(1) Start-up temperature The cold diesel engine must be started at the lowest possible diesel engine speed and low ambient temperature.
The lower the diesel engine speed, the lower the final compression pressure and the lower the resulting temperature in the cylinder. At the same time, the reduction of the battery voltage at low temperatures also reduces the starting speed.
(2) Thermal diffusion and leakage Operating temperatures that do not meet the operating requirements of the piston ring can cause leakage. The cold diesel engine has thermal diffusion in the compression cycle. For diesel engines with separate combustion chambers, the thermal diffusion is severe due to the large surface of the combustion chamber.
(3) Friction loss The friction force of the mechanical components of the diesel engine is greater at the low temperature than at the normal operating temperature. As the temperature increases, the fluidity of the diesel engine oil increases, and the fitting clearance of the mechanical components also decreases.
(4) Fuel Regulation Fuel heating through the filter or direct heating of the fuel can avoid fuel problems at low temperatures due to paraffin wax crystallization. For modern diesel fuel, this problem only occurs when the temperature is below -25°C.
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.
