Abstract

Invention m. used in boiler rooms with an open hot water circuit. The purpose of the invention is to improve the quality of deaeration and heat transfer. In the process of fuel combustion in the furnace 5, the heat released in the boiler tubes 17, the outer walls 8 of the deaerator 4, and the water in the contact chamber 1 are heated up. Part of the sprayed water falls on the outer surface of the upper walls 7 of the deaerator 4, from where it is discharged and the tray 3. From the tray 3, the heated water is supplied to the distributor 10 and sprayed onto the walls 8, while a boiling film is formed on the surface of the walls 8, which deactivates gases in it. The deaerated water accumulates in the collection trays 11, from where it is discharged through pipe 12 to the boiler feed system. Most of the steam condenses on the upper walls 7 of deaerator 4 and enters the tray 3. The deaerated gases are removed through pipe 16. The design of the water heater makes it possible to use the radiant heat of the furnace 5 to maintain the end temperature in deaerator 4, to reduce heat loss to the environment, as well as improve the quality of deaeration. 1 il.

Description

The invention relates to a power system and can be used in boiler rooms with an open scheme of hot water supply.

The aim of the invention is to improve the quality of deaeration and heat transfer.

The drawing shows a water heater; atelier.

The water heater contains located above each other, respectively, a contact chamber 1 with a water distribution manifold 2 and a sub-compartment 3, a deaerator 4 and a furnace 5, so 10 n

Day 1 with a contact chamber of 1 ha31 οι and

P1;

l · with B | the upper wall of the furnace 5, Cie and the lower walls 7 and 8 of the deaerator 4 are installed with an inclination to the periphery.

The deaerator 4 is also equipped with a pipe 12 for discharging deaerated water, connected to the collection trays 11, and its water distributor 10 is connected to the pallet 3 of the contact chamber 1,

The walls 7-9 of the deaerator are tightly interconnected with the formation of a closed cavity. The upper walls 7 below are adjacent to the condensate and water collectors 13 and 14, and a pipe 16 of deaerated gases is installed in the outlet section 15 of the gas duct 6. In the furnace 5, boiler pipes 17 are located. 40 bypass 6, covering the deaerator 4, flanked by the upper, lower and side walls 7-9 and equipped with a water distributor 10 with inclined foxes, adjacent to the bottom of the collection chambers 11 and formed by the lower tenks 8, made at the same time top15

The water heater operates as follows.

The heat generated during the combustion of fuel in the furnace 5, heats the coolant in the boiler pipes 17, and 45 Also, the lower walls 9 of the deaerator 4.

Then the flue gases through the gas duct 6 enter the contact chamber 1, where they encounter an oncoming drip flow of water supplied through the water distribution manifold 2, they give off heat and are discharged into the atmosphere through the outlet section 15 of the gas duct 6. Part of the sprayed water falls on the outer surface of the upper walls of 7 55 Deaerator 4, from where it merges into

BHiBSIH Order 6951/38 collectors 14 of water, and then into pan 3, from where water heated to 70-80 ° C is supplied to the water distributor 10 of the deaerator 4 and sprayed onto the walls 8, while a thin boiling film is formed on the surface of the walls 8, actively deaerating the dissolved there are gases in it. Deaerated water is collected in prefabricated trays 11, from where it is discharged through the pipe 12 to the boiler feed system (not shown).

Most of the steam also condenses on the upper walls 7 of the deaerator 4, while the gas partially dissolves in the condensate. The condenser from the condensate collector 13 enters the pan 3. Deaerated gases are removed through the pipe 16.

I

The design of the water heater allows the use of radiant heat from the furnace 5 to maintain the saturation temperature in the deaerator 4, reduce heat loss to the environment, and also improve the quality of deaeration.

Claims (1)
