SU68972A1 - Concrete steaming device - Google Patents

Description

A distinctive feature of the proposed device is that it uses evaporative chutes, installed in the furnace flue and located below the floor of the steam chambers to drain condensate from the chambers directly into the chutes.

FIG. 1 shows the proposed device in longitudinal section; FIG. 2 is a plan of FIG. 1 and in FIG. 3 shows a partial right side view and a partial cut along the line A-A in FIG. one.

Two steaming chambers / are carried out in a block with an evaporation chamber 2, in which on reinforced concrete crossbars 3 the evaporating troughs 4 are hung with bolts with hooks. . At the other end, a manhole 6 for cleaning has been arranged against the end of the gutter. Against the lase B, it is arranged during mock 7, overlaid by planks 8 so that you can have access to the flue during cleaning.

At both ends of the evaporation chamber, there are hatches that are closed by iron double doors 9 with good insulation.

The evaporating chamber communicates with the steaming chambers using several windows W, the splitting chambers under the ceiling and equipped with new faucets 7 /. The evaporator is suspended with a small gap between the walls of the hog, and to avoid smoke seeping into the chamber, the gap is closed with an apron made of sheet iron around the perimeter of the chute. The apron with one edge is embedded in the masonry, and with the other it is lowered into the chute below the water level, thus forming a hydraulic shutter. In the steam chambers, trays / 2 are arranged in the floor along the walls, which are intercepted in the middle of the chamber by the transverse tray 13. The transverse tray enters the evaporator through the hydraulic shutter / 4, which prevents the steam from escaping into the steam chamber when the latter is isolated from the evaporator chamber above.

MJ-, liberal. The floor of the camera has a slope to the longitudinal trays.

A gas pipe is brought to the front of the furnace, on which KpFJToe waterglass / 5 glass is mounted. Here, the supply pipe of the water supply pipe 16 and the drain line, equipped with inlet valves and for the discharge of water, are mounted, as well as a cable run / 7 with a smoke gate / L. The furnaces 5 are located below the floor level in the heater. In the case of raw fuel in the furnace, it is arranged per fan 19.

The ash plant 20 is arranged behind the firebox, where soot is also scooped when cleaning the evaporator from.

The combination of the evaporative chamber with the open evaporator1 and the gland-arc chambers located adjacent to it in the same block would allow the steam boiler to be overloaded with overpressure, as steam,} that changes in the evaporator box .epe, rspii, a negligible increase; | black window 10 in the steam chambers, g ,, e warms up the camera with loading. Steam condensate flows to trays 12, and through them flows by gravity back to the evaporator. All heat losses to the environment, which reach 10% or more for small steam boiler, are reduced to zero in this installation, since the losses from the evaporation chamber along with the thin one go and the heating of the walls of the steaming caisley take into account the heat loss in the papr; kSslnyh installations, losses from,: lazy heat and heat transfer coefficient of heating surfaces, due to contamination with scale and soot, from which: -.: l5I in this design it is easy to heat, and the power consumption of condensate, then with}-.:.-. heat savings can be estimated not lower than in comparison with steam-boiler plants. It should also be noted the ease of cleaning the evaporators from soot and scale due to their full availability. Soot was removed from wire soled wire, worn on a gas pipe, which was driven through a separate pipe of 1.5 lg and cleaned using couplings. All the soot and ash is pounded up in the ashtray behind the firebox. Cleaning from scale, and repair is easy to make from inside the evaporation chamber.

Care of the evaporator consists in observing the water level on the water-meter glass and periodically replenishing, approximately once or twice a day. Losses of condensate will occur slightly. quantity only when cooling the camera, when unloading and loading. To produce an evaporator, any sheet of iron, about 3 mm thick, can be used. Care of the firebox can be entrusted to any boiler with proper instruction on fuel economy. Installation is not subject to boiler inspection.
