In addition, the device is equipped with a cup with an opening in the bottom, closed from outside with a circle from mesh material letting through the flame force of the igniter, and flashing and igniting compositions are charged without prepressing. The cup fixes them with its bottom, and the body above the cup has two or one sealed opening of a diameter 0.4-0.7 of the inner diameter of the body, through which inside pressure is relieved, which ensures stable combustion of ignition composition. Weigh of flashing composition makes 0.4-1.2 of weight of ignition composition equal to about 1.0-1.5 g, combustion temperature of which is over 2000°C. |

Gas is heated in a heating chamber separated from a combustion chamber. The heat exchange surface of the heating chamber casing is heated by a system of small flames with the effect of surface burning on the heating chamber casing. The small flame system is formed by the interaction of the fuel flow supplied parallel to the walls of the heating chamber casing and the air flow supplied perpendicular to the walls of the heating chamber casing. Gas is heated in the heating chamber by the interaction of the system of perpendicular jets of the gas being heated, with the heat exchange surface of the heating chamber casing attacked by the system of perpendicular flames of the combustion chamber on the opposite side. |

Burner comprises concentrically set outer and inner wick pipes which are turned to the ambient space by their top flammable end faces and are communicated with each other in the lower part through channels in an insulating pipe separating them, the outer wick pipe is turned to the vessel for liquid fuel and the inner wick pipe - to the passage channel for the supplied air. The outer and inner wick pipes are made by winding of a tape made from non-flammable fabric on respectively the said insulating pipe and the inner pipe which in its lower part is connected to the air supply branch pipe and in the upper part forms the passage channel for the supplied air. The upper end face part of the inner wick pipe is made with a flat section covering the periphery part of the supplied air passage channel. |

Self-contained demontable water heating steel boiler "severny" (scdwhsb) Self-contained demontable water heating steel boiler is a set of hermetic weldments independent in the manufacture: furnace grate of the cooled structure and steel hollow panels. The said panels form the furnace volume at the four sides of the furnace grate. Three horizontal panels located above the furnace form a gas flue channel. The upper panel closes the gas flue from above and serves as a collector in circulation of the coolant. The whole structure of the boiler is connected by bolts. The cavities are connected by the circulation pipelines. |

Method to regulate parameters of gaseous fuel combustion Method to regulate parameters of a burning flare with the help of a double-wire burner, in the central and circular channels of which, equipped with coaxial nozzles, they simultaneously supply gaseous fuel, the ratio of output areas of the central and circular nozzles is maintained within the limits of 1.5…2.5, at least half of the total fuel flow is supplied via the circular nozzle, and the angle of burner inclination along the vertical line down from the longitudinal axis of the furnace is changed within 2 - 12° as fuel flow rises via a central nozzle. Fuel flight out along the circumference of the circular nozzle is done in separate jets that alternate with sections closed for fuel exit. |

Safety device for furnace gas analysis Safety device for furnace gas analysis for a gas- or oil-burning plant with electrical connection and a combustion flue for furnace gas contains an element for hazardous gas detection that can be located in the combustion flue to monitor furnace gas content and a controller for automatic regulation of air and gas ratio in furnace gas based on a signal from the detector of hazardous gas. The controller functions include power supply cut-off to the gas- or oil-burning plant when air and gas ratio in furnace gas cannot be regulated to achieve a safe parameter. The element for hazardous gas detection contains preferably a cordless sensor and the controller should contain a cordless receiver so that wireless communication could be arranged between the element for hazardous gas detection and the controller. The gas- or oil-burning plant containing the above device and the method for its manufacture are also suggested. |
