2 Claims. c1. 126--271.2)
My invention relates to a heating device and more particularly to a fluid fuel burner for protecting newly poured concrete from freezing, and for curing.
My invention has for its object the provision of an improved heating unit that is suitable for heating and curing newly laid or poured concrete, in confined spaces such as under a tarpaulin.
Another object of my invention is to provide a heater of the character referred to which can be taken apart and transported conveniently.
Still another object of my invention is to provide a heater that is effective to utilize the maximum of heat from a fluid fuel burner, without danger of damage to a covering sheet or in too close contact with the cement, and wherein maximum efliciency is obtained from the heat.
One form which my invention may take is shown on the accompanying drawing wherein:
Figure 1 is a side elevational view of the unit.
Fig. 2 is an enlarged sectional view of the air intake chamber and the combustion chamber of Fig. 1.
Fig. 3 is an end view thereof.
Fig. 4 is an end view of Fig. 1.
The heater comprises thin wall tubes 5 and 6 that are supported on legs 7, 8 and 9, either loosely, for disassembly, or welded to said legs. The pipe sections 5 and 6 are provided with handles 10 and 11 respectively and are detachably held in alignment with one another by cleat-like bars 12 which will be welded to one of the pipes and fit telescopically into the other pipe, whereby the pipes can readily be assembled together for transport and shipment, since in many cases, they will each be perhaps 10 feet in length.
An air intake and supply chamber 14 is supported at its front end by a collar 15 that is welded to the rear end of the pipe 6, and a combustion chamber 16 is supported at its rear end by a plate 17 that forms one end of the chamber 14. A fuel supply valve 18 having a burner tip 19 is supported by the rear end of the burner chamber and the plate 17. Fluid fuel such as liquid petroleum gas or oil atomized by pressure will be directed into the combustion chamber 16 where air for combustion will be drawn into the small perforations in the wall of the chamber 14 and through the larger perforations in the chamber 16. The flow of fuel will create a suctional force in the burner chamber, and also through all of the perforations in the wall of the chamber 14 so that there will be an impelling force moving the heated air into and through the pipes 6 and 5. The flow of air will be slow enough to permit absorption of the major portion of the heat by the two walls 5 and 6 and radiation of such heat to the area surrounding the tubes.
The sloping of the tubes 5 and 6 gives some draft effect to supplement the pressure created in the burner chamber 16, the flow from such chamber being in a stream that will enter into the rear end of the pipe 6 and also etfect entrainment of air through the perforations in the wall of chamber 14. It will be understood of course that the pipes 5 and 6 can be laid level on any convenient supports or available at the job site. It will also be understood that additional pipe sections can be added to increase the length of the heater.
I claim as my invention:
1. Heating apparatus that comprises a generally straight tube which discharges into the atmosphere at its forward end and serves as a heat radiator when interiorly heated, a tubular air-supply chamber coaxial therewith and of substantially smaller diameter than the heat radiator tube and which discharges at its forward end into the rear end of the tube and is provided with air inlet perforations distributed throughout its length, a tubular combustion chamber of short length and small diameter relative to the air-supply chamber and positioned coaxially therewith, with its rear end at the rear end of the air-supply chamber, the combustion chamber having a relatively fewer and larger diameter perforations through its wall than the air-supply chamber and discharging at its forward end into the air-supply chamber, a pressurized fluid fuel supply line, and a burner tip in the rear end of the combustion chamber supplied by said line and dis charging forwardly into this chamber, the air-supply chamber communicating directly with the atmosphere, through its perforations, and having its peripheral wall in engagement with the said tube at the forward end of the said air supply chamber.
2. Apparatus as recited in claim 1, wherein the perforations through the combustion chamber are in two axially-spaced circumferential rows, one of which is near the rear end of the combustion chamber, adjacent to the burner tip.
