Description
Technical Field
The utility model relates to a fuel air heater field, in particular to be applied to heat exchanger of air heater of indirect burning.
Background
The oil and gas air heater is mainly used for heating large-space places such as industrial and commercial places, buildings, bridges and the like, and can also be used for drying industrial products. It can provide clean dry hot-air, heats whole space, and the temperature is even, has the heating rapidly, the fast advantage of heat circulation.
The mobile indirect-combustion fuel oil and gas air heater generates heat through combustion of fuel oil or gas, the heat exchanges the heat for the ventilator through the heat exchanger, the heat exchange efficiency of the heat exchanger can influence the operating cost of a user, the efficiency is higher, the burning fuel is less, and therefore the improvement of the heat exchange efficiency of the air heater has important significance for the development of the air heater.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model discloses a be applied to indirect burning's heat exchanger of air heater, the technical scheme of the utility model is implemented like this:
the utility model provides a be applied to heat exchanger of air heater of indirect burning, includes the casing, outer heat exchanger is installed to the casing inboard, the combustion chamber is installed to outer heat exchanger inboard, the combustor installing port is installed to combustion chamber one end, the combustor installing port is used for being connected with the combustor, the combustion chamber with connect through air conduit between the outer heat exchanger.
Preferably, a space is arranged between the combustion chamber and the outer layer heat exchanger
Preferably, the heat exchanger applied to the indirect-combustion air heater further comprises an exhaust port, and the exhaust port is mounted at the upper end of the outer side of the shell.
Preferably, the number of the air ducts is 1 to 4.
Preferably, the housing is cylindrical.
By implementing the technical scheme of the utility model, the technical problem of low heat exchange efficiency of the hot air blower in the prior art can be solved; according to the technical scheme of the utility model, a space is arranged between the combustion chamber and the outer heat exchanger, the temperature of the combustion chamber is highest, and when the combustion chamber is used for combustion heating, the combustion chamber exchanges heat with external air through the space between the combustion chamber and the outer heat exchanger; high temperature air in the combustion chamber enters into outer heat exchanger through air conduit simultaneously, and outer heat exchanger's inside and outside two sides can carry out the heat transfer with the outside air simultaneously, and heat exchange efficiency improves, just the utility model discloses simple structure, the cost is lower.
