Facing the long and severe winter climate in Northern China, the reliability and energy efficiency of heating systems are crucial. This gallery showcases several central heating project sites in Northern China, all of which have selected the SZS series gas-fired hot water boilers manufactured by ZOZEN Boiler as their core heat source. As a key product of ZOZEN Boiler, the SZS series features a double-drum longitudinal layout and a large furnace design, combined with low-nitrogen combustion technology. This not only effectively reduces NOx emissions but also ensures high-efficiency conversion of thermal energy. With excellent product quality and comprehensive after-sales service, ZOZEN Boiler delivers continuous and stable warmth to thousands of households during the cold winter, becoming a trusted partner for many heating enterprises.
ZOZEN Boiler’s SZS series gas-fired hot water boilers adopt a full membrane-wall structure and a large combustion chamber. Combined with advanced low-NOx combustion technology, they raise thermal efficiency while meeting stringent environmental emission standards. Widely used in district heating, industrial park heat supply, and commercial complexes, the series delivers a reliable heat source through stable operation and an intelligent control system.
The debugging of biomass boiler is an important step to ensure the stable and economic operation of the boiler, which is time-consuming and labor-intensive, with high technical requirements. ZOZEN service personnel gave on-site guidance, first of all, cold commissioning of biomass boiler, and cold calibration of boiler body water pressure test, pressure gauge, flow meter, safety valve and various interlocking protections.
ZOZEN is a large industrial boiler manufacturer specializing in the supply of oil-fired boilers, gas-fired boilers, biomass-fired boilers, coal-fired boilers, circulating fluidized bed boilers and organic heat carriers. ZOZEN pays special attention to product quality, and introduces 600 sets of advanced tooling equipment to realize large-scale and modern production.
The autoclaved curing process of building materials in the project needs a lot of steam support, and requires stable steam supply. ZOZEN technicians designed a set of biomass boiler that is not easy to coke and accumulate ash. By adjusting the internal structure of the boiler and changing the arrangement of the drum, the dust in the flue gas can directly settle into the ash hopper at the bottom of the convection zone when the flue gas enters the convection zone from the furnace outlet.
ZOZEN provides a set of 15 tons superheated steam boiler for a paper making company in China. The boiler is the SZS series, it is designed with the superheater to raise the temperature to meet the demand.
The ASME boiler standard of the American Society of Mechanical Engineers is an internationally recognized authoritative boiler regulation and is widely used. Holding the ASME certificate is also a strong proof that an enterprise's management and technology have reached the international level. In 2007, ZOZEN took the lead in obtaining the ASME stamp and authorization certificate in the industry, taking a big step towards the international market. The biomass boiler is produced in strict accordance with ASME standards and meets the needs of users.
The fully assembled ZOZEN 30 tph SZS gas-fired steam boiler is displayed. The rated evaporation capacity of this gas-fired steam boiler is 30 tons per hour, the pressure is 1.25, 1.6, and 2.5MPa, and the heating temperature is 194°C, 204°C, and 225°C. It is suitable for various industries such as chemical industry, food, and medicine.
