Abstract

The utility model relates to a boiler, particularly a novel horizontal fuel oil boiler. The tail section of a corrugated boiler chamber (2) in a shell (1) is provided with holes and is assembled with a bent fire tube (6), and high-temperature smoke is returned from the bent fire tube at the tail section of the corrugated boiler chamber to a second return stroke straight smoke tube (4). The utility model has the advantages of reliable combustion, stable operation of a rear smoke box, low smoke exhaust temperature and high heat efficiency of a traditional wet back type oil fuel boiler, and has the advantages of small steel consumption, simple production process, low cost and convenient maintenance of a dry back type oil fuel boiler. Compared with a traditional wet back type oil fuel boiler, 40% of the steel consumption can be saved, the smoke exhaust temperature is lower and the heat loss is smaller.

Description

The novel horizontal oil burning boiler

The utility model relates to a kind of boiler, particularly a kind of novel horizontal oil burning boiler.

In the existing horizontal oil-firing boiler, evaporation capacity is on 2 tons/more than per hour the traditional wetting back-type structure of all employings (as shown in Figure 1), the afterbody of the corrugated internal furnace (2) in the shell (1) is provided with flue gas rotary chamber (3), make high-temperature flue gas be turned back to the straight smoke pipe of second backhaul (4) in that flue gas rotary is indoor, and obstructed smoke box (5) later.The advantage of the boiler of this structure is: burning is reliable, back smoke box working stability, exhaust gas temperature is low, the thermal efficiency is high.Its weak point is that the consumption of steel is bigger, complex manufacturing, cost are higher, and its particular manufacturing craft just reaches more than 5 pairs (10), is difficult to be suitable for the low capacity boiler.And evaporation capacity is 0.5-1.5 ton/dried back of the body formula structure (as shown in Figure 2) that all adopts hourly, corrugated internal furnace (2) in shell (1) links with the flue gas rotary chamber (3) that is located in the back smoke box (5), makes flue gas rotary indoor the be turned back to second backhaul straight smoke pipe (4) of high-temperature flue gas in being located at the back smoke box.The advantage of the boiler of this structure is: the consumption of steel is little, production technology is simple, cost is low, easy to maintenance, its weak point is that back smoke box temperature is too high, burnt out easily and caused very big economic loss to the user, its exhaust gas temperature is also than higher simultaneously, generally more than 340 ℃, heat loss is bigger.

The purpose of this utility model is intended to overcome the above-mentioned weak point of prior art and a kind of novel horizontal oil burning boiler is provided.

The technical solution of the utility model is: the curved fire tube of perforate and assembling on the corrugated internal furnace rear in shell, and make high-temperature flue gas in the curved fire tube of corrugated internal furnace rear, be turned back to the straight smoke pipe of second backhaul, and obstructed smoke box later.

The further technical scheme of the utility model is: smoke box behind the back smoke box employing water-jacket typ.

The utility model is owing to adopt as above design, compared with prior art, both had that wetting back-type oil burning boiler burning is reliable, back smoke box working stability, exhaust gas temperature is low, the thermal efficiency is high advantage, has the advantage that dried back of the body formula oil burning boiler steel consumption amount is little, production technology is simple, cost is low, easy to maintenance again, steel consumption saves about 40% than traditional wetting back-type oil burning boiler, exhaust gas temperature is low, and heat loss is little.

Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.

Accompanying drawing 1 is the structural representation of traditional wetting back-type horizontal oil-firing boiler;

Accompanying drawing 2 is the structural representation of dried back of the body formula horizontal oil-firing boiler;

Accompanying drawing 3 is a structural representation of the present utility model.

Embodiment: as shown in Figure 3, the novel horizontal oil burning boiler is perforate and the curved fire tube (6) of assembling on corrugated internal furnace (2) rear in shell (1), make high-temperature flue gas in the curved fire tube (6) of corrugated internal furnace (2) rear, be turned back to the straight smoke pipe of second backhaul (4), and obstructed smoke box later, and smoke box (7) behind the back smoke box employing water-jacket typ has cooling water (8) in it.

Claims

1, a kind of novel horizontal oil burning boiler is characterized in that perforate and the curved fire tube of assembling on the corrugated internal furnace rear in shell.

2, boiler as claimed in claim 1 is characterized in that thereafter smoke box adopts smoke box behind the water-jacket typ, has cooling water in it.
