A boiler according to the invention contains an additional air channel (9) with an inbuilt fan (10) with adjustable output. The first end (91) of the additional air channel (9) is connected with the under-stoker space (11) located outside of the wind boxes (5) of the under-stoker wind boxes system (4). The other end (9') of the additional air channel (9) is connected with either the space of the channel (6) supplying outside air to the wind boxes (5) or with the atmosphere or with the secondary air channel of the combustion chamber (2). Modernization of the existing boilers consists in installation in the described above method of an additional air channel (9) with an inbuilt fan (10). The method of elimination of uncontrolled leakages in a stoker-fired boiler consist in leading out and air, getting through air gaps, from the under-stoker space of the boiler located outside of the wind boxes (5) to the described above additional air channel (6), wherein current output of the fan (10) built into this channel is proportional to the current difference between temperature of air supplied to the wind boxes (5) and temperature of air in the additional air channel (6).

The invention discloses a preparing technology for an anti-ageing elevator compensation cable. The preparing technology comprises the following steps that firstly, a plurality of aviation steel wire ropes or compensation chains are plated with zinc, wherein the surfaces of the aviation steel wire ropes or compensation chains are plated with the super-thick zinc layers at 265-290 g / m<2>; secondly, winding is carried out, wherein the aviation steel wire ropes obtained in the first step are wound into a steel wire rope core through a winding machine, and the steel wire rope core is put into an anti-rusting oil trough to be soaked for 15-35 min; thirdly, a corrosion-resistant rubber sheath is arranged in a sleeving mode; fourthly, a PP protection layer is smeared, wherein a PP material is smeared to the outer part of the corrosion-resistant rubber sheath with the plastic coating technology, the PP protection layer with the thickness of 0.3-1.5 mm is formed, and supra polymer polyvinyl chloride with the weight percentage of 18-23% is added into the PP material in the plastic coating technology. The corrosion resistance and the anti-ageing property of the compensation cable prepared through the technology are improved, the stable performance of the product is maintained in the harsh environment with strong ultraviolet while various physical indexes in the conventional environment are ensured, the service life is prolonged, and the safety is improved.

The present invention provides an inertial / satellite integrated navigation demonstration verification system for data reproduction. The inertial / satellite integrated navigation demonstration verification system comprises: a data transmitting and receiving module for reading IMU data and GPS data, outputting an analog second pulse, and then transmitting the IMU data and the GPS data to a navigation computer module; the navigation computer module for receiving the IMU data and the GPS data transmitted by the data transmitting and receiving module, caching, and performing data processing by using a master-slave DSP working mode; and a data displaying module for displaying the data processed by the navigation computer module, dynamically reproducing the movement state in an offline manner, and evaluating the precision of a new navigation demonstration verification algorithm. With the inertial / satellite integrated navigation demonstration verification system of the present invention, the real IMU and GPS receivers are replaced with the data transmitting and receiving module so as to the reduce the physical loss of the system and improve the service life, and the system movement state is dynamically reproduced in the offline manner so as to demonstrate and verify the new navigation algorithm.

The invention relates to an energy-gathering gas-saving infrared generator for gas appliances. The energy-gathering gas-saving infrared generator comprises a long metal strip divided into a wave strip and a flat strip, the wave strip and the flat strip are interlapped and then coiled or parallelly stacked to form the infrared generator, and a gas passing pipeline is formed between convex embossed stripes on the surface of the wave strip and a plane of the flat strip. Through structural change of the wave strip, the wave strip can be of a wavy structure or bent structure, complexity of manufacture and assembly technology is lowered, materials are saved, unstable factors during manufacture and use are decreased, and safety performance of products is greatly improved.
