SU101813A1 - Engine with coal heating - Google Patents

Description

Significant forcing implemented in the steam furnaces, and the imperfection of the combustion process (limited furnace volume) leads to the fact that the amount of unbalanced particles of unburned fuel on steam locomotives with coal heating reaches 30%. Dust in chemical composition (regardless of coal grade) and uniformity of its particles is a good fuel for gasification. Disposal of ash increases the efficiency of a steam engine boiler.

According to the invention, a gas generator is installed on locomotives with coal heating for utilization of ash, the hopper of which is connected to the smoke box, and the gas pipe of the pipe with a burner in the furnace of the locomotive boiler. The smoke box of a steam locomotive is connected to the gas generator feed hopper by an automatic shutter, for example, controlled by a gravity force from the ground. The steam blowing device of the gas generator is connected to the exhaust pipe of a locomotive engine.

FIG. Figure 1 shows schematically a side view of the front part of a steam locomotive with a gas generator for exhaust; in fig. 2 - a type of a steam locomotive in front.

In front of the smoke box / there is a collection 2 for a more complete trapping of ash. Collector 2 is connected to the gas generator 3. Placed in front of the fire tubes, the flap 4 serves to direct the curtain from the front to the bunker. The exhaust pipe 5 of the locomotive machine is connected to the gas generator's jacket 7 by the steam pipe 6, and the latter to the confuser 8, which is placed under the grate 9. Between the collection container and the charging hopper of the gas generator, there is a spring-loaded valve 10. pipe connected to the steam engine to the steam engine.

Instead of a steam pressure controlled valve, an automatic shutter controlled by the force of gravity from the sun (not shown in the drawing) can be installed. In the gasification zone of the gas generator, there is a gas receiving pipe 12 connected to the gas exhaust pipe 13, with which the gas is supplied to the burner in the furnace of a locomotive boiler.

Izgar, carried away from the furnace of the boiler gas stream enters the smoke box. The gas flow rate in the smoke box drops sharply, resulting in the trapping of the ash that is collected in the collector. From the latter, it enters the gasifier feed hopper through a controlled

pressure steam valve or automatic shutter, opened under the influence of accumulated on it from the garden. The exhaust steam from the locomotive cone is partially sent to the gas generator shirt, and from there to the confuser. As a result of the ejection together With the steam under the grate of the gas generator enters the air. The gas produced in the gas generator is burned in the furnace of a locomotive, as a result of which the efficiency of the engine boiler is increased.
