Abstract

The utility model relates to a horizontal water pipe double grate open fire back-burning boiler which is composed of a boiler barrel, a circulation pipe, a collecting box, a fixing grate and a water-cooled grate. The utility model is characterized in that the upper layer of water pipes are a double-layer interlaced structure, and the oblique angle is 9 DEG. Besides, both ends of the upper layer of water pipes are respectively inserted in the front collecting box and the boiler barrel. The utility model has the advantages of compact structure, small size, small ground occupation, high thermal efficiency, convenient cleaning, low metal consumption, low smoke discharging quantity and high safety, and the horizontal water pipe double grate open fire back-burning boiler conforms to the requirement of the environment protection. The horizontal water pipe double grate open fire back-burning boiler is suitable for the disposition of mall-sized boiler rooms and is an ideal living and industrial boiler.

Description

Horizontal water pipe double grate open fire back-burning boiler

The utility model relates to a kind of for middle-size and small-size unit provides the boiler of life, factory steam and thermal source, is horizontal water pipe double-layer grate naked light back firing boiler specifically.

The boiler of same parameter mostly is vertical smaller hard flour pancake boiler or the horizontal chained furnace grate of extreme misery pipe both at home and abroad at present, the former is because the water-cooled degree is bigger, bunker coal is difficult for fully burning, so the thermal efficiency is low, latter's complex structure, the load undercapacity, floor space is big, and they all exist comparatively important disadvantages of environmental pollution.

The purpose of this utility model then is the problem at above-mentioned existence, and having designed a kind of upper strata water pipe is the horizontal water pipe double-layer grate naked light back firing boiler that double-layer grate is arranged.

The utility model technical solution:

A kind of horizontal water pipe double-layer grate naked light back firing boiler of forming by drum, circulation pipe, collection case, fixed grate, water-cooled grate, it is characterized in that the upper strata water pipe is double-deck shifted structure, its inclination angle is 9 °, and water pipe two ends, upper strata are inserted preceding collection case and drum respectively.

Advantage of the present utility model:

The utility model adopts the anti-combustion system that burns of double-layer grate naked light, has solved the problem of environmental pollution, and adopting the upper strata water pipe is that double-layer grate is arranged, can make full use of the heat transfer area of high-temperature region, 9 ° of inclinations of upper grate, double-deck stagger arrangement.The safe operation and this furnace grate tube that have guaranteed water-cooled grate clean easily, adopt the horizontal layout of DI.Make the heating surface compactness, the heating surface effective rate of utilization improves, thereby has reduced the metal consumption and the volume of unit significantly, is beneficial to the dilatation and the installation and operation in miniature boiler room, because whole unit is single whole square structure, be convenient to install with the boiler room in the layout of unit.

Fig. 1 is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model is further described:

Fuel adds on the upper strata water pipe double-layer grate 3 from firing door, through fierce burning and the second-time burning of charcoal material on fixed cast-iron fire grate 5 of leaking down, produce red-hot high-temperature flue gas, pool together through mixing fully, turn over wall with flues brick 6 by abnormity, flow to heated surface at the end of boiler through S type flue gas dividing plate again, in this process with Tao Daigang, upper strata water pipe double-layer grate 3 not only plays very big radiation heating-surface effect, but also has the effect that flue gas is produced big disturbance.

The water inlet of boiler is at drum 1 upside, upper strata water pipe double-layer grate 3 has good independent natural convection loop respectively with convection circulation pipe 2, preceding collection case 4 plays a part to compile with next part case 7, and working medium makes temperature, pressure parameter reach specified requirement through heating after the venthole discharge.

Structurally all pipe one ends are connected with the collection case, the other end is connected with drum, and drum is provided with the manhole device, guaranteed all good scale removal of each root pipe, corner in the convection bank of arranging by S type flow of flue gas all is being provided with shoot door, and for the removing of dust deposit in furnace provides condition, abnormity turns over the wall with flues brick and adopted the refractory brick, not only can stand washing away strongly of high-temperature flue gas, but also have higher intensity.

Claims

1, a kind of horizontal water pipe double-layer grate naked light back firing boiler of forming by drum, circulation pipe, collection case, fixed grate, water-cooled grate, it is characterized in that the upper strata water pipe is double-deck shifted structure, its inclination angle is 9 °, and water pipe two ends, upper strata are inserted preceding collection case and drum respectively.

2, horizontal water pipe double-layer grate naked light back firing boiler according to claim 1 is characterized in that abnormity turns over the wall with flues brick and adopts ceramic material.
