Abstract

The utility model relates to a pulsating combustion heating furnace belonging to a heating device, and comprising a burner and a furnace tube bank which are arranged in a furnace shell and a smoke flue, wherein an air supply buffer room is arranged at the front end of the furnace shell, an outlet pipe of a blower fan is connected with the air supply buffer room, a burner is placed at the front end in the furnace shell, a compressed air inlet pipe communicated with the air supply buffer room, an electronic igniter and a gas inlet pipe are arranged at the inlet end of the burner, a tubular furnace tube bank connected with a decoupling device is arranged at the outlet end of the burner, and the decoupling device passes through the smoke flue and is evacuated via a muffler, and a material feeding opening a and a material discharging opening b are arranged on the furnace shell. The pulsating gas-fired boiler is a novel heating device, and the gas entering in the combustion chamber is burnt in a pulsating way. The heat after burning is transmitted to external medium through the combustion chamber, a furnace tube, the decoupling device and an air exhaust pipe. The heating device has the advantages of high combustion efficiency, combustion intensity and heat exchange performance and long service life.

Description

Intermittent combustion heating furnace
Technical field
The utility model belongs to heater, particularly relates to a kind of intermittent combustion heating furnace.
Background technology
It is indispensable process procedure in the crude oil production that crude oil in China oil field adds the conveying of (heat) water.Guarantee at present major technique means that this link realizes to be to use with the natural gas be fuel, adopt routine heating (stove) equipment of stable state combustion mode, as the water-jacket typ heating furnace etc.In order to improve the thermal efficiency of these firing equipments, the many research institutions and the unit in domestic oil field have carried out unremitting effort, strengthen heat exchange area as increase finned tube in flue, adopt efficient nozzles, adopt hot pipe technique, adopt negative pressure or pressurized firing and phase change technique or the like.The thermal efficiency is corresponding to have obtained certain raising though these The Application of Technology make, but also correspondingly brought the problems such as manufacturing cost increase that can't overcome, and brought investment cost to increase and also problem such as corresponding increase of equipment maintenance cost for thus the oil field crude oil production.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of efficiency of combustion high intermittent combustion heating furnace.
The utility model intermittent combustion heating furnace be in furnace shell, establish burner and boiler tube group, flue constitutes, the front end of furnace shell is provided with the air-supply surge chamber, fan outlet tube connects the air-supply surge chamber, burner places the front end in the furnace shell, the arrival end of burner is provided with the compress wind inlet tube and is communicated with, has electronics device for igniting, fuel gas inlet pipe with the air-supply surge chamber, the port of export of burner has shell and tube boiler tube group to be connected with decoupling device, decoupling device through the muffler emptying, is provided with material gateway a, b by flue on furnace shell.
As further improvement of the utility model, be divided into burning zone A and heat release section B before and after the burner, its port of export is dome head C.
As further improvement of the utility model, an end of each boiler tube of boiler tube group becomes radiation to be connected with the circular arc sphere of dome head C, and the other end is shell and tube again and is connected with decoupling device.
Intermittent combustion is the special combustion process of a kind of periodically pulsing different with smooth combustion, is a kind of efficient energy-saving, oligosaprobic high-new combustion technology.The intermittent combustion firing equipment is to be the device that core component heats medium with the pulsating combusting device, and the operation principle of its core component pulsating combusting device is as follows:
After air in certain amount (passing through blower fan) and fuel gas (natural gas) enter the combustion chamber, light through mixing by electronics point combustion gas sparking.After lighting, burning indoor temperature, pressure raise rapidly, thereby air valve and fuel valve have been closed, combustion product is discharged at a high speed along boiler tube, under the exhaust effect of inertia, is pumped into negative pressure in the combustion chamber, fuel valve and air valve are opened, air, fuel are inhaled into the combustion chamber and are lighted (after this no longer need spark ignitor, also no longer need blower fan air-supply) by the ashes that burnt last time, the formation intermittent combustion that goes round and begins again of the burning in the combustion chamber like this.
The pulsation gas fired-boiler is a kind of novel firing equipment.By a kind of special construction, the combustion gas that enters the combustion chamber is burnt with the form of pulsation.The heat that the burning back produces passes to external agency by combustion chamber, boiler tube, the device of uncoupling, blast pipe.This firing equipment has efficiency of combustion height, combustion intensity height, heat exchange property height, scratch the stream plate and the heat release chamber can realize whole pulsating combusting device Temperature Distribution is regulated control by in traditional pulsating combusting device, installing, significantly reduce boiler tube and junction, combustion chamber temperature, solve the partial failure problem, thereby greatly improve the intermittent combustion heating furnace life-span.
