When to close the damper in the furnace: what will happen if you do not close the damper in time.

The damper is a constructive part of any furnace. Its role is to control the draft in the chimney - while the stove is already flooded, as well as at the end of the furnace. In complex furnace mechanisms (multi-channel), the valve is used to switch the smoke passages. The valve solves its main task due to the movement in the grooves of the frame. In the process of this there is a change in the area of the smoke channel, respectively, this leads to a decrease or increase in vacuum. There are several flapper options. The first is a frame inside which a sheet of metal moves. For its manufacture, sheet metal is used. There are round designs, they are called views. To close it, either a round cover or a washer is used. Views are made of cast iron.

Each valve has certain advantages and disadvantages. But, in particular, soot is deposited on each of them, and therefore they must be handled carefully, otherwise it may get dirty. It is installed in a pipe through which hot air is vented. There is also a variant of the shutter, in which a rotating shutter is used. It is also installed in the chimney, and by rotating the valve you can adjust the movement of hot air.

When to close the oven door

To maintain heat in the house and adjust traction, it is necessary to close the shutter. As a rule, it is located at the beginning of the chimney and if it remains open, the stove will quickly lose heat.

An open gate valve provides internal ventilation in the furnace - this is as follows: the street air enters the furnace through the blower and, after heating through the chimney, goes to the street. When the damper is open and the furnace ceases, the heated bricks will quickly cool down.

If it is closed, then the cooling of the furnace is slower, this is also because the hot air held in it warms up the brick walls of the furnace more, in this state the Russian stove is able to retain heat for up to two days.

In other words, the valve allows you to increase the efficiency of using the furnace structure installed in the house.

REFERENCE! According to fire safety standards, it is unacceptable to completely block the chimney. Using a gate, it is permissible to overlap 85% of the cross section.

Why close the shutter

As a rule, the owner of the furnace knows its features and understands when it is time to close or open the damper. If you do not close the shutter in time, the following will happen: either the stove cools down quickly, or the fuel burns out too quickly, not having time how to warm up the structure. However, there is the following danger: when the shutter is closed, carbon monoxide will accumulate and, as a result, poisoning others.

REFERENCE! Carbon monoxide is a toxic substance. You can list the main signs of poisoning, if a person is poisoned with carbon monoxide, then he will begin to feel dizzy, hearing will decrease, and his vision will deteriorate. It will become difficult for him to breathe, and the appearance of a severe headache can be added to this. The victim must immediately call an ambulance.

What will happen if you do not close the shutter in time

As already noted, the valve is designed primarily to control the movement of the gas flow. This process allows you to ensure the safety of heat that is generated due to the combustion of firewood. In addition, through the damper ventilation of the furnace.

A valve not closed in time can lead to the following consequences:

Fast heat dissipation.
Rapid combustion of fuel, which leads to additional costs for the purchase of new firewood or coal.
The accumulation of carbon monoxide in the room, which in certain concentrations can lead to poisoning of residents.

In addition, an unclosed shutter in time can lead to a violation of the thermal regime of the heating devices, or, more simply, to overheating of the walls, which is completely unacceptable - the maximum temperature of the furnace walls should not exceed 70 degrees.

That is, the valve is a rather simple design that ensures the efficiency of traditional stove heating. In the chimney of modern furnace equipment, the presence of such a device is simply necessary.
