Abstract

The utility model discloses a new boiler machine, and structural styles with convex-concave shape bodies are harmoniously distributed on a fire box, a smoke tube and a generating tube of an original boiler machine according to a notice. The utility model has the advantages of reducing the integral volume of the boiler, increasing evaporation quantity, improving the convection current time and the flame detouring time of complete-machine thermo-molecule and enhancing heat exchanging efficiency.

Description

The New-type boiler machine

The utility model relates to a kind of boiler machine that is used to heat or drives locomotive.

At present it is very clumsy for the boiler machine that uses, and it is long-pending huge to account for fermentation, and this transportation and installation to boiler machine brings very big difficulty, and boiler machine efficient is low, and the water in its boiler needs could cross needed temperature for a long time.According to statistics, advanced locomotive boiler gross efficiency has only 54%-60%.After except the loss such as combustion gas discharge, scarp, imperfect combustion, slag, boiler, boiler heat radiation, the efficient of it has only 70%.The evaporation capacity of boiler is subjected to the restriction of multiple factors such as boiler design, fire-box heat transfer area, smoke pipe heat transfer area, hearth area again, so that has influenced boiler to rate of energy, needs further to improve.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of volume and Coal-fired capacity of reducing is provided, the New-type boiler machine that increases evaporation capacity and raise the efficiency.

The purpose of this utility model realizes by following measure: it is that fire-box, smoke pipe and generating tube body at original boiler machine has the version of convex concave shape body by equidistant evenly the distribution.Both dwindle the boiler overall volume, can increase evaporation capacity again, improved the convection current time and the circuitous time of flame of complete machine thermo-molecular, the heat exchanger effectiveness height.

The design of New-type boiler machine can change and dwindle the volume of former boiler machine own, and the gap between boiler shell and the fire-box, improves the evaporation capacity that changes it.Can improve the boiler internal heat conductivility rapidly, reduce heat-energy losses, increase work efficiency and service life.

Embodiment is further described below in conjunction with accompanying drawing.

Fig. 1 is a New-type boiler machine structural representation.

Fig. 2,3,4,5 is that the example structure of Fig. 1 is launched schematic diagram.

Belong to the horizontal boiler machine by New-type boiler machine shown in Figure 1, it installs a fire-box 4 by the inner chamber of boiler body 1, the casing of fire-box 4 is a convex-concave shape body, the smoke pipe 3 that its fire-box 4 one ends have is the convex-concave shape equally, be communicated with fire-box 4 and smoke box 10 respectively, be positioned at arch brick 9 that the fire-box 4 of fire door 8 is provided with and the generating tube 7 that has the convex-concave shape, and boiler shell 1 inside respectively with the shell body of smoke pipe 3 and fire-box 4 on the tube stay 2 that is provided for gaining in strength and back support 6 and shore 5.

Above-mentioned fire-box 4, smoke pipe 3 and generating tube 7 bodies adopt same convex-concave shape body, and its shape can be by waiting the equally distributed arc shape of square, waveform shape or zigzag, shown in Fig. 2,3,4.This convex-concave shape body can reduce the monnolithic case size, increases evaporation capacity, improves the evaporation heat transfer area, has dwindled the gap between boiler shell 1 and the fire-box 4, the convection current time of director's thermo-molecular and the circuitous time of flame, improves rate of heat exchange.

As shown in Figure 5, the fire-box that it provides, smoke pipe and generating tube all can be had conducting strip 11 by the axial distribution of body, can improve the heat conductivility of boiler internal fast by conducting strip 11, improve heat exchanger effectiveness.

Technology of the present utility model is removed for the convex-concave shape on fire-box 4 bodies of horizontal boiler machine, can be the axial distribution along fire-box 3 bodies.And change also suitable accordingly for the vertical boiler machine.The same convex-concave shape that adopts on the fire-box body of vertical boiler machine, its convex-concave shape should be by the fire-box radial distribution.Can reduce the whole height of boiler machine like this, not reduce evaporation capacity again.

Claims (3)

1, New-type boiler machine, the smoke pipe that comprises boiler shell and interior setting thereof is communicated with fire-box, the arch brick and the generating tube that are equipped with in the fire door place fire-box body, it is characterized in that the integral body of described fire-box (4) and smoke pipe (3) and generating tube (7) body are a convex-concave shape body, each convexconcave part can form by equidistant evenly the distribution.
