heavy oil fired water tube boiler

Check gas fired water tube boiler before the preparation of cease-fire and that the flue slow cooling drum; open all manholes and hand holes in the header of the boiler body; let go of the gas within the boiler drum and water; the boiler combustion chamber, drum , flue ducts thorough cleaning; steam pipeline cleaning and removing rust and scale water; repair or replace a manhole cover; ready safelight, flashlights, test rods, tools and the like. Burner gas is an important part of the boiler, the main control system and combustion system components, the problem lies in easy control cabinet, 1. However, the normal ignition off this failure phenomenon typical cause of several tens of seconds after the self-ignition of the burner flame sensor dirty parts. The flame sensor is a photoresistor when irradiated with light of its own resistance decreases resistance value increases as a state of high impedance low impedance state when the light irradiation. Burner flame sensor controller in accordance with a resistance value to determine whether the process is continued if the combustion stop combustion flame sensor high impedance supply is immediately stopped to prevent the unburned diesel fuel reservoir. Flame sensor probe positioned within the burner duct, since the black smoke, tempering, blowing dust and other reasons that the surface thus losing readily soiling the photosensitive functionality. Check sensor probe, its surface is cleaned with a detergent or alcohol, if necessary. 2. Ignition normal exhaust smoke color but not normal diesel fuel injected into the burner is burning the mixture under stirring, when the appropriate amount of blowing water vapor and CO2 exhaust gas atomization are colorless. When there is insufficient air supply can cause incomplete combustion of diesel soot to form CO and thus give rise to the phenomenon of black smoke exhaust. However, if a strong wind inlet excessive combustion of oil mist may be blown off too late will form white smoke is discharged. Common causes of black smoke exhaust of combustion into the throttle opening is too small, white smoke into the throttle opening is reason to see through the large, two cases should be re-adjusted into the throttle. Exhaust smoke color can be observed while the side damper opening degree until near colorless in exhaust smoke color adjustment. Another reason is that black smoke exhaust poor atomization of diesel, oil mist contained in the larger droplets, can not be sufficiently mixed with the air due to a local incomplete combustion produce soot.

Features 1 gas fired water tube boiler, gas boiler configuration Henan imported brand burner, high degree of automation, automatic purge controller in accordance with the instructions, automatic electronic ignition, automatic combustion, wind oil (gas) automatic ratio adjustment, safe and stable performance, good combustion results . And there are flameout protection device, ensure safe operation. 2, the computer controller of formula bath boiler, all the functions are stored on a magic smart chip, a key to power boilers, automatic timing, temperature operation, the user can set the start, shutdown time, after setting, not need special duty to save time, and effort. 3, Henan within a gas flame fire tube boiler interposed spoiler, slow speed exhaust enhance heat transfer, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. Henan operation of gas-fired boiler 1, a large font display temperature, easy to grasp and boiler operating conditions of the system, the water temperature can be freely set from 10 ℃ to 90 ℃, automatic boiler or heating system to provide users with life, bath with hot water. 2, the control system controls the circulation pump start and stop in accordance with the temperature of boiler water, boiler water circulating pump starts when the water reaches an upper limit temperature, lower than the hot water circulation pump stops when the water temperature lower limit. 3, three horizontal gas bath boiler return all wet back structure, using a large furnace, rough smoke tube design, increased furnace radiation heat absorption, the effective energy saving. Using threaded pipe and waveform furnace, greatly enhanced heat transfer effect, greatly saving fuel consumption. 4, while the machine is equipped with thermal protection (ultrahigh temperature furnace, the burner is automatically stopped and an alarm buzzer, the second over protection (the boiler shell temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), the lack of anti-dry protection of water (when water is lower than the low water level of the furnace, the boiler is stopped and an alarm beep), a boiler leakage protection (the control system detects electrical leakage, short circuit, automatically cut off the power) .5, Henan atmospheric gas boiler according design, the boiler is in an unpressurised state, there is no safety hazard. centrifugal using advanced multilayer insulation wool, a steel sheet for packaging famous white color, heat loss, anti-rust appearance.

Gas steam thermal cracking reaction furnace gas steam oven should be carefully introduced reflect in the use, to guard against water, acid, alkali and leakage into the low fired water tube boilers using the system, the system should be installed filters installed to prevent debris into various types, to ensure the purity of the oil . Gas and steam is easily oxidized during heating, the acid value of the oil is increased at high temperatures and a large change rate. Steam oven gas kinematic viscosity gradually increases, which is due to the thermal cracking gas vapor component at high temperature, thermal polycondensation reaction. Thermal cracking reaction resulting in generation of small molecule compounds, to reduce its viscosity; oxidation temperature when the inner conduit thermally cleavage occurs at 300 ~ 400 ℃, coke formation in the pipe, the inner wall of the device, leading to heat accumulation pipe affect the heat transfer efficiency, sludge poor flowability, transfer oil accelerated aging failure, but also to the furnace, pipes local overheating, impairing the mechanical strength of the threat to personal safety.

The partnership, fast fired water tube boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback
