the structural design of a fire tube boiler

Maintenance and repair of steam the structural design of a fire tube boiler method every customer wants to buy a durable good steam boiler Di, we provide the best quality Di boiler manufacturers are on the one hand, on the other hand the needs of each user can carefully Di maintenance and maintenance of boilers, improve the life of the boiler to make steam, Di to bring you more value in return! So, how to care and maintain it, the editor based on years of experience, special summarized as follows: First, the first maintenance, water supply must be a qualified treatment, water temperature should fight with the furnace temperature close to, preferably above 20 ℃. Secondly, the need for regular low water cutoff apparatus for inspection, cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; but also for the sewage operation, at least once a day, after the sewage drain valve should be checked because of possible contamination and leaks; if it must be excluded. When there is no shutdown and the steam pressure, the steam space of the boiler and air entrapment generates a negative pressure, should rise again to the fire burning total steam valve is opened. Meanwhile, when the smoke tube fouling, so that the exhaust gas temperature will increase, thereby reducing the efficiency of the boiler, the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling. Second, anti-corrosion First, after the shutdown, the pot to prevent corrosion, maintenance needs as soon as possible. If the short-term care, then, can be used wet regimen; i.e. after the shutdown, the water fill the furnace, the air discharge all. If the long-term maintenance, then the maintenance of law can be dry, that water off the furnace after shutdown, open the lower hand hole, dry water pot, and through the lower hand hole, put a drying agent, and should be changed regularly , can start a monthly check and replace; times can later be three months. It should be noted, before the boiler is enabled, be sure to remove all desiccant. Third, the first maintenance, boiler operation, every one hour to conduct an inspection apparatus, the focus operation member and the rotary boiler safety checking apparatus. Secondly, inspection, testing and regular operation of the project cycle, make specific provisions and loading site as an icon. Again, operating personnel records based on timely completion of the inspection. Finally, the site must be kept clean, so that no debris, no fouling, no water, no grease.

The Fangkuai Group's unique full-operating the structural design of a fire tube boiler operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.

Electricity and steam are almost required in every step of raw sugar process, especially in juice extraction, clarification, evaporation and sugar drying, good quality steam takes a crucial role. Thus selection of steam the structural design of a fire tube boilers becomes very important for sugar plant.

15 tph SZL series chain grate steam the structural design of a fire tube boilers for the edible oil industry

Saturated steam is mainly used for heating, refining and disinfecting processes of the vegetable oil production. The vegetable oil industry requires a large amount of steam. With high sanitary requirements, the vegetable oil processing companies set high requirements for the quality of steam. YongYou is a large cereals & oils company integrating grain storage, trading, transit and processing. According to the characteristics of high steam pressure, high quality requirements and large load fluctuations in the vegetable oil production process, YongYou purchased two sets of 15 tph biomass-fired steam boilers to meet the requirements of production. In addition, the flexible load adjustment can improve the use efficiency of steam.

Fire Tube Boiler | Operation and Types of Fire Tube Boiler

Aug 22, 2018 · Fire tube boiler is one of the most basic types of boiler and the design is also very old. It was popular in 18 th century. It was mainly used for steam locomotive engines. Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes.
