RU27684U1 - WATER BOILER - Google Patents

Description

The utility model relates to the field of heating and hot water supply and is designed to generate heat for household, industrial and agricultural purposes.

Known hot water boiler (hereinafter referred to as the boiler), 1 used for heating and hot water supply of household and industrial premises with an area of 2000 + 3000 square meters, including a heat exchanger (electrodes), a furnace (case), a set of automation equipment.

The disadvantage of this boiler is the low efficiency of the process of converting fuel (in particular gas) into thermal energy, due to the fact that it uses electricity (electric boiler) as fuel. Therefore, the use of this boiler is justified only in regions where there are no other more economical types of fuel, including waste wood.

In regions where there are gas pipelines, especially woodworking waste, the use of this boiler leads to significant costs associated with burning gas to generate thermal energy in steam boilers of a thermal power plant, which generates electricity, by converting it into thermal energy in a known boiler.

Known hot water boiler 2, used for heating and hot water supply of domestic and industrial premises with an area of 2000 + 3000 square meters, including a heat exchanger, firebox Ball pipe, a set of automation equipment.

The disadvantage of this boiler is the high cost of extracting and transporting fuel to the consumer, due to the fact that it uses a firebox that uses gas as fuel. The use of this boiler is possible only in regions where there is a gas pipeline.

The purpose of the utility model is to reduce costs in the generation of heat, utilize woodworking waste and expand the distribution zone of the boiler.

This goal is achieved by the fact that in a boiler that includes a heat exchanger, a furnace, a heat pipe, a set of automation equipment, a furnace is used that uses woodworking waste as boiler fuel.

Figure 1 shows a diagram of the implementation of a utility model.

According to the figure, the heat carrier is prepared in the heat exchanger 1 mounted on the frame 2. The fuel is burned and gas is generated in the furnace (3), which has a figured lining, and the generated and pyrolysis gases are burned in a fugged flame tube (4). Fuel is loaded into the hole located at the top of the hopper (5) and ignited through an open door (6) located on the furnace body (3). Accumulated ash during the operation of the boiler is removed from the ash pan (7) through the open primary air door (8) and the doors (9) and (10) located on the flame tube body (4). The coolant is heated in three circuits (11), (12), (13) of the heat exchanger and the circuit (14) of the cooling cover (15).

Heat generation is as follows:

Woodworking waste - chips, chips, cuttings, sawdust, as well as their combination, loaded into the hopper (5) under the influence of gravity and gradually burn down as it burns, passing through the zones of drying, pyrolysis of gasification and combustion. In this case, the furnace chamber is under discharge.

The air entering through the primary air door (8) into the ash pan (7) is mixed with water vapor. The vapor-air mixture through the grate (18) sequentially passes through the combustion and gasification zones. A small amount of air additionally flows through the leaks of the fuel layer and the connection of the hopper (5) with the furnace body (3).

The resulting generated and perolysis gases from the steam-air mixture and wood elements are collected under the smallest diameter ring of the furnace lining and, under the action of vacuum, rush into the flame tube (4).

In the flame tube (4), the gases are mixed with the secondary air entering through the secondary air hole (19) and burned in the form of a torch inside the Gift tube and the primary circuit (11) of the heat exchanger (1). Flue gases, having partially lost their thermal energy in the first circuit (11), go around the water-cooling cover (15) and enter the space between the first (11) and (13) circuits. Going down, flue gases wash the rarefied second circuit (12). The cooled flue gases are removed through the annular duct (20) into the chimney (21).

The coolant (water) is supplied to the boiler through a pipeline (22) passes through the circuits (11), (12), (13), (14) and through the pipelines of the outlet of the hot coolant (23) enters the consumer. An explosive valve (24) is installed on the boiler cover (15) to prevent an increase in pressure in the furnace. The combustion in the furnace is monitored through a peep (25).

When using an electric boiler with a capacity of 200 kW, the cost of electric energy is 200 kW / h at a price of 0.33 rubles. for 1 kW / h, the cost of heating this building will amount to 792 rubles. per day.

When using gas for a boiler with a capacity of 200 kW, gas costs will be 240 nm3 per day. At a price of 1nm3 of gas 0.65 rubles, the cost of heating this building will be 130 rubles. per day.

When used for a 200 kW boiler as fuel, woodworking waste, which is a burden for the woodworking industry, the cost of heating this building will be “О

The economic effect of using the declared boiler for a heating season in this region of 8 months will amount to 760320 rubles with electric heating and 74,880 rubles. with gas fuel.
