The object of the present invention is achieved like this: heat storage coal gas pipe radiator combustion engine is the same with common radiation combustion engine, the radiator tube profile is U-shaped or W shape, its main part is mounted in the combustion unit at radiator tube two ends, and combustion unit mainly is made up of burner, air/flue, gas line and the reversing valve that matches with it; Special feature of the present invention is: the inner chamber of the front end U/W shape of the radiator tube of this combustion engine part is a combustion chamber, and its rear end two straight-tube portion inner chambers are provided with secondary gasburner and heat storage, the work that hockets of the secondary gasburner at two ends and heat storage; Two straight-tube portion central authorities are provided with gas pipe, and gas pipe passes heat storage, and its front end links to each other with the secondary gasburner; Gas pipe central authorities also are provided with the ignition channel that long-range igniting kindling material is delivered to the secondary gasburner, the ignition channel front end secondary gasburner that goes directly, and the rear end links to each other with the remote spots firearm; The coal gas reversing valve joins with the gas pipe of two straight tube rear ends respectively; Air/flue gas reversing valve joins with air, the fume pipe of two straight tube rear ends respectively, and the temperature detection galvanic couple is arranged on the flue gas house steward, and the microcomputerized control box is arranged in the combustion engine shell.
The gas pipe central authorities that are provided with fin and heat storage in the pipe also are provided with the ignition channel that long-range igniting kindling material is delivered to the secondary gasburner, the ignition channel front end secondary gasburner that goes directly, and the rear end links to each other with the remote spots firearm;
The remote spots firearm of this combustion engine is the airtight cavity of a long tubular, along the kindling material working direction, is disposed with gas inlet, igniting airduct, high pressure spot duration and degree of heating in the lighter for ignition chamber.
The lighting up procedure of described combustion engine remote spots firearm is as follows:
A, at firing tip, the opening pressure air purges 10-30 second;
B, start the high pressure spot duration and degree of heating and make the generation electrical spark, start gas inlet immediately, the start time of coal gas, electrical spark continued 6-8 second than the slow 1-2 of electrical spark second, and it is 30-60 second that coal gas is supplied with combustion time;
C, air/flue gas reversing valve and coal gas reversing valve commutate, and begin preparation work at the other end of radiator tube;
D, at another firing tip, adopt pressure air to carry out the 10-30 purging in second earlier equally;
E, start the high pressure spot duration and degree of heating and make the generation electrical spark, start gas inlet immediately, the start time of coal gas, electrical spark continued 6-8 second than the slow 1-2 of electrical spark second, and it is 30-60 second that coal gas is supplied with combustion time;
F, a work period finish, and next work period begins; Go round and begin again, carry out above operation, when showing that to detected result the discharge flue-gas temperature reaches design temperature (150-180 ℃), stop ignition operation.
Described coal gas reversing valve, air/flue gas reversing valve are three the seven logical rotation switching valves that air/flue gas, coal gas can switch synchronously.
Described heat storage is ceramic honeycomb body, steel alloy honeycomb.
Technical solution of the present invention novelty, reasonable, simple in structure, obtained technique effect is obvious.It all becomes one heat storage, secondary gasburner, coal gas reversing valve, air/flue gas reversing valve, remote high-voltage lighter for ignition and microcomputerized control, the temperature detection indicating meter of heat storage type combustion, be a kind of efficiency of combustion height, safety, the radiator tube combustion engine that operation life is long.Owing to all be provided with heat storage and secondary gasburner in two straight tubes, burning of alternative expression ground, two ends and accumulation of heat can bring the air preheating temperature height, the temperature of combustion height, and radiator tube is heated evenly, a series of technical superioritys such as thermo-efficiency height.The invention of long-range gas igniter has changed traditional sparking mode, has avoided the high temperature scaling loss of portfire, has also exempted many difficulties of changing portfire.Since above advantage, the work-ing life of also directly having improved combustion engine.
