Mobile water heating apparatus

摘要

Mobile water heating systems for producing hot water are disclosed herein. In one embodiment, a mobile water heating system includes a water heater having an oval-cylindrical shape. The water heater includes a shell, a lid and a water reservoir having a screen. A first heating coil and a second heating coil can extend between the screen and a first cone and a second cone, respectively. A first burner and a second burner can be configured to mix and combust fuel and air and direct the resulting flames through the heating coils. Pall rings can at least partially fill an interior volume of the water heater and the combustion of the fuel and air can heat the heating coils and the pall rings. Water can be heated by being directed through the heating coils and through a water manifold positioned to spray water on the pall rings.

主权项

1. A water heating system comprising:
a water heater, the water heater comprising
a shell defining an internal volume and having an oval shape;a manifold having a plurality of nozzles positioned to spray a first portion of water within the internal volume;a first heating coil positioned at least partially within the internal volume and having a first tube coiled in the shape of a first cylinder, wherein the first tube includes a first water inlet and a first water outlet, and wherein the first water inlet is positioned to receive a second portion of water that flows through the first tube to the first water outlet;a second heating coil positioned at least partially within the internal volume and having a second tube coiled in the shape of a second cylinder, wherein the first heating coil and the second heating coil extend generally parallel and side by side in relation to one another, wherein the second tube includes a second water inlet and a second water outlet, wherein the second water inlet is positioned to receive a third portion of water that flows through the second tube to the second water outlet, and wherein the plurality of nozzles are positioned to spray the first portion of water external to the first heating coil and external to the second heating coil;a first burner positioned to direct flames into the first cylinder to heat the second portion of water via contact of the flames with the first heating coil;a second burner positioned to direct flames into the second cylinder to heat the third portion of water via contact of the flames with the second heating coil;a first vaporization coil having a first fuel inlet for receiving a first portion of fuel and a first fuel outlet for providing the first portion of fuel to the first burner, wherein the first vaporization coil is positioned to receive heat via the flames from the first burner and transform at least a portion of the first portion of fuel from a liquid state to a gaseous state; anda second vaporization coil having a second fuel inlet for receiving a second portion of fuel and a second fuel outlet for providing the second portion of fuel to the second burner, wherein the second vaporization coil is positioned to receive heat via the flames from the second burner and transform at least a portion of the second portion of fuel from a liquid state to a gaseous state.
