The invention relates to the technical field of thickened oil development, and discloses a method of viscosity reduction and cold production of a shallow oil reservoir. The method is carried out by the first step, firstly confirming that the oil reservoir has the following characteristics: the ground crude oil viscosity is 50 mPa.s-20000 Mpa.s when the temperature is 20 DEG C, the acid value of the thickened oil is 0.6 mgKOH / g-2.3 mgKOH / g, the reservoir thickness is more than 5 m; the bury depth of the heavy oil reservoir is less than 800 m, the reservoir porosity is more than 15%; the permeability is more than 50x10<-3> mu m2; the reservoir is a reverse rhythmic stratum. Compared with the steam driving method, the development cost of the shallow oil reservoir by the method is reduced by 28-36%; for the shallow oil reservoir is developed without using the steam driving and other methods, the problems of steam channeling at post period of development, serious 'over-coating' phenomenon, and low gas injection utilization efficiency at post period are also not existed; meanwhile, high-temperature steam is also not produced without fuel gas; therefore, boiler explosion, high-temperature scalding and other safety accidents cannot be happened; greenhouse gases are not generated; compared with the steam driving development, the output is further improved.

The present invention relates to the ignition and pressure lifting method for medium temperature and medium pressure gas burning boiler with coke oven gas as fuel. During ignition, lifting pressure and normal operation, hot blast baffle opening, blower baffle opening, induced draft fan baffle opening, gas regulating door opening and negative hearth pressure in the boiler are set and regulated, so as to control the inflammable gas density inside the boiler during ignition and lifting pressure below the explosion limit and to avoid boiler explosion accident. The ignition and pressure lifting method of the present invention is suitable for all types of gas burning boilers with PLC program controlled ignition system.

The invention discloses a system and method for preventing a boiler from exploding outside. The system comprises a hearth, a water seal plug board, a slag conveyor and a water drainage system. The lower end of the hearth is fixedly provided with the water seal plug board. The slag conveyor is arranged at the lower end of the water seal plug board. The water drainage system is arranged on the slag conveyor and comprises a water drainage valve, a control valve and a pressure detection device. A pressure monitoring device is arranged on the hearth and used for detecting the pressure inside the hearth of the boiler and transmitting a detection signal to the control valve. The control valve is connected with a water drainage switch. The water drainage switch is arranged in a water tank of the slag conveyor. By means of the system and method, when the difference value of the pressure inside the hearth and the environment pressure reaches the preset value, a pressure switch of the system acts, the water drainage switch is opened automatically, the water surface goes down, the space in the hearth is communicated with the atmospheric environment outside the hearth, the pressure balance is reached, and the hearth is protected effectively.

The invention relates to a boiler safety explosion-proof device and effectively solves the problem that after an existing boiler explosion-proof device exists, the existing boiler explosion-proof device is not complete in explosion-proof function. According to the technical scheme, the boiler safety explosion-proof device comprises a furnace body; a hollow disk is arranged above the furnace body; a rotating shaft is installed in the center of the hollow disk, and is evenly provided with a plurality of fan blades; a first pipeline is arranged on the right side of the hollow disk, and is internally provided with a first slider; the first slider is connected with the upper end of the first pipeline through a first pressure spring; the hollow disk is communicated with a cavity of the first pipeline through a steam pipeline; a water tank is arranged above the hollow disk which is communicated with the water tank; the lower end of the water tank is communicated with a furnace body 1 through a water draining pipe which is provided with a check valve; the rotating shaft is provided with a rotating disk in which a plurality of blind holes are formed; second sliders are formed in the blind holes, and are connected with the blind holes through tension springs; an oil conveying pipeline is arranged on the rear side of the rotating disk; and an oil control device is arranged between the rotating disk and the oil conveying pipeline. The boiler safety explosion-proof device is more convenient, fast and humanized.

The invention provides a dual purpose energy-saving boiler for hot water and steam. The boiler comprises an upper water liner, a lower water liner, a main liner body, a subsidiary water tank, a combustion chamber and an electric heating tube, wherein the main liner body comprises an inner circle of a water pipe and an outer circle of a water pipe, and is a pipeline structure, thereby not only increasing the heating area in the main liner body, improving the heat utilization rate of heat energy, but also having strong pressure resistance, preventing occurrence of boiler explosion, and ensuringthe safety of the boiler; after the subsidiary water tank heats cold water by residual heat, the water enters the lower water liner, the main liner body and the upper water liner, thereby improving the efficiency of heat energy, and saving energy. The boiler can select different heat modes conveniently according the requirement of different production situations, selects different single fuels ormixture fuels or electric heating, such as coal, firewood, electricity, fuel, gas and the like. The boiler can be used both as a steam boiler and a hot water boiler, is the energy-saving environment-friendly boiler with steam and hot water dual purposes.

The invention is applicable to the technical field of explosion-proof equipment, and provides an explosion-proof device for a bursting membrane boiler, which includes a device box, which is fixedly installed on the furnace body, and also includes: a drive assembly, which is installed on the device In the box; a flame retardant assembly, the flame retardant assembly is installed in the fuel pipe; and a dispersal assembly, the dispersal assembly includes a first rotating part, a dispersing part, a support, a first movable part, a second movable part, a first connection piece, the second connecting piece, the third connecting piece and the fixing frame. The bursting membrane boiler explosion-proof device in the present invention can quickly disperse the steam through the flame-retardant component and the dispersing component, and can also block the fuel and block the steam from regenerating, which improves the working efficiency and efficiency of the explosion-proof device. practicality.
