Use should pay attention to the problem of steam boiler pressure gauge. Rated steam pressure of less than 2.45MPa steam boiler, a manometer accuracy no less than 2.5; equal to the rated boiler steam pressure 2.45MPa, the pressure is not less than 1.5. Dial gauge diameter of not less than 100 mm, to ensure that the operator can clearly see the surface pressure indication. 2. Steam boiler gauge plate should draw a red line that indicates the maximum allowable working pressure. 3. The steam boiler pressure gauge should be installed in place to facilitate the observation and purged, and should prevent high temperature, vibration and icing. 4. The steam boiler pressure gauge should be checked at least once every six months, after calibration seal should be sealed. 5. The steam boiler gauge connection tube not leak water and steam, otherwise it will reduce the pressure instruction value. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass best quality industrial biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 6. A steam boiler pressure gauge measuring range should be compatible with the operating pressure of the device under test, the working pressure is generally 1.53 times, preferably 2 times the working pressure. Steam boiler no pressure gauge, pressure gauge or pressure gauge damage does not meet the requirements. When the steam boiler pressure gauge of the following circumstances, should stop using: 1, the surface of the glass broken or blurred dial; 2, lead-free seal, lead seal is broken or exceeds the calibration cycle; 3. When no pressure gauge pointer position is limited to the limit staple nail can not be restored, and the unlimited gauge pointer from zero rank bit data is out of range pressure layer. Difference; 4, leak or pointer jump table; 5, other defects affect the gauge accuracy.
Fuel oil combustion process differs from the process industry Industrial Combustion fuel oil-fired boilers for industrial oil fired boilers and industrial boilers, having a certain temperature and pressure injected into the furnace through the nozzle is atomized into fine droplets, and then absorbs heat in the furnace, vertical oil-fired boiler, surface gradually vaporized into oil, mixed with intake air in the furnace, form a combustible mixture. The combustible mixture continues endotherm temperature reached ignition ignition combustion. Fuel amount, air amount and the amount of the composite has a one to one relationship of steam, it is necessary according to the load amount of steam required to control the amount of fuel and air supply, but also by the wind furnace pressure control apparatus. Different oil-fired boiler with a different point of industrial coal-fired boilers point of industrial boiler fuel industry and industrial coal-fired boilers. PM2.5 pollution damage to the environment led some coal-fired boilers industrial boilers is facing new boiler renovation or change of situation, which makes oil-fired boiler to become the darling of the market. Oil-fired boiler with a coal-fired boiler in comparison with structurally quite different purposes, as follows: (1) injecting fuel into the boiler furnace through the burner, combustion chamber without using fire grate facilities; (2) Since the oil, gas did not produce combustion ash, it is no oil or gas boiler slag and slag outlet device; (3) injecting a gas or oil furnace materialized, if mixed with air or flame within a certain range, is easy to form an explosive gas, Thus fuel (gas) required automated combustion boiler system, comprising a flame monitoring, flame protection, explosion-proof safety; (4) Since the oil, gas calorific value is much larger than the calorific value of coal, so the thermal strength than fired furnace high multi-furnace, so relatively small and the capacity of the boiler with coal-fired boilers, compact, small footprint; combustion process (5) fuel (gas) is suspended in a boiler furnace, the furnace is provided so its before and after the arch, the furnace structure is very simple. Meter manufacturing, Supervision, Inspection and the main characteristics of biomass fuel boilers  protection devices and control systems introduced a biomass fired boiler biomass fuel boilers are in strict accordance with "Steam Boiler Safety Supervision", JB / T10094-2002 "general industrial boilers technical conditions ", JB / T1619-2002" shell boiler body manufacturing technology, "execution, ensure long-term security and stability of the boilers. Body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, stretched stretch, combustion heat load is low, less NOx emissions of harmful substances. Waveform furnace and threaded pipe structure that improves the strength, but also to meet the needs of each portion of the thermal expansion. Master butt welds are connected, and by X-ray and ultrasonic nondestructive testing, to ensure the welding quality to meet national requirements. Boiler water volume and large air space, adaptable load capacity. Design reasonable pot, with water vapor to ensure that less than 4%, to meet user requirements for higher quality steam. Using the new insulation materials, light weight, low heat loss, good insulation properties. Water level alarm stainless steel rods as electrodes, an insulating material as polytetrafluoroethylene. Inserted from above, linked to pollution easy, reliable, and long service life. Before and after the smoke box is hinged, can easily open, repair and maintenance quick and easy maintenance.

Biomass fuel boiler operation timing of the protection device, the operation of the control system by the timer, the system automatically enters the work or off duty. The control system may be provided multiple sets of the timing period within 24 hours. Any period of time in a group of a plurality of sets of timing of the current time period, the system enters the working state. Work within the timing period, the status screen is displayed automatically. In the period of time in commuting to work outside the state. Each group comprises a turn-on time period (hour, minutes) and a closing time (hours, minutes) may be set or modified when the three control period, divided by the setting operation and the current time. The user can set different time different temperature ranges.
Such boilers are mainly fueled by natural gas, oil, gas, etc. For customers, the fuel used in such boilers is relatively high in price relative to fuels such as coal and biomass. However, the boiler is easy to use and the fuel is transported by pipeline without storage. Biomass fuels, and fuels such as coal, need to be processed in advance when used in boilers, and because of the large amount of consumption, fuel transportation, and fuel storage are not small expenses. However, the oil and gas water boilers produced by ZG boiler do not need these additional inputs.
