ZOZEN YLW series chain grate thermal oil boiler adopts the chain grate as the combustion equipment. It can provide high-temperature heat source at various temperatures below 350℃, achiving low-pressure and high-temperature heating for the processes of dyeing, drying, slashing, printing and dyeing, etc. In addition, this series of chain grate thermal oil boiler realize precise temperature control through an advanced oil temperature and oil pressure control system that greatly improves heat utilization, which meets the actual needs of textile companies.
The client is a small and medium-sized garment textile plant. Steam boiler, as a key equipment of textile production line, is widely used in textile, sizing, printing and dyeing, weaving and other links.
Nantong Everlasting Foodstuffs Co., Ltd. is a professional foreign trade enterprise, specializing in the production and processing of canned food. The steam boiler plays an irreplaceable role in the production of canned food. In order to ensure that canned food can be preserved for a long time without deterioration, it is necessary to sterilize the canned food with high temperature and high pressure steam. Therefore, a set of steam boiler system with stable operation, high efficiency and energy saving will directly affect the product quality.
Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
To meet Ningde Amperex Technology’s demands of production line reconstruction, ZOZEN Boiler designed the YQW series gas-fired thermal oil heater that could realize low-pressure and high-temperature heat supply and precisely control the temperature of heat medium oil to further guarantee the steady heat supply for the battery production line.
ZOZEN Boiler launched the oil-fired/gas-fired skid-mounted steam boiler in order to meet the demands from overseas market. The so-called skid-mounted boiler is to place all the boiler parts such as boiler proper, economizer, burner, valve & instrument, controlling cabinet, water treatment, economizer circulating pump, raw water pressure pump and so on together on one or two skid-mounted blocks to form a boiler system which can move orderly as a unit.
In order to meet the requirement of energy saving, environmental protection and sustainable development, Xinke Aode Technology decided to replace the existing coal-fired boiler with the environment-friendly gas-fired boiler. After learning about the outstanding comprehensive performance and good market reputation of ZOZEN boilers, Xinke Aode Technology reached cooperation with ZOZEN. ZOZEN recommended the SZS series condensing gas boiler for Xinke Aode Technology according to its actual requirements. This series of steam boiler adopts a large furnace and an advanced burner to ensure the complete combustion of the fuel and improve the fuel utilization. Besides, energy-saving devices are equipped at the end of the flue, which improves the thermal efficiency of the boiler to more than 98%. In addition, with an intelligent control system, the boiler can realize automatic operation and realize automatic adjustment of steam temperature and pressure, which achieves energy saving and consumpti
With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control. Meanwhile, when the system pressure exceeds the specified value, the full lift spring-loaded safety valve will be automatically opened to release pressure, which can avoid the accidents caused by excessive pressure. In addition,the chain grates of this series of boiler are all manufactured by ZOZEN. A 72-hours test run of the chain grates can ensure the moderate tightness of the grate. Besides, the scientific grate arch design, reasonable air distribution and governor box speed ensure the full combustion of biomass pellet fuel and the overall thermal efficiency of the boi
