Method for heating of boiler house

FIELD: heat engineering, designed for rational heating of boiler house rooms for heat supply of industrial enterprises and residential districts.

SUBSTANCE: the method consists in bleeding of air outside the boiler house room. The boiler room with the id of a partition is divided into two isolated compartments. Mounted in the first compartment is the equipment giving off toxic solid and gaseous substances during operation thus contaminating the atmosphere (for example, boilers with burners), and installed in the second compartment is the equipment liberating heat during operation without liberation of harmful substances (heat exchangers, water heaters, etc.). The equipment of the second compartment liberates heat during operation that is accumulated under the building roof. This warm and clean air with the aid of ventilation plants is supplied through pipe-lines to the lower zone of both compartments located at the zero level. There is no need in use is made of already available resource.

EFFECT: reduced consumption of electric power for producing optimum temperature in the boiler house.

The method of heating boiler relates to the field of engineering and is designed for efficient heating boiler for heating of industrial enterprises and residential areas.

Space heating boiler is carried out in accordance with the instructions of SNIP II-35-76 (second Part. Design standards. Chapter 35. Boiler installation. Moscow, Stroyizdat, 1977).

One of the requirements of SNIP is the rational layout of the boiler equipment and requirements to ensure safety for staff.

In particular, in the boiler house must be maintained at the optimal temperature for the normalization of work of the staff. For these purposes, the projects boilers provided by the installation of heating equipment (Shchekin. "Heating and ventilation", Budivelnik Kiev, 1976). The need for heating boilers due to the fact that when operating the ventilation in the boiler room are air flows, which are at different levels from the ground level have a different temperature. For example, blower fans used in burners, boilers, when their work create streams of cold air in the lower layers of the premises. This thread blows legs of the staff, at the same time, the upper body of the operator is heated th is m, allocated boilers. This temperature difference leads to occupational diseases. In order to create a uniform temperature at various levels in buildings boiler house provided by the installation of heaters, which take outside air, heat it up and serve in the lower layers of the premises.

The disadvantage of this method of temperature compensation is the high consumption of electricity.

The technical result of the invention is to reduce the energy consumption required for heating the boiler.

The technical result is achieved in that the method comprises the selection of air out of the boiler room, the filtration and flow into the inner space of the boiler.

The boiler room by the partition is divided into two isolated from each compartment. In the first compartment mounted equipment, emitting its operation of polluting the atmosphere with toxic solid and gaseous substances (e.g., boilers with burners), and the second compartment of equipment, emitting only heat that accumulates under the roof of the building. This warmed naturally air by using ventilation systems by the tubes at the bottom, located on the ground level area of both compartments.

Distribution diagram of convection currents is shown in che is the same.

Building 1 of the boiler is divided into two compartments by a partition 2. In the first compartment oven with 3 burners and the blower fans 4. The building is equipped with exhaust ventilation 5. In the second compartment of the exchanger and the heater 6. Under the roof mounted air handling unit 7, the feed in line 8, the warm air in the lower layers of both compartments. This eliminates the need to use special heaters, i.e. space heating uses existing resource. Be used for the same purpose, the warm air accumulated under the roof of the first compartment, not because of its toxicity.

The method of heating the boiler, including the selection of air out of the boiler room, the filtration and flow into the inner space of the boiler, characterized in that the interior of the boiler is divided by a partition into two isolated from each compartment, the first of which is set equipment emitting operation of polluting the atmosphere with toxic solid and gaseous substances, and in the second compartment of equipment, emitting only heat without releasing hazardous emissions and air for heating the boiler is taken from the most heated areas of the second compartment located under the roof, and using ventilation systems for pipelines is udaetsya at the bottom, located on the ground level area of both compartments.
