Product Introduction
The four-way fuel gas hot blast stove is a thermal power machinery. The four-way boiler was introduced in the boiler market in China in the 1990s. The four-way fuel gas hot blast stove has a wide variety and series, and has become a replacement product for electric heat sources and traditional steam power heat sources in many industries.
The four-way fuel gas hot blast stove is another new, efficient, and energy-saving heat exchange equipment that uses oil or combustible gas as fuel and air as heat transfer medium. Can continuously provide clean hot air with constant temperature, constant pressure, and dust-free (room temperature -350 ℃). The combustion chamber and heat exchanger of this hot blast stove are integrated, adopting a multi-layer sleeve structure made of all steel plates. The lower part of the furnace core is the combustion chamber, and the upper and surrounding parts are annular heat exchangers. The air and flue gas are both double return paths, each exchanging heat in its own way. To improve thermal efficiency, multi head spiral groove heat transfer technology is adopted and the flow is kept away, reducing the thickness of laminar flow and allowing air and flue gas to continuously exchange directions during movement, greatly enhancing heat transfer efficiency.
The combustion chamber and heat exchanger of the heater are made of imported heat-resistant steel and heat-resistant stainless steel, greatly extending the service life of the boiler. At the same time, the heater adopts an imported combustion chamber, which increases the reliability and guarantee of temperature automation control and thermal efficiency.
Performance advantages
(1) This hot blast stove introduces advanced technology and has a high degree of automation Strong reliability and precise temperature control. Adopting enhanced heat transfer methods and heat-resistant steel materials, the structure is compact, the volume is small, and the service life is long.
(2) Output clean hot air. The hot blast stove uses a heat exchange device to indirectly heat the air, allowing the flue gas and air to go their separate ways, heating without pollution, meeting the needs of applications that require clean, fire-resistant, and explosion-proof hot air.
(3) The output hot air temperature is high, and the high output temperature of the hot air stove can reach 550 ℃, which is difficult for both thermal oil heating furnaces and steam boilers to achieve.
(4) A hot blast stove directly delivers the flue gas from the complete combustion of different fuels to the heating equipment, which has a very high thermal efficiency, generally reaching an efficiency of ≥ 95, and an output temperature of up to 1000 ℃.
(5) Low operating costs, the hot blast stove directly outputs high-temperature air through one heat exchange, with high thermal efficiency, making up for the shortcomings of low thermal efficiency caused by secondary heat exchange in steam boilers and heat transfer oil heating furnaces, saving fuel and electricity. Compared with some electric heating drying methods, it is only one-third of the operating cost of electric heating. Therefore, the electric heating and drying room system can be renovated, and the renovation cost can be recovered within six months to one year, with significant economic benefits.
(6) The initial investment is low, and it can be installed or erected on the top, bottom, or one side of the heating equipment without the need for an additional furnace room. With the same equipment material and heating capacity, its initial investment is much more economical than that of thermal oil furnaces and steam boilers.
(7) Users can choose heat exchange devices with different performance such as cylindrical, tubular, or plate type according to the operating temperature and layout conditions.
