Biomass boilers need green new energy. Compared with other boilers, biomass boilers have the following four major advantages: one boiler is multi-purpose, and can cook, boil water, and bathe while heating. Strong conversion system, low starting heat transfer temperature and fast heat transfer speed. Xinxiang Gas steam generator Low installation cost, safe heating: the equipment is universal, without changing the original heating equipment, and the pipes and radiators are universal. Water circulation is used to achieve a wide range of heating materials, which will never be exhausted. It can be taken everywhere (such as rice husks, corn stalks, rice stalks, wheat). Safety and environmental protection: low working pressure, cooking, water boiling, bathing, heating, etc., and it is also suitable for burning boilers, greenhouse heating Large area heating and small and medium-sized hotels can be used all year round without seasonal restrictions. small-scale Gas steam generator how much The reason why the ignition of biomass boiler is difficult is that the stable small fire signal cannot be established, which is caused by the failure of the small fire detector to detect the fire normally. The flame detector for small fire is ionization type flame detector, which requires a contact area with the flame, stable flame size, and gas pressure controlled within a strict range.
The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Xinxiang Gas steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. small-scale Gas steam generator how much Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.
The existing industrial boiler flue gas waste heat recovery equipment mainly includes tubular heat exchanger and full heat pipe heat exchanger. Tube and tube heat exchanger can be composed of finned tube bundles. The advantage of finned tube is that it can withstand higher temperature, but has low heat transfer coefficient and large floor area. Xinxiang Gas steam generator The flue gas of industrial boilers contains sulfur and other acidic substances. In the low temperature zone (flue gas outlet section), the temperature may be lower than the dew point of the acidic substances. The acidic substances will dew on the pipe wall, corrode the shell of the fin tube. The fin tube heat exchanger has poor operating reliability and low service life. small-scale Gas steam generator how much The total heat pipe heat exchanger of boiler flue gas waste heat recovery equipment is composed of heat pipe bundles. Its shell is made of multi-layer composite materials. The heat pipe structure is complex, the cost is relatively expensive, the service life is short, and the steel consumption is large. It is difficult for users to accept it, and it is difficult to promote its application in production. The composite heat pipe heater not only takes into account the heat exchange effect, but also takes into account the economic affordability of the investors in production, which is particularly suitable for the current situation in China's industrial production.
The waste heat boiler has advantages in the subdivided industry and is the leading enterprise in the industry. The company's main products are various types of waste heat boilers, industrial boilers, power station boilers, nuclear power equipment and power station auxiliaries. It is a research, development, design and manufacturing base for waste heat boilers with large scale and complete varieties in China. Xinxiang Gas steam generator Waste heat boiler is a typical energy-saving and emission reduction equipment. Its heat source can come from high-temperature flue gas waste heat, chemical reaction waste heat, combustible waste gas waste heat, and even can use high-temperature product waste heat. At present, the company has more than 20 series and more than 100 varieties of waste heat boiler products, which are widely used in steel, building materials, power, nonferrous metals, coking, chemical and other industries. small-scale Gas steam generator how much In 2008, the company produced 272 sets of waste heat boilers of various types, with a total of 10268 steam tons, accounting for 34% of the comprehensive market share based on steam tons; According to the output value, the market share is 47%, ranking first in the waste heat boiler industry.
