Domestic boiler-battery


(57) Abstract:

Usage: in the heat. The essence of the invention: reduction of air pollution and heat loss is provided by the fact that the boiler-the battery contains a water chamber 1, the combustion device 2, a steam tube 3 and the heating pipe 4 with fins. The new device is a fin made in the form of perforated disks 6 with decreasing the furnace 2 diameters in a closed tube 5, partially filled with water and mounted in the heating pipe 4. 1 Il.

The invention relates to energy, and in particular to equipment for heating of domestic and industrial premises.

Known furnace, consisting of a water tank, furnace grate, gas channels and hot-water shells [1]

The disadvantage of this furnace is a significant heat loss due to high temperature exhaust gases.

Known boiler containing water chamber (tank) with a combustion device and a flame tube within which is located a heating pipe with fins, providing less heat loss. [2]

The disadvantage of this boiler is a significant heat loss and air pollution due to the low efficiency is and the expense of low turbulence of the gas stream, and incomplete combustion.

The technical effect of the invention is the reduction of air pollution and heat losses due to the intensification of heat exchange.

This goal is achieved by the fact that in the proposed device, containing a water chamber with a combustion device and a flame tube within which is located a water pipe with fins. In accordance with the invention, the fins are placed in the zone of maximum temperature, made of perforated disks with decreasing the furnace diameters in a closed tube, partially filled with water and mounted in the heating pipe.

Figure 1 schematically shows a longitudinal section of the proposed boiler accumulator, which contains a water chamber 1, the combustion device 2, the heating pipe 3, a water pipe 4, the heat pipe 5, the perforated disks 6.

The proposed boiler operates as follows: when the burning of fuel (wood, coal, gas and so on) in the furnace 2 is heated perforated disk 6, which are located in the zone of maximum temperature of the flame tube 3. Drives transferring heat to the water in the heat pipe 5, which evaporates and condenses in the upper part, where the tube is in contact with the cold water which Yes can be used by the consumer. Gave heat gases through the heating pipe 3, go outside, giving additional heat to the heating pipe and the walls of the water chamber.

The disks that are in the zone of maximum temperature, heated and promote more complete combustion in between particles of soot, tar, gases, performing a catalytic function. Because of their perforation intense heat turboservice gas streams. Increasing from the furnace diameter perforated disks also contributes turbulence in the gas flow and uniform heat transfer from the flame to heat the pipe. The evaporation and condensation of water circulating in the heat pipe is the most efficient heat exchanger. In the complete combustion of the fuel and the catalytic combustion of the particles between the perforated discs escaping gases have a relatively low temperature and to a lesser extent pollute the atmosphere.

Thus, welded to the heat pipe heat pipe with fins perforated disks, decreasing to the furnace diameter allows intensificate heat transfer and to reduce air pollution and heat loss on hot water.

These features soustendue, because they enable the creation of a positive effect, reflected in the chain of supply and there are no known technical solutions.

The proposed boiler manufactured and tested. The temperature of the effluent gases with the intensification of the combustion of wood blocks does not exceed 50oC, with sparks and soot is not observed.

Simple design, low inertia, fire safety and environmental friendliness allows you to use the proposed boiler for domestic, agricultural, industrial and other purposes.

Domestic boiler-battery, consisting of a water chamber, furnaces, flame tube, inside which is located a heating tube with fins, wherein the fins are made perforated discs with decreasing diameters to the furnace in a closed tube, partially filled with water and mounted in the heating pipe.
