light rail, the upper heat, the lower force, which has changed the structure of the traditional grate bracket angle steel plus friction bar, the grate bracket is not deformed. The active stoker is operated on the light rail and it is tested in the cold state for 48 hours before leaving the factory. Never run sideways, stuck, which ensure the smooth operation of the stoker.

The cold working, also known as “iron tailor”, is a kind of comprehensive technology to process metal sheet material, tubular product and proximate matter into various kinds of products without changing the cross section characteristics, which includes straightening, laying off, blanking, cutting, bending, stamping, assembling, riveting, welding, etc. At ZOZEN’s production lines, the number of cold working workers is the largest except that of welding workers.

According to the actual production demands of Lenzing (Nanjing) Fiber Co., Ltd., ZOZEN Boiler recommended the SZS series gas-fired superheated steam boilers. This series of steam boiler adopts the large-volume furnace to ensure the sufficient fuel combustion. Combined with an advanced low-NOx burner, it can easily achieve the low emission of NOx, which meets the environmental protection requirements of Lenzing Group. At the same time, in order to improve the boiler thermal efficiency, it not only uses the high-quality aluminum silicate fibers for the furnace body, but also uses high-temperature refractory mud for heat preservation. With the additional energy-saving equipment at the end of the flue gas duct, the boiler thermal efficiency is as high as 98% to save the operating costs, oil thermal boiler design calculations.

In the future, ZOZEN Boiler will further expand the business in the Colombian market, and use Colombia as the entry point to gradually radiate markets in Brazil and Chile, which is expected to open up a new situation in the South American market. Meanwhile, in the boiler industry, the good performance of ZOZEN Boiler in overseas markets has also played a positive role in promoting the high-end and international image of ZOZEN brand to further consolidate the leading position in energy-saving and eco-friendly boiler field, which provides a set of good development ideas for Chinese boilers and even Chinese brands to go to the world.
