Di steam boiler safety valve installation and adjustment of safety valves for steam boilers, its importance is self-evident, its purpose is to protect the safe operation of steam boilers, when the medium pressure steam boilers or pipes increases more than the prescribed the value is automatically turned on, the steam boiler safety shutdown. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass china biomass hot water boiler price in sri lanka, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Safety valve is so important, then for its installation, precautions, the author based on years of experience, in particular, are summarized below. 1. The safety valve safety valve should be installed after the installation of the boiler pressure test and adjust safety valve operating pressure at the first fire. The pressure should 7≤2 provided for in section 143 of the National Bureau of Labor Table "Supervision and Regulation steam boiler safety technology" to adjust. 2. Remove the adjustment valve opening pin, remove the cover, loosen the hex lock nut, the adjustment screw is then screwed, to relax or tighten the spring to meet the required pressure exhaust valve. After adjusting tighten the lock nut, and then install the remaining components. When the valve reaches a predetermined set pressure, it should be sealed lead-sealed, unless the check valve, otherwise not allowed to remove the lead seal at any other time. First, when adjusting the safety valve, the water level should be slightly lower than normal water level of the barrel, and ready to enter the water when the safety valve is opened. Second, do not knock any part of the safety valve, the safety valve can only be opened using the valve control lever. Finally, the boiler is absolutely prohibited until the safety valve is adjusted.
Gas-fired steam boiler applications include gas steam boiler steam boiler and china biomass hot water boiler price in sri lanka two categories, under the policy from coal to gas, the use of gas steam boiler is also increasingly widespread up. Regional gas boiler is also engaged in the implementation of replacement or renovation project. Then come to you simply steam boiler applications have what? Steam boiler applications can be roughly divided into three categories, residential, commercial and industrial, civil and generally refers to the domestic gas boiler our lives with so-called boiler, primarily for home heating and bath with hot water , which is characterized by simple structure, convenient operation, long life, is the choice of most families choose; commercial, then generally refers to the star hotel, hospital school district heating mechanism, the general will choose to steam bath or gas boiler boiler for hot water supply of the main ways. Required in this area to select a gas boiler, characterized in that the gas or gas compared in terms of biomass fuel, no dust combustion, emissions in the flue gas can also control the amount of nitrogen emissions. Gas-fired steam boiler combustion more fully in value, mostly in the commercial is also a good choice; the last is the industrial furnace, industrial furnace is characteristic of large tonnage, high fuel demand, in general, the company received the heat a gas pipeline to gas as fuel, then the biggest advantage is that no storage, reducing transportation and storage costs of fuel, generally used for thermal power generation or industrial heating and heating company needs large industrial enterprises. These are the three main areas of use on gas-fired boiler to introduce today, hoping to help you have a better understanding of steam or hot water boiler, also hope that we can continue to focus on.
Fast boiler particularly strong technical team, they listened carefully to our needs and give us tailored technology solutions, from boiler production, transport to the site installation and commissioning took only 35 days time, all aspects of the deal in place, the boiler quickly it is put into use. --customer feedback
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 china biomass hot water boiler price in sri lanka, 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.
