Abstract
The utility model relates to a fuel gas blast stove, in particular to a novel fuel gas blast stove with high heat exchange efficiency, and solves the problems like low heat exchange efficiency of the present fuel gas blast stove. The novel fuel gas blast stove includes a combustor, a stove body, and a combustion chamber arranged in the stove body, wherein a fire inlet of the combustion chamber is arranged at the front part of the stove body, and a flame outlet of the combustor is fixed with the fire inlet of the combustion chamber; an air supply outlet at the rear part of the stove body and an air outlet on a stove top at the front part of the stove body are arranged on the stove body; the combustion chamber is wound by a spiral flue communicated with the inside of the combustion chamber and the outside of the stove body, a flue inlet of a joint of the spiral flue and the combustion chamber is placed at the chamber top at the front part of the combustion chamber, a flue outlet of a joint of the spiral flue and the combustion chamber is placed at the chamber top at the rear part of the combustion chamber, and spaces as wind channels are reserved between the spiral flue and the outer wall of the combustion chamber, and between the spiral flue and the inner wall of the stove body. The structure is reasonable and compact, the using effect is good, the heat exchange efficiency is high, and the novel fuel gas blast stove can be widely used in fields like grains, tobacco drying, freeze protection for coal mine shafts in winter, etc.
Description
Technical field
The utility model relates to fuel gas hot-blast stove, is specially a kind of novel gas hot-blast stove with high heat transfer rate.
Background technology
The structure of existing fuel gas hot-blast stove is more single, especially on heat exchange mode, adopts fuel after combustion chambers burn more, and flue gas is just directly discharged through behind the pipe type heat transfer of 2-3 backhaul; Heat exchange efficiency is relatively low, and the heat exchange structure heaviness, and it is bigger to make that hot-blast stove integral body takes up room, and also has of short duration, drawback such as maintenance inconvenience etc. in service life simultaneously.
Summary of the invention
The utility model provides a kind of novel gas hot-blast stove in order to solve problems such as the heat exchange efficiency that has the fuel gas hot-blast stove existence now is low.
The utility model is to adopt following technical scheme to realize: the novel gas hot-blast stove, and comprise burner, body of heater, be set up in the combustion chamber in the body of heater, the burner that advances of combustion chamber is arranged at the body of heater front portion, and the burner that advances of the flame-out port of burner and combustion chamber is fixed; Body of heater is provided with the air outlet that is positioned at the body of heater rear portion, the air outlet that is positioned at the anterior furnace roof of body of heater; Have around the home outside the combustion chamber and be communicated with in the combustion chamber and the outer spiral flue of body of heater, the flue entrance of spiral flue and junction, combustion chamber is positioned at top, anterior chamber, combustion chamber, the flue outlet of spiral flue and body of heater junction is positioned at body of heater rear portion furnace roof, between spiral flue and the outer wall of combustion chamber, leave between spiral flue and the inboard wall of furnace body as the space of crossing the wind passage.
The course of work is as follows: combustion gas fully mixes with air, after burner is lighted, blasting fully burns in the combustion chamber produces high-temperature flue gas, high-temperature flue gas enters from the chimney intake that is positioned at top, anterior chamber, combustion chamber and is looped around combustion chamber spiral flue on every side, discharges from the flue outlet that is positioned at hot-blast furnace body rear portion furnace roof; And cold wind is sent into from the air outlet at hot-blast furnace body rear portion by pressure fan, through between spiral flue and the outer wall of combustion chamber, between spiral flue and the inboard wall of furnace body cross the wind passage time, carry out heat exchange with combustion chamber, spiral flue, being heated becomes hot blast, discharges from the air outlet that is positioned at the anterior furnace roof of hot-blast furnace body and transports to the user.
Compared with prior art, the utlity model has following characteristics: 1, adopt the spiral flue, make high-temperature flue gas second backhaul carry out heat exchange along the spiral flue that is looped around outside the combustion chamber, compared to calandria heat exchange in the past, not only manufacturing cost reduces, and longer service life is of a specified duration, and Maintenance and Repair are also more convenient; 2, owing to simultaneously carry out the secondary heat exchange with combustion chamber and the spiral flue that is looped around around the combustion chamber, cold wind stops in hot-blast furnace body and can heat up the thermal efficiency height blink rapidly; 3, compare with existing same size hot-blast stove, volume is obviously less, installs, transports, moves, disassembles very convenient.
The utility model is rational in infrastructure, compact, and result of use is good, and the heat exchange efficiency height can be widely used in the oven dry of grain, tobacco, and field such as mine shaft preventing freeze in winter.
