Deicing technologies such as electromagnetism and laser are mainly applied to the fields of electric power, aerospace and the like. The mechanical deicing is mainly applied to the road and power transmission fields. In the field of fuel oil and gas power generation equipment, a large amount of combustion air and heat dissipation air are required to be inhaled when an engine works, in severe cold areas, when the temperature is low in winter and the ice and snow are more, the risks of freezing exist in an air inlet and a heat dissipation port frequently, and the operation safety of the engine is affected, so that the deicing equipment is often required to be added in a generator set used in the severe cold areas. For deicing of engines, electric and air heating are mainly used.
The gas turbine can generate a large amount of high-temperature gas due to the large air inflow, and the air can be led to the air inlet which is easy to freeze for deicing through intermediate air suction. Although the output of the unit is affected to a certain extent, the structure is simple, and excessive auxiliary equipment is not required to be additionally added. For diesel generating sets, because the power is lower, electric heating is generally adopted to heat the water tank part which is easy to freeze.

In order to solve the problem, in the market, for the engine used in severe cold areas, electric heating deicing equipment such as electric tracing rainproof shutters, electric heating tube windows and the like has to be additionally arranged, so that a large amount of electric energy is consumed, energy is not saved, and equipment investment cost is relatively large.
The heat in the exhaust of diesel engine accounts for more than one third of the total combustion heat of fuel, and the temperature is up to 350-550 ℃. For a high-power marine diesel engine, a waste heat boiler is often added in an exhaust pipeline, energy in the waste heat boiler is recovered, and the energy in the exhaust is converted into living hot water. The Denmark European Bao company has developed and designed integrated equipment combining waste heat boiler and exhaust muffler to make the product possess both heating and exhaust muffler functions, and this can save the installation space in ship greatly and is also one mature case for exhaust heat energy recovery. Therefore, the heat which is directly wasted after passing through the muffler is transferred to the inlet part of the radiator through proper heat exchange and mixing equipment to be deiced, so that the energy is saved and the safety is realized, and the method is an effective way for solving the problem of freezing of the diesel engine in severe cold areas.
