Due to the vastness of China’s territory, there is still a considerable market for small-capacity industrial boilers in rural and urban areas outside the large and medium-sized cities. In recent years, the rapid development of the real estate market across the country has led to an increase in demand for large-capacity hot water boilers with a capacity of 35t/h or more. The basic reason for high-temperature coke is that the carbon content in the fuel layer exceeds the amount of heat balance required. Circulating fluidized bed boilers belong to low-temperature combustion, so their NOx emissions are far lower than those of coal-fired boilers, only about 100mg, and they can realize in-situ desulfurization during combustion, with a high desulfurization efficiency. The circulating fluidized bed boiler is divided into two series, SHX, and DHX, both of which retain the technical advantages of low-temperature combustion of circulating fluidized bed boilers, adjust the ratio of first and second air, optimize the arrangement of second air, reasonably design the furnace hearth heat-absorbing surface, and control the bed temperature at 860-880℃ to effectively control the emission of NOx. Compared with other environmental protection boilers that reduce NOx emissions by adjusting the burner, circulating fluidized bed boilers fundamentally solve the problem of high NOx concentration.

Do small boilers have blast furnaces? Boiler energy saving is a kind of technology. It can improve the thermal efficiency of the boiler and make the thermal efficiency of the boiler reach a higher level, saving 10%-15% of coal. Boiler energy saving is achieved through the intelligent control system of boiler informatization and energy saving, which automatically controls the draught fan, blower, grate, water pump, and other parts of the boiler equipment, so as to achieve the effect of improving the thermal efficiency of the boiler.
The YQW series heat transfer oil boiler has attracted the attention of Dongfang Science and Technology due to its advantages in product quality, performance and environmental protection effects. The welding technology of this series of heat transfer oil boilers is advanced, and all welds are X-ray real-time imaging and 100% pressure tests to prevent unqualified welds from entering the production line; the boiler body adopts a three-stage ring pipe structure with sufficient heat absorbing surface, and the installation of an energy-saving device at the end of the boiler body can ensure a thermal efficiency of over 95%; advanced fuel burning equipment can achieve low NOx emissions.
