Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast 40 ton firewood boiler in the united kingdom steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
A: the adaptability of the gas sources 1: Natural gas must depressurization gas regulator and gas regulator, the pressure before the Burner selected to meet the requirements before entering the burner, in order to work properly. 2: automatic adjustment operation of the 40 ton firewood boiler in the united kingdom performance requirements: since a large gas consumption of the gas boiler, gas boiler as possible in order to reduce impact (sudden pressure regulator after the gas lift system during starting or stopping, sags ), controlling the gas boiler during operation must meet the following requirements: start (1) gas boiler must be adjusted to start at the minimum load of 30% (the rated load); (2) a gas boiler must be gradually reduced before shutdown load, rated load to be reduced before shutdown when the valve closes the solenoid 30%; (3) boilers can be automatically adjusted according to the boiler heat load during normal operation of the actual output stage operating conditions, automatically increasing demand for large Great demand hours automatically reduced, self-sustained heat balance of supply and demand, greatly reducing the number of start and stop the boiler; when reduced to 30% or less of the rated load, heat production is still greater than the output of the boiler, before proceeding down. (According to relevant statistics, the explosion occurred in the gas boiler start-up and shutdown of these two periods that occurred during ignition and fire in., A small gas boiler gas explosion has occurred 2/3 during ignition) (4) is provided above the automatic adjustment function is particularly important when a voltage regulator with many boilers, the boiler can start to avoid pressure fluctuations caused by stopping overpressure safety device or system boiler gas low-voltage protection action, the normal operation of the boiler shutdown. Two: for gas safety, gas boilers must have security facility 1: ignition control system for a gas boiler before ignition, purge the furnace and flue must be carefully excluded combustible gas furnace may be accumulated. A reasonable ignition process control systems to cope with the ignition process is automatically controlled fan only after the completion of furnace cleaning tasks to perform ignition; only when the ignition flame has been established (confirmed by a flame detector), and after a predetermined time has elapsed, a control valve main burner to open; ignition flame is automatically extinguished after a predetermined period of time; when the main flame could not be ignited within a predetermined period of time, the main burner can be automatically and quickly turn off the ignition flame is extinguished while gas boiler ignition procedures are generally monitored and controlled by a program controller. Control of the ignition process, the ignition before the total ventilation should be not less than 3 times the total volume from the furnace to the chimney population. 2: Safety Devices gas boiler is run prevent excessive wind load caused by a low flame, combustion automatic adjustment device should be installed on each boiler, intake air volume and gas supply gas boiler control linkage.
The method of scale removal by alkali cooking is basically the same as that of the new 40 ton firewood boiler in the united kingdom, but after the boiler is finished, the inspection holes of the boiler should be opened and the mechanical (or high pressure hydraulic) auxiliary descaling should be carried out in time to prevent the soft scale from becoming hard again.
Steam 40 ton firewood boiler in the united kingdom thermal efficiency of gas-related factors and ignition tests: on specific types of boilers, steam boilers for gas this kind, because it is one of the boiler product site, so its knowledge and understanding, it is necessary because only then will we be able to fully understand all the products website, and do not miss any of them. Furthermore, to allow yourself to have a good learning. 1. Gas-fired steam boiler, whether vertical and horizontal points? In addition, their characteristics, what is? Gas-fired steam boiler, which is vertical and horizontal points, and this is very positive. Vertical gas steam boiler, which is a two-pass structure is such that the fuel can be sufficiently combusted. Moreover, its small footprint, high thermal efficiency, can effectively reduce usage charges. Horizontal gas and steam boiler, which is a three pyrotechnic return pipe structure, the advantages thereof, the high combustion efficiency, low exhaust gas temperature, and energy saving can be achieved.
