Operation and maintenance.
Short-term joint combustion of gas and fuel oil during the transition from one type of fuel to another is allowed.
Burners GM-7.0 are produced with the right direction of air rotation (if necessary, it is possible to manufacture a burner with the left direction of air rotation).
Right is the direction of air rotation clockwise, if you look at the burner from the front of the boiler, left - counterclockwise.
Burners GM-7.0 according to the method of organizing the aerodynamics of the torch are vortex burners, according to the number of air flows - to single-flow burners.
The main elements of the GM-7.0 burner are: a steam-mechanical nozzle, a gas part, a bladed air swirler, and a support.
Atomization of liquid fuel in the burner is carried out by a steam-mechanical quick-detachable nozzle.
The steam-mechanical nozzle consists of a fuel barrel, a steam pipe, a fuel swirler, a steam swirler, a distribution washer, a union nut, a body, a flange, a bracket and a screw.
The fuel barrel and the steam pipe are attached to the housing, while the fuel barrel is located concentrically within the steam pipe.
Liquid fuel through the fuel fitting and steam through the steam fitting are fed into the fuel and steam channels of the flange and further into the channels of the same name in the housing. From the housing, liquid fuel enters the fuel barrel, and steam enters the annular channel between outer surface fuel barrel and the inner surface of the steam pipe.
The fuel swirler, steam swirler, distribution washer and union nut form the spray head of the injector.
In the atomizing head, which is formed by a fuel swirler, a steam swirler, a distribution washer and a union nut, liquid fuel enters the annular channel of the fuel swirler through the holes of the distribution washer and then, through tangential channels, enters the swirl chamber, acquiring translational-rotational motion. Coming out of the nozzle of the fuel swirler in the form of a film, liquid fuel breaks up into small drops, forming a spray cone.
The steam swirler has tangential channels for swirling the steam flow, a swirling chamber and an outlet.
The steam, exiting in a swirling flow near the nozzle of the fuel swirler, participates in the process of fuel atomization.
The direction of spin of fuel and steam is provided in one direction.
The direction of the swirl of fuel and steam is opposite to the swirl of air.
The working surface of the distribution washer is the surface to which the fuel swirler adjoins. The required density between the atomizing parts is achieved due to the high cleanliness of the adjacent surfaces.
To maintain the characteristics of the injector during its service life and reduce wear, the fuel swirler, steam swirler and distribution washer are made of CVG steel with subsequent heat treatment, and their flow and sealing surfaces are of high purity.
On the frontal plane of the burner there is a gas supply pipe and pipes for installing an ignition-protective device and a photo sensor.
Adjust the depth of entry of the spray head of the nozzle relative to the air swirler and orient the nozzle (change the angle) relative to the axis of the burner or furnace during commissioning allows flange mounting.
The gas part is a device consisting of a gas annular manifold with gas outlets and a supply pipe.
The ring collector in cross section has rectangular shape. A fairing is attached to the end of the gas manifold for a smooth entry of air into the air guide device (VNU). A separating shell is welded inside the gas collector, which makes it possible to evenly distribute the gas over the collector in the presence of one gas supply pipe and a relatively high gas velocity at the collector inlet.
The gas outlets in the manifold are arranged in one row. The cross section and pitch of the gas holes are calculated taking into account the optimal penetration of gas jets into the air flow.
The vane swirler of the right or left swirl of the air flow is one of the main units in the flow part of the VL burner. The swirler consists of profile blades, inner and outer shells. Profile blades make it possible to reduce (compared to straight blades) the aerodynamic drag of the HPU.
A cast-iron or steel welded support in the form of a ring with cylindrical protrusions on both sides is designed to fasten the burner to the front of the boiler.
Gas-oil burners GM-7.0 are designed for separate combustion of natural gas and fuel oil and are used with steam gas-oil boilers of the DE-GM type, as well as with hot water boilers developed on the basis of DE-GM steam boilers.

GM gas-oil burners, which are currently manufactured by the TeploEnergoSnab Boiler Equipment Plant under the TES trademark, were specially designed for installation on steam boilers DE (E) of the corresponding thermal power. The burners are produced in several standard sizes from 2.5 MW to 10 MW. In addition to GM, the GMP-16 burner is produced, which has the same design as the GM burner devices. The power of GMP-16 is 18 MW. The “P” index, which is in the name of the GMP-16, means that the burner has a right-hand flame swirl by default. AT recent times, at the request of customers, began to produce GMP-16 and left rotation, they are called "GMP-16 left". The remaining burners of this series GM-2.5, GM-4.5, GM-7 and GM-10 are produced both in left-hand and right-hand rotation.
GM and GMP-16, being combined burners, operate both on natural gas and on fuel oil. In normal operating modes, they must operate either on one or the other type of fuel. However, the manufacturer allows short-term combustion of both fuel oil and gas at the same time at the time of switching from one type of fuel to another.
To use fuel oil as a fuel on GM and GMP-16, the burners must be equipped with FPM steam-mechanical nozzles. When operating on liquid fuel, steam must be supplied to the burner. The obligatory presence of steam is explained by the fact that with its help there is a normal dispersion of fuel oil and, accordingly, complete combustion liquid fuel. The required liquid fuel pressure must be provided by the fuel oil preparation system. All FPM injectors are equipped with a spare parts kit.
Being engaged in readjustment of the boiler, trying to increase or decrease the power and productivity, some customers resort to replacing the spare parts and accessories of the burner. In this case, the diameter of the fuel swirler should change. This method not prescribed in the instruction manual from the manufacturer, but nevertheless showed its performance. The decision to replace the SPTA is made only by the customer.
Air is supplied for operation from a separate fan. The size and type of fan is supported for each boiler separately.
Despite the fact that this equipment was developed for specific DE boilers, it can also be installed on another technological equipment where a burner is required. But this is only possible if steam is provided at the facility. Oil-gas burners of this series do not have their own air box, since such a box is part of the DE boilers for which these burners are designed. Taking this into account, in addition to steam, an air box will have to be made at the facility.
For this equipment, at the request of the customer, our company can supply all the necessary equipment, such as a fan, a smoke exhauster, an ignition burner and an EZZU, a burner automation system and a gas line.
