Flame heater is a kind of equipment that uses the heat energy generated by the combustion of flame to heat. It usually consists of a fuel supply system, an ignition system, a combustion chamber, a Heat Exchanger and an emission system. The fuel supply system usually uses liquefied gas, natural gas or diesel as the fuel, the ignition system is used to ignite the fuel, the combustion chamber is where the fuel is burned, the heat exchanger is used to transfer the heat generated by the combustion to the heated object, and the emission system is used to discharge the exhaust gas produced by the combustion. Flame heater is widely used in industrial production, construction sites, wild camping and other occasions, has the advantages of fast heating, high efficiency, easy operation and so on.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
